Surprising New Finds from Ancient Egyptian Star Charts

Planetarium software, among other things, shows how ancient Egyptians planned to navigate the sky after death

By Christine Gorman | Sep 15, 2015

Ancient Egyptians expected to be very busy in the afterlife. Thousands of years ago they painted big beautiful eyes on the outside of their coffins so that they could see what was going on in the world. Some of the nobility around the upper Egyptian city of Asyut even had detailed tables of star movements drawn on the inside of their coffins. The depictions look like timetables or spreadsheets of when various stars first appear (or disappear) over the horizon at different times of the year—only a lot more beautiful.

Scholars have long believed that the star charts represented a very early type of clock, for telling time at night, which might be important for certain religious rituals. But Sarah Symons of McMaster University in Ontario thinks it more likely that the tables represent a kind of map for the dead to properly navigate the sky, where they would live forevermore as stars. Her conclusions are based on years of research into ancient Egyptian beliefs, extensive surveys of the 27 known star tables or fragments of tables in the world and, using planetarium software, the ability to easily recreate the nighttime sky as it appeared more than 4000-odd years ago along the Nile. Symons and co-author Elizabeth Tasker of Hokkaido University in Japan describe the work in the October issue of Scientific American.

The basic layout of the star charts has, of course, been known for decades, as Symons and Tasker write in "Stars of the Dead." A complete table "is divided into quarters by a horizontal and a vertical strip. The horizontal strip contains a line from a religious text making an offering to a number of Egyptian gods, and the vertical strip pictures four images of the gods themselves. . ."
