Calendar cycles in Ancient Egypt

Because of our earlier discussions concerning the appropriate dates for the heliacal rising of Sirius and the start of the Egyptian New Year, I decided to do more research into the foundation of the Egyptian calendar system. Unlike the Gregorian calendar that we use in the West, which is based on Greco-Roman calendars developed for use by the early Christian Church, the sacred calendar of ancient Egypt never used an adjustment for the fact that the true Solar year is 365.243 days long. Nor did they adjust for the Sirian (Sothic) year (the sidereal year between subsequent heliacal risings of Sirius) of 365.25 years. Instead, according to Robert Bauval (2008) and others, the priesthood allowed the seasonal/festival calendar to "float" as part of three main cycles.

The first cycle is the 365-day calendar year, with no adjustments. This is the calendar that they broke into 3 seasons—Aakhet (Inundation), Peret (Emergence), and Shomu (Harvest)—of 4 30-day months each. Each 30-day month was further divided into 10-day decades or dekans, which provided the standard civil "week" for work. The dekans were timed by the heliacal rising or culmination of specific stars or star groups, allowing the ancient Egyptians to define their 12 hours of the night throughout the year. The 5 Epagomenal Days were added at the end to bring the year-count to 365, the nearest integer relationship to the real year.

The second, or "Sothic" cycle, of 1460 years related the heliacal rise of Sirius to the 365-day year such that the 1st day of the calendar, Wp-rnpt, or 1 Tekhi 1Aakhet, shifted forward 1 day every four years. In 1460 years, the 365-day calendar would complete a Sothic cycle, and 1 Tekhi 1Aakhet would again coincide with the heliacal rising of Sirius. In the intervening years, the seasons would gradually cycle around the 365-day calendar, ending up out of synch with the rising of Sirius at a predictable rate.

The third, or "Solar" cycle, of 1506 years timed the return of 1 Tekhi 1 Aahket to the Summer Solstice, which is (or was) the actual starting point of the annual Inundation. The shift in Wp-Rnpt across the Solar cycle works out to a little over 1 day in 4 1/4 years, so that in 753 years, New Year's day would have moved to the Winter Solstice. According to Bauval (2008), this is the reason the Egyptian capital moved south to Thebes when it did; Re-Horakhty, "Horus in the Horizon," had reached his southernmost point, that of the Winter Solstice. This corresponds with the reign of Mentuhotep II (2061 - 2010 BC), who is documented as reuniting Egypt and moving the capital from Memphis to Thebes.

We know from a Roman commentary by Censorinus that a new Sothic cycle began on the 21st of July in 139 CE, i.e., that 1 Tekhi 1 Aakhut coincided with the heliacal rising of Sirius on that date. Working backward, Bauval (2008) found that in about 2781 BC, all three cycles came together, with the heliacal rising of Sirius occurring on the Summer Solstice, 21 June, at which point the annual Inundation began. Thus, he contends this is the starting point of the religious/festival calendar, which makes sense, and that the priests and the pharaoh took oaths to maintain the calendar in accord with this unique point in time—the establishment of Ma'at (cosmic order).

Once the Heliopolitan focus moved to Thebes in around 2028 BCE, the Solar religion became syncretized with the local cult of Amun. The Temple of Karnak, principal temple of Amun-Re, is aligned with the Winter Solstice sunrise, in accord with the shift in the Solar year recognized by the priest-astronomers. Indeed, one of the epithets of Thebes is the "Heliopolis of the South." Then, in 1275 BCE, at the end of the Solar cycle, Ramses II moved the capital back north to Pi-Ramses.

So, we know that the Egyptians took note of the endings of both the Sothic and Solar cycles, largely according to how they oriented their temples and whether those temples were associated with the Solar or Stellar (Sothic) cults. (And, please, don't harrass me about the use of the word, "cult." I am using it here simply to distinguish between two sets of festival cultures, not as a perjorative.) Bauval (2008) notes that archeological digs at the temple of Satis at Elephantine show shifts that track the location of Sirius along the horizon as it moved northward due to precession. Other temples and 4th and 5th dynasty pyramids also show these alignments and their change over time.

If we choose to perpetuate the Sothic cycle observed by the Stellar/Osirian culture, working forward from 139 CE, we completed the last cycle in 1599 CE, and are currently 412 years into the next. Since we know the Sothic cycle moves the calendar forward 1 day in every 4 years, we can see that the current Wp-rnpt occurs 103 days after the start of the last Sothic cycle's beginning. We also know that the date of Sirius' heliacal rise has precessed forward to 8 August at the latitude of Cairo (Iunu or Heliopolis), so the start of the calendar, 1 Tekhi 1 Aakhet, should shift forward 103 days, to the 19th of November. We won't resynchronize with the actual heliacal rising of Sirius until 3059 CE!

If we are, instead, following the Solar/Re cycle, 2011 CE is 274 years since the last Solar cycle returned 1 Tekhi 1 Aakhet to coincide with the Summer Solstice. The starting date of the calendar would again be moved forward approximately 67 days to coincide with 27 September. In future years, as the calendar passes through Autumn Equinox and on toward the Winter Solstice, we would see a shifting in ritual and political energy from Lower Egypt back into Upper Egypt. It appears that the priesthood mainly used the Solar cycle to establish the current "place of power" or rulership according to the relationship between Wp-rnpt and the Sun on the horizon, which they named Horakhty or Horemakhut, and consolidated with Re. (Note: The ancient Egyptian name of the Sphinx, who stares at the Eastern horizon awaiting the sunrise is Horemakhut.)

Given that the priesthood of ancient Egypt allowed the calendar to "float" in this way, from one perspective we can simplify our celebrations by simply choosing a date and sticking to it, whether that is the 15th or 21st of July (the 139 CE date of the last recorded Sothic cycle's start), or the 1st or 8th of August that coincides with the current heliacal rising of Sirius. Bob Brier's (1980) example of the "Cairo Calendar" from the New Kingdom era starts on 1 August, which makes it convenient to align with our more familiar Gregorian calendar.

However, if we truly wish to synchronize our worship with the cyclical nature of the calendar as the Egyptian priesthood would do, then we need to take the Sothic cycle into account, and start our current ritual calendar on 19 November. We would then celebrate the 2011 Epagomenal days starting on 14th of November, and Wp-Rnpt, New Year's Day, on the 19th. The heliacal rising of Sirius would fall in the first month of Shomu.

I will go back and add various festivals, including lunar ones, at a later point. It would help if my readers could let me know which festival dates are most significant. Ultimately, I hope to make a general calendar. But I would appreciate feedback as to the use of the shifted dates, and how my readers feel that would affect their practice.

As to the month names and the Gods or Goddesses governing them, I used Budge's Egyptian Hieroglyphic Dictionary to look up the ancient names of the months, and the God and Goddess correspondences using Budge's Gods and Goddesses of Egypt.

The first month of the Season of Inundation (Aakhet) was called Thoth by the Copts, and Tepi-Hai-t by the ancient Egyptians, which means "Head of the flood," or "Weeping Goddesses." It was ruled by Tekhi, a title of Djehuti as the keeper or establisher of Time. The word, Tepi, means 1st, and the first day of the New Year was also known as "Tepi Rnpt."

The second month of Aakhet was called Paopi by the Copts, and Penip-t or Penap-t by the ancient Egpytians, and can be loosely translated as "This [month of] Apit," one of the Goddesses associated with the month. The principal God ruling the month is Ptah-ineb-res-f, or "Ptah, South of his Wall," one of the epithets of Ptah of Memphis (Menefer, Aneb). Also, the twin Goddesses Merti represented the flood in Upper and in Lower Egypt. Merit-shemay, the Goddess of the southern inundation, was depicted with a red dress, reflecting the red soil that came down the Nile at the beginning of the Inundation. Merit-meh, Goddess of the northern inundation, wore a blue dress, reflecting the Delta of the Nile.

The third month of Aakhet was called Athyr by the Copts, and Het-her (Hathor) by the ancient Egyptians. While Hathor ruled this month of peak Inundation and the beginning of its end, she also shared features with Sekhmet, who rules the final month of Aakhet.

The fourth month of Aakhet was called Koiak by the Copts, for the festival of Sekhmet, Kherka-heb. In this month, the flood would have ended and the new land begin drying out; it was a month when flies and other insects began decomposing the matter brought down by the flood, and of fevers and illness. (Hence its association with Sekhmet.)

The first month of Peret was called Tybi by the Copts, possibly in association with the birthing bricks women used, or as tiles representing the dry soil to be broken for planting. The ancient Egyptian name for the month, Ames ams-t, ties the month to Min-Amsu, who gives birth to plants, and represents the reproductive powers of nature. Another Goddess of this month is Shef(t)-betd-t, meaning "makes swell the grain," and represents the new shoots of the crops.

The second month of Peret was called Mekhir by the Copts, and M'khir or M'khiaru by the ancient Egyptians. M'khir means "granary," m'khiaru means "food, sustenance," so the name seems to project hope for the upcoming harvest as it grows. The Goddess of this month is Rekh-ur, and the only thing I can find about her is what the components of her name mean: "Rekh" means "wise" and "ur" means "growth." So this is the Goddess who is wise/skilled in growth, who helps the crops grow.

The third month of Peret was called Phamenoth by the Copts, and Pen-Amen-htp by the ancient Egyptians, meaning "This [month of] Amen's peace." The Goddess of the month is Rekh-netcher, whose names means "wise in harvest," or "wise in holding fast," leading up to harvest. This would have been the time the farmers would have begun sharpening their tools for the upcoming harvest of grain.

The fourth month of Peret was called Pharmuthi by the Copts, and Pen-rent, "This [month of] harvest," by the ancient Egyptians. The month was sacred to Rennuttet, a snake-headed Goddess of the Harvest associated with Isis, and possibly the constellation of Virgo.

The first month of Shomu was called Pachons by the Copts, and Pa-khons by the ancient Egyptians, meaning "Son of Khons or Khonsu." Khonsu was the God of the month, possibly for his association with a sickle-like weapon he carried.

The second month of Shomu was called Paoni by the Copts, and Pen-ant, "This [month of] Anit," by the ancient Egyptians. Anit was one of the mothers of Heru-pa-khart, son of Isis, and so can be considered a form of Isis. The God of the month was Heru-khuti-khadit, "The Unborn Horus." on the 11th day of this month, ancient Egyptians celebrated Gerh en hati, "The Night of the Drop," a festival for the Tear of Isis believed to trigger the annual inundation.

The third month of Shomu was called Epiphi by the Copts, and Ipip by the ancient Egyptians, possibly meaning "measuring up the harvest." The Goddess Apit, a form of Hathor as nursing Goddess of Thebes, was associated with this month, and the "birth of the harvest."

The final month of Shomu was called Mesore by the Copts, and Mesut-Ra, "Birthday of Ra," by the ancient Egyptians. The month was associated with Heru-iakhuti, or Re-Horakhty, Horus in the Horizon.

The key thing to keep in mind here is that the calendar was modeled on the Ideal cosmic order, where all three cycles came together and patterned the flood, planting, and harvest. The priesthood used their observations to ensure that the physical year cycle got tracked properly, but had no difficulty accepting that the calendar itself got out of synch with the manifest seasons. It's a very foreign concept to modern Westerners, but it actually tracks the real cycle of the year somewhat better than our system of leap years and intercalated corrections.
