Beware Caesar! Hail Caesar!

A curious development took place in the astrology of Rome as the strife-torn Republic was convulsed into an orderly Empire at the close of 1st century B.C.E. This article explains how two very different events, separated by 164 years, shed light on the now evident shift from a sidereal zodiac, reflecting the visible constellations in the sky, to the tropical zodiac, with its ceaseless drift away from its visible moorings. This articles purports to explain the underpinnings of the shift. 

Beware Caesar!
Julius Caesar's stunning military successes in Gallia made him suspect among the landowning Senatorial class in Rome. While they prized civic duty of leading a Roman army, they abhored any man that usurped too much power in so doing, as he thereby created a threat to their ability to manage the delicate balance of power the Republic relied on. The example of dictatorial rule by the early Roman kings had made republicans afraid of a relapse into it. While their own Senatorial rule had devolved into an indefensible exploitation of the Roman masses, that was secondary for most of them. Making things more delicate, Caesar was a professed 'populares'. Upon his long awaited return to Rome, the Senators demanded that Caesar relinquish his military power and submit to a trial over his actions in Gallia. Rather than comply, Caesar violated a cardinal rule and entered Rome with his troops, setting off a bloody civil war. After handily winning that war, Caesar tried to placate his surviving enemies, but his actions, including to declare himself Dictator for life in 46. B.C.E., made them only more adamant to secretly conspire to "kill the tyrant".

According to Suetonius (69 A.D. – 122 A.D.), the Roman historian, it was Spurinna, alternatingly referred to as a haruspex, seer or soothsayer, who warned Julius Caesar of danger to his person leading up to the Ides of March [1]. "Beware the Ides of March, Caesar!" is a phrase forever etched in the collective memory. A haruspex was the term for those who studied the entrails of animals as a form of divination. However, it is more than likely Spurinna knew astrology, as the practice was already established in Rome at that time, and Spurinna used an astrological concept, Eidus, or Ides, to warn Caesar. The Ides are imbued with astrological meaning, as they represents the time when the Sun passes from one sign to another. Indeed, the word means "divide," as between two signs and the month itself, as the Ides took place in the middle of the month. Thus, on March 15, the Sun moved from Pisces to Aries. In the Systems' Approach astrology, the Sun becomes weak as it passes from old age of one sign to infancy in another, much like the journey of a soul from a frail body at the close of one earthly existence, to the birth in a small and dependent new one.

Importantly, the Eidus Martiae" coin, seen above, which was commissioned by Brutus in 42 B.C.E. to celebrate Caesar´s death and the restoration of "freedom" in Rome, is clear evidence of the importance of the Ides of March legend in the death of Caesar. For archeologists there is no better proof.

The famous interaction between Caesar and Spurinna is reported as follows.
"In grave tones, Spurinna warned the dictator that his life would be in danger for a period of 30 days, which would expire on the 15th of March. Caesar dismissed the concerns. [...] As the 30 days passed, nothing whatsoever happened. Yet when the 15th of March dawned, Caesar’s wife awoke distressed after dreaming she held his bloodied body. Fearing for his life, she begged him not to leave the house. His dreams, too, had also been unsettling. He had been flying through the air, and shaken hands with Jupiter. But he pushed any concerns aside. The day was an important annual celebration in Rome’s religious calendar, and he had called a special meeting of the Senate. His first appointment of the day was a quick sacrifice at a friend’s house. Spurinna the seer was also there. Caesar joked that his prophecies must be off as nothing had happened. Spurinna muttered that the day was not yet over." 

 This exchange suggests that Spurinna considered the 30 day threat over once the Sun moved out of Pisces and into Aries, it's exaltation sign. Indeed, it takes the Sun 30 days to move through one sign. By comparison, the weakness from old age to infancy only lasts for 10 days. This interpretation gains more credence when we consider a possible horoscope for Caesar. 


Spurinna may have had knowledge of Caesar's birth information. What we know of Caesar, the sign Libra could fit his tall and impressive appearance and conduct. Here is a speculative natal chart for him. In it, Caesar has 12th lord Mercury conjunct 1st lord Venus in the MEP of the 10th house, suggesting public efforts abroad, in aspect to 5th lord Saturn, suggesting intelligent execution giving satisfaction. However, problems are also for self (1) and mind (5) from the most malefic planet (MMP) Mercury. Caesar is said to have suffered from epilepsy. 

Caesar's tall height would be explained by 5th lord Saturn, which rules tall height, being in the MEP of the 4th house from where it aspects the 1st house of self and 1st lord Venus in the 10th house MEP. An additional influence is that, 3rd lord Jupiter, ruling growth, is in the 8th house MEP from where it aspects Saturn.

The placement of 3rd lord Jupiter in the 8th house also gives obstacles for Caesars initiatives and actions, as well as easy gains. Meanwhile, Ketu in the 2nd house aspects his 2nd lord Sun in the 10th house, suggesting spiritual or misunderstood efforts on behalf of the downtrodden, but also sudden, explosive setbacks to his authority and status. Indeed, as a young man he was marked for death by Sulla, fled Rome, only to be captured by pirates, requiring a ransom, which arrived at the last minute, saving him from certain death. All his conquests in Gallia added enormously to the Roman coffers, but these contributions were overlooked by the Senators, who had grown fearful of him. Caesar, who had made generous offerings to the plebeians in his lifetime, also in his will bequeathed a big part of his estate to them.

In any event, on March 15, 44 B.C.E. the Sun as 11th lord for Librans was in late Pisces, where it was conjunct a debilitated 12th lord Mercury. Functional malefic (FM) planets become more malefic when weak. Importantly, Pisces becomes the 6th house of enemies for Librans. At that time it was possibly in the most effective point of the 6th house, or near Caesar's rising degree, where it has more influence, conjunct the MMP ruling losses. Influential Senators, whom Caesar treated as friends, especially Brutus, betrayed his trust and killed him. Other things, like planetary periods would likely have been involved in such a dramatic event.

The transition from sidereal to tropical astrology
Roman astrology came from Greece. The link between Hellenic and Roman astrology is made clear by Wray (2001)
"Every emperor's biography seems to have featured some omen or prediction of future greatness, so on one level there's no reason to attach any truth value to this story about Augustus and a Greek astrologer. On the other hand, there is nothing impossible or unlikely about an astrologer making a prediction of future greatness and power to Augustus as early as 44 BCE. Astrology was a part of Greek learning and culture, with a high prestige value. And more importantly, individual natal horoscopes tended to be associated in the Hellenistic world with individual power, and specifically with claims to kingship. Publishing your horoscope, in other words, could be read as a way of making a bid for royal power without having to say openly that you were making such a bid. The first "published" horoscope we possess dates from 62 BCE. It is preserved in the form of a relief carved into a rock on the top of Nimrudh Dagh in the Tarsus mountains, and it represents the coronation horoscope of King Antiochus I of Commagene".
There is also an established earlier link between Indian and Hellenic astrology, involving the transmission of ideas associated with the conquest of Alexander the Great in India, in the 4th century B.C.E. It is known that proto-astrology was a part of the ancient Vedas, and that much later, in the 7th century B.C.E., there was a precursor of horoscopic astrology in India. Moreover, later, the Indians were known to use only the sidereal zodiac.

What matters most is that the original Greek horoscopic astrology emphasised the rising sign and related house placements of the planets. The evidence points to the Greeks having also used the sidereal zodiac, and hence the early practice of astrology in Rome did the same. We can see this from the placement of the Sun during the Ides of March in 44 B.C.E., with the Sun at 29° Pisces in the sidereal zodiac, while it was at 24° Pisces in the tropical zodia and outside the old age/infancy zone. Hence, it was clearly the sidereal zodiac Spurinna was basing his astrology on.

We can also see how the placement of the Sun, on this day, have changed over time for each respective zodiac.

15 March, 44 B.C.E.: Sidereal Sun:  28° 52' Pisces; Tropical Sun 24° 19' Pisces.
15 March, 1000 A.D.: Sidereal Sun: 14° 37' Pisces; Tropical Sun 24° 34' Pisces.
15 March 2021 A.D.: Sidereal Sun:   0° 53' Pisces; Tropical Sun 25° 02' Pisces.

Today, the Sun has moved further back in Pisces on March 15 in the sidereal zodiac, in line with the travel of the visible zodical constellations in the sky, due to the precession of the equinoxes. However, the Sun still appears in late Pisces, but not old age, in the tropical zodiac, far out of synch with its constellational moorings. 

In the event, it was Augustus, the adopted son of Julius Caesar, who won the second civil war, following Caesar's murder, besting also his ally Marc Anthony, to usher in the new order, the rule of the emperors, the Caesars.

At the same time, it is in this transformation we can also see how the sidereal zodiac faded out of view in the Roman Empire, to be replaced by a default zodiac, rooted in non-astrological dictates, and which later became known as the tropical zodiac.

In 45 B.C.E. Julius Caesar introduced the Julian calendar, which was, importantly, based on the solar-year. It's predecessor, the Roman calendar, was a very complicated lunar calendar, based on the moon phases, which proved difficult to keep in sync with the astronomical seasons, marked by equinoxes and solstices. The Julian calendar made this easier. This change coincided with making a single leader the nucleus of Roman society.

Hail Caesar!
One aspect of the Roman empire was the central role of the Emperor himself. His person became the nucleus of the social order and his place in the firmament was that of a divine being. History has witnessed many such kings, who commanded or demanded the absolute acquiescence of all the citizens to not only their rule but to their undisputed greatness. The madness of Caligula and Nero serve as reminders. The modern term for this mental condition and behaviour is megalomania. It was nevertheless an accepted feature of life in Rome at that time, and it was in fact required for the good functioning of the state itself.

In 120 A.D., the Pantheon as we know it today was built by Emperor Hadrian. He seems to have been a good emperor, as they go. An interesting insight concerning the Pantheon is that he was so passionate about its architecture that he had Apollodorus of Damascus, a famous Greek architect of the time, executed due to an argument about the design of the temple. Perhaps the most stunning feature of the Pantheon is its spherical roof with an opening at the top, the Oculus, and its relationship to the huge entrance.

The design had the singular purpose on t
he day when the Romans celebrated April 21 as the founding date of the city, for the sunlight at noon to enter the Oculus and strike a metal grille above the doorway, saturating the courtyard outside with light, as well as bathe the Emperor standing in the entrance of the Pantheon in light. For the ancients, as moderns, the Sun in mundane astrology rules the leader. The effect was to raise the new Emperor to the level of the gods; affirm his divinity.

The importance of astrology to Hadrian is well known. His horoscope that survives from the 4th century A.D. was cast in the tropical zodiac. More importantly, Hadrian knew its symbolism, deriving only from the tropical placements, as these became a part of the Pantheon's designJoost-Gaugier (1998) describes it thus:
"By counting the essential parts of the building and relating those numbers to its shape and function, the structure clearly 'reads' as the Marriage of the Sun and the Moon. Hadrian's horoscope, well known to scholars of classical astrology, sets forth the time of his birth as occurring at a moment of 'coincidence' of the Sun and the Moon. His earliest biographers underline his special interest in the Sun and the Moon which corresponded with his Pythagorean interests."
Moreover, on April 21, 120 A.D. in the uncorrected zodiac, the Sun entered the sign Taurus, a fruitful and earthy sign, fitting the sensible nature and practical philosophy of Hadrian. Perhaps it was to preserve this degree of 'beginning' on that day that a decision, involving the court astrologers, was effectively made to follow the tropical zodiac. Interestingly, this would also place Hadrian's own Sun, Moon and ascendant, all in Aquarius, in the auspicious rulership oriented 10th house. Hence, the Pantheon likely reflects his own horoscope, which is fascinating.

The decision to build with this horoscopic interpretation, based on the tropical zodiac becomes perhaps more understandable as it was only in the 3rd century A.D., with the sideral zodiac having moved 2° with reference to the calendar, that the two zodiacs became identical, the so-called zero point. So, the change to a new zodiac may have been seen as fairly inconsequential at the time.

The tropical zodiac may have been known by the Greek astrologers in the 2nd or 1st centuries B.C.E., however, it was then not widely used. Astrology was still sidereal as is shown above in the time of Julius Caesar, and Augustus. The key to the sidereal zodiac was to keep 0° Libra on the fixed star Spica (Chitra). It is more likely that for the above reason that the correction for the precession of the equinoxes, in order to keep the constellations and signs aligned given the 1° movement every 73 years, was abandoned in casting horoscopes in the Roman Empire. The Pantheon codified the tropical zodiac. Even the ascendant shifted from the top of the horoscope, as is still the case for vedic astrology, to the left, as is still the case for western astrology, and thus reflecting the crimson dawn of the rising Sun in the East. Indeed, the Sun gained primacy in western astrology, while the rising sign remains the focus of horoscopic astrology. Interestingly, the Sun and sign Leo, and sun-like planets, ruling Moolatrikona signs falling in the 2nd, 3rd and 9th houses, have a special power in the modern vedic Systems' Approach astrology. In any event, these changes also ensured that the Emperor could count on being reaffirmed as a divine ruler on this important day, especially, as it ensured the astrology was consistent with the optimal optical effect on April 21 for posterity. 

However, the result for astrology was a sad one. It ensured that western astrology continued to devolve from its sidereal horoscopic basis as practiced by the Roman's, with the difference between the zodiacs increasing from the 3rd century A.D. into the Middle Ages and beyond. Today, tropical astrology has become so shorn of its earlier accurate sign placements, that it is almost one sign removed from the original constellations. Moreover, its distorted emphasis on the Sun placed in an imaginary sign, ensures that it misses out on the critical ingredient of the accurate house-based horoscopic astrology. Fortunately, vedic astrology, the original fountain of this knowledge, both in the East and the West, has continued to this day, with the correct zodiac based on the visible constellations, and its true horoscopic approach.

Ptolemy's mistake (and the origin of Western astrology)

The name of Ptolemy, the astronomer, cartographer and astrologer, has become almost legendary as representing a multifaceted scholar during the declining phase of the Hellenic world. This impression may be largely undeserved. In fact, the writings and many errors made by Ptolemy suggest he was not the expert his books made him out to be. Importantly, he adopted an astronomical calculation concerning the starting point of the zodiac which resulted in a fictitious moving (tropical) zodiac being populalrised. This was undoubtedly based on a misunderstanding and his advocacy of this calculation in his book resurfaced in Europe during the Renaissance in the late Middle Ages and became the basis of the birth of modern Western astrology.

Claudius Ptolemaeus
Claudius Ptolemaeus (c. AD 90 – c. 168), known in English as Ptolemy, was a Roman citizen of Egypt who wrote in Greek. He was a mathematician, astronomer, geographer, astrologer and a poet of a single epigram in the Greek Anthology. He lived in Egypt under Roman rule and died in Alexandria around AD 168. Ptolemy was the author of several treatises, at least three of which were of continuing importance to later Islamic and European science. The first is the astronomical treatise known as the Almagest ("The Great Treatise“). The second is the Geography, which is a thorough discussion of the geographic knowledge of the Greco-Roman world. The third is the astrological treatise known as the Tetrabiblos ("Four books"), in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day.[1]

Errors in calculations
While evidently accomplished as a writer and celebrated during the middle ages, the originality of his works has been cast in doubt due to his unfamiliarity with the astrological practices of his time and the many important errors made in his books. His importance is not least traced to his major work, the Almagest, which is the only surviving comprehensive ancient treatise on astronomy in the Hellenic world. Indian and Babylonian astronomers had developed arithmetical techniques for calculating astronomical phenomena; Greek astronomers such as Hipparchus had produced geometric models for calculating celestial motions. Ptolemy, however, claimed to have derived his geometrical models from selected astronomical observations by his predecessors spanning more than 800 years, though astronomers have for centuries suspected that his models' parameters were adopted independently of observations. Ptolemy presented his astronomical models in convenient tables, which could be used to compute the future or past position of the planets. Later, it was demonstrated that his ephemeris is of dubious quality, diverging significantly from the calculations of his contemporaries. Because Ptolemy derived many of his key latitudes from crude longest day values, his latitudes are erroneous on average by roughly a degree (2 degrees for Byzantium, 4 degrees for Carthage), though capable ancient astronomers knew their latitudes to more like a minute. He agreed that longitude was best determined by simultaneous observation of lunar eclipses, yet he was so out of touch with the scientists of his day that he knew of no such data more recent than 500 years ago (Arbela eclipse). In terms of cartography, when switching from 700 stadia per degree to 500, he expanded longitude differences between cities accordingly (a point first realized by P.Gosselin in 1790), resulting in serious over-stretching of the Earth's east-west scale in degrees, though not distance.

Ptolemy‘s popularity was based on his Handy Tables, a useful tool for astronomical calculations and a model for later astronomical tables. In the tables was tabulated all the data needed to compute the positions of the Sun, Moon and planets, the rising and setting of the stars, and eclipses of the Sun and Moon – albeit with a large margin of error. Ptolemy‘s Planetary Hypotheses went beyond the mathematical model of the Almagest to present a physical realization of the universe as a set of nested spheres, in which he used the epicycles of his planetary model to compute the dimensions of the universe. He estimated the Sun was at an average distance of 1210 Earth radii, which is one twentieth of the actual distance. Meanwhile, he calculated the radius of the sphere of the fixed stars as being 20,000 times the radius of the Earth, or within the distance of the Sun. It is uncertain if other astronomers of his day were so widely off in their distance calculations.


Certainly, his most crucial error was in failing to correct for the precession of the equinoxes in order to anchor the zodiac and the fixed planets which make up the constellations in the sky. Rather, he and some other Roman astrologers, chose not to make this correction. At that time, the difference between the classical sidereal zodiac was only a few degrees. However, by the time astrology was rediscovered in the West, almost a millennium later, the difference had grown in size by over 10° and at the present time it is 24°. In some few hundred years, the signs in the tropical zodiac will be one whole sign removed from their original counterparts in the sidereal zodiac. Clearly, those failing to make this adjustment did not anticipate that development.

A narrow view of Astrology
Ptolemy's treatise on astrology, "Tetrabiblios" (Greek tetra means "four", biblos is "book"), was the most popular astrological work of the middle ages and had great influence in the Islamic world and the medieval Latin West. It was translated from Arabic into Latin by Plato of Tivoli. However, its later popularity also reflects the dearth of written sources on this knowledge at the time. The Tetrabiblos is an extensive and continually reprinted treatise on some principles of astrology that Ptolemy felt were important. That it did not quite attain the unrivaled status of the Almagest was likely because it did not contain a very rigourous treatment of the subject matter in terms of horoscopic astrology proper, thus eluding a comprehensive approach.

The great popularity that the Tetrabiblos did possess might be attributed to its nature as an exposition of the art of astrology and as a compendium of astrological lore, rather than as a manual. It speaks in general terms and avoids illustrations and details of practice. Much of the content of the Tetrabiblos was collected from earlier sources; Ptolemy's achievement was to order his material in a systematic way, showing how the subject could, in his view, be rationalized. At the same time, it reveals that Ptolemy was not an expert on the subject. Ptolemy was concerned with the influences of the celestial bodies which he believed travelled in the sublunar sphere, with a focus on planetary attributes in terms of their heating, cooling, moistening, and drying influences. In short, the astrology he described was a very limited expression of the horoscopic astrology of the day, as documented for instance in the contemporary Yavanajataka, the astrology of the Yavanas (Greek speaking people of the Indo-Greek world). This only points to the fact that Ptolemy did not truly understand the import of his woeful recommendation to calculate the zodiac without a precession correction.

Greek and Roman world
The introduction of the ancient astrology of India into the religious and philosophical milieu of the Hellenic and Roman world are also of interest. The mentaility of this time and location was different from the more ancient vedic civilisation. The nascent Western civilisation was more materialistic and positive in approach but also politheistic. While the Greek people saw the Olympic gods as supermen, rather than an all pervading single deity, the thinkers and heterodox religious leaders of the day debated various philosophical points including the role of gnosticism in religion. Already in the time of the Hellenic world, the ideological soil had become inhospitable to the original horoscopic astrology of Jyotish, as the sixth branch of the vedic science of enlightenment. Moreover, as the Western civilisation moved westward to the Roman empire, the distance between the source of this wisdom in India and its Western practitioners increased. As a result, even the horoscopic astrology began to change in terms of the graphical representation and the placement of the ascendant in the horoscope as documented in earlier articles on Roman Astrology.

During the rediscovery of astrology in the West in the Middle Ages, the practice of this nascent astrology incorporated the essential mistake of Ptolemy. Moreover, as astronomy began to develop into a proper science, even the modern view of astrology recast it as a quasi scientific law of physical causality, as opposed to a law of mysterious karma. Moreover, since Christianity of the fourth century had taken a hostile view of astrology, it had already then been pushed into the shadows and been slowly taken over by lesser practitioners. During the final centuries of the Roman empire astrology had become something of an art for swindlers, soothsayers and fortunetellers. By comparison, in India, astrology kept its moorings in a God centered world view including the theory of karma and the saintliness of the practitioner.

Isolation of Europe in the Middle Ages
To understand this development further we should note that following the fall of the Western Roman Empire in 476, the Middle Ages were born. This was a period of European history until the 15th century when the early Modern Era began. The term "Middle Ages" was coined in the 15th century and reflects the view that this period was a deviation from the path of classical learning, a path supposedly reconnected by Renaissance scholarship.[2] A part of this period, the early middle ages, has been termed the "Dark Ages“, noted for its cultural and economic deterioration as well as the major disruption in Western Europe. Importantly, the singular outside contact of European civilization was with early Islam of the Middle East and Northern Africa, and not India.[3] While this civilisation had protected some of the knowledge of the Roman and Greek worlds, it proved to be a not so hospitable to its internal consistency, by subjecting it to further speculative development.

To compound the problems further, astrology, had begun to fall out of favour in Rome as early as 321 A.D., when the Christian Emperor Constantine issued an edict threatening all Chaldeans, Magi, and their followers with death. As a result astrology disappeared for centuries from the Christian parts of Western Europe. Moreover, the early Christian legend distinguished between astronomy and astrology by ascribing the introduction of the former to the good angels and to Abraham while the latter was ascribed to Cham. Around this time, St. Augustine (354 – 430 A.D.), one of the most important figures in the development of Western Christianity, became active in the fight against astrology, moulding attitudes towards it for centuries to come. Even in Britain of the Enlightenment the practice of astrology was outlawed. Meanwhile, the original Vedic science of astrology has remained a part and parcel of Hindu society and is even openly taught at the university level.

Muslim invasions
The general decline of Western Civilisation during the Early Middle Ages was marked by trends of depopulation, deurbanization and increased barbarian invasion. North Africa and the Middle East, once part of the Eastern Roman Empire, were conquered by Islam. The islamisation of Spain took place from the beginning of the 8th century AD to the end of the 15th. Al-Andalus was the Arabic name given to a nation in the parts comprising most of what is now Spain and Portugal and governed by Berbers and African Muslims (given the generic name of Moors), at various times in the period between 711 and 1492.[4] The Moors were religious fanatics who subjugated these European territories as a part of the caliph of Damascus which was the capital of the Muslim world. Already in the 8th century the Christian Reconquest began, with the last vestiges of islam being pushed out in the Spanish Inquisition from 1478. The reaction resulted in the Crusades. In part, this cultural trend shows a singular focus of Westerners on the Biblical setting of the life story of Jesus Christ.

The Crusades
In the 10th century, the feudal system was established, which allowed a return to systemic agriculture. This trend was followed by sustained urbanization in northern and western Europe. During the High Middle Ages (c. 1000 – 1300 A.D.), Christian-oriented art and architecture flourished and Crusades were mounted to recapture the Holy Land.[5] The Roman Catholic Church sanctioned wars to be undertaken in pursuance of a vow and directed against infidels, i.e. against Muslims, pagans, heretics, or those under the ban of excommunication, called the Crusades. The specific crusades to restore Christian control of the Holy Land were fought over a period of nearly 200 years, between 1095 and 1291. Other campaigns in Spain and Eastern Europe continued into the 15th century. This exclusive interaction with the Arab world during the Middle Ages was only broken with the voyage of Columbus to the New World, but its influence has proved especially long lasting in the field of astrology.


Conclusion
Ptolemy made many contributions to science by documenting valuable astronomical, cartographical and astrological information. However, he was not an expert on horoscopic astrology or its history and his limited understanding of the visible zodiac of the fixed stars and constellations resulted in his adopting an erroneous astronomical representation of a moving zodiac, which, along with a removal from its authentic vedic source during the Middle Ages, had devastating implications for the development of astrology in the West, by undermining its efficacy as a true science of human karma. In fact, by altering the axiomatic principles of astrology itself, Ptolemy's mistake plunged Western astrology far into the shadows as the Age of Enlightenment rose. Fortunately, the classical principles of the original Greco-Indian horoscopic astrology were preserved in Hindu civilisation, even during the periods of Islamic (Mogul) and Christian (British) colonisation.
