Seshet's name was interpreted as Sesheta
by Budge. Gardiner interprets the "t" as just a feminine ending so he calls her Sesha. She was originally associated with building plans and later with writing, books and Hathor.
I keep this Budge drawing of Seshet colored gold to remind myself of the wonderful golden photo of a wall relief featuring Seshet here on GeoCities at Michel Guntern's page. There you will notice the cow's horns on Hathor in the top scene and the inverted horns on Seshet below.
Seshet appears on tomb walls in the early dynasties, and she continues to appear in papyri through the Ptolemaic period, so she
knew the era of horses in Egypt during which the ancients became enamored
with the ancestors of our current Arabian horses.
I don't know if Nefertiti, our queen in her chariot below, paid attention to Seshet during that era in Armana honoring the Aton more than the other ancient dieties.
