Ancient Egyptian Origins
Decans first appeared in the 10th Dynasty (2100 BCE) on coffin lids. The sequence of these star patterns began with Sothis/Sirius, and each decan contained a set of stars and corresponding divinities. As measures of time, the rising and setting of decans marked 'hours' and groups of 10 days which comprised an Egyptian year.
There were 36 decans (36 X 10 = 360 days). plus 5 added days to compose the 365 days of a solar based year. Decans measure sidereal time and the solar year is 6 hours longer; the Sothic and solar years in the Egyptian calendar realign every 1460 years. Decans represented on coffins from later dynasties (such as King Seti I) compared with earlier decan images demonstrate the Sothic-solar shift.

“Silent rushes the swift Lord
Through ruined systems still restored,
Broadsowing, bleak and void to bless,
Plants with worlds the wilderness;
Waters with tears of ancient sorrow
Apples of Eden ripe to-morrow.
House and tenant go to ground,
Lost in God, in Godhead found.”
—Ralph Waldo Emerson (1803–1882)

“Lucretius
Sings his great theory of natural origins and of wise conduct; Plato
smiling carves dreams, bright cells
Of incorruptible wax to hive the Greek honey.”
