The ancient Egyptian goddess of the sky: How a researcher used modern astronomy to explore her link with the Milky Way

What did our ancestors assume once they regarded up on the night time sky? All cultures ascribed particular that means to the sun and the moon, however what concerning the pearly band of sunshine and shadow we name the Milky Way?

My current examine confirmed an intriguing hyperlink between an Egyptian goddess and the Milky Way.

Slowly, students are placing collectively a picture of Egyptian astronomy. The god Sah has been linked to stars within the Orion constellation, whereas the goddess Sopdet has been linked to the star Sirius. Where we see a plow (or the big dipper), the Egyptians noticed the foreleg of a bull. However the Milky Way’s Egyptian title and its relation to Egyptian tradition have lengthy been a thriller.

A number of students have suggested that the Milky Way was linked to Nut, the Egyptian goddess of the sky who swallowed the sun because it set and gave beginning to it as soon as extra because it rose the following day. However their makes an attempt to map totally different elements of Nut’s physique onto sections of the Milky Way have been inconsistent with one another and did not match the traditional Egyptian texts.

In a paper printed within the Journal of Astronomical History and Heritage, I in contrast descriptions of the goddess within the Pyramid Texts, Coffin Texts, and the Guide of Nut to simulations of the Milky Way’s look within the historic Egyptian night time sky.

Carved onto the partitions of the pyramids greater than 4,000 years in the past, the Pyramid Texts are a set of spells to assist the kings’ journey to the afterlife. Painted on coffins a couple of hundred years after the age of the pyramids, the Coffin Texts have been the same assortment of spells.

The Guide of Nut described Nut’s position within the solar cycle. It has been present in a number of monuments and papyri, and its oldest model dates again some 3,000 years in the past.

The Guide of Nut described Nut’s head and groin because the western and japanese horizons, respectively. It additionally described how she swallowed not solely the sun but in addition a sequence of so-called “decanal” stars that are thought to have been used to inform time in the course of the night time.

From this description, I concluded that Nut’s head and groin needed to be locked to the horizons in order that she might give beginning and later swallow the decanal stars as they rose and set all through the night time. This meant that she might by no means be mapped instantly onto the Milky Way, whose totally different sections rise and set as effectively.

I did, nonetheless, discover a doable hyperlink to the Milky Way within the orientation of Nut’s arms. The Guide of Nut describes Nut’s proper arm as mendacity within the northwest and her left arm within the southeast at a forty five diploma angle to her physique. My simulations of the Egyptian night sky utilizing the planetarium software program Cartes du Ciel and Stellarium revealed that this orientation was exactly that of the Milky Way in the course of the winter in historic Egypt.

The Milky Way is just not a bodily manifestation of Nut. As a substitute, it could have been used as a figurative strategy to spotlight Nut’s presence because the sky.

Throughout the winter, it confirmed Nut’s arms. In the summertime (when its orientation flips by 90 levels) the Milky Way sketched out her spine. Nut is usually portrayed in tomb murals and funerary papyri as a unadorned, arched lady, a portrayal that resembles the arch of the Milky Way.

Nonetheless, Nut is also portrayed in historic texts as a cow, a hippopotamus and a vulture, thought to spotlight her motherly attributes. Alongside the identical strains, the Milky Way may very well be considered highlighting Nut’s celestial attributes.

The traditional Egyptian texts additionally describe Nut as a ladder or as reaching out her arms to assist information the deceased as much as the sky on their strategy to the afterlife. Many cultures all over the world, such because the Lakota and Pawnee in North America and the Quiché Maya in Central America, see the Milky Way as a spirits’ road.

The Guide of Nut additionally describes the annual chook migration into Egypt and ties it each to the netherworld and to Nut. This part of the Guide of Nut describes Ba birds flying into Egypt from Nut’s northeast and northwest sides earlier than turning into common birds to feed in Egypt’s marshes.

The Egyptians thought of the Ba, portrayed as a human-headed chook, to be the side of an individual that imbued it with individuality (related, however not an identical, to the trendy Western idea of the “soul”).

The Bas of the useless have been free to go away and return to the netherworld as they wished. Nut is usually proven standing in a sycamore tree and offering meals and water to the deceased and their Ba.

As soon as once more, a number of cultures throughout the Baltics and northern Europe (together with the Finns, Lithuanians, and Sámi) view the Milky Way as the trail alongside which birds migrate earlier than winter. Whereas these hyperlinks do not show a connection between Nut and the Milky Way, they present that such a connection would place Nut comfortably inside the world mythology of the Milky Way.
