According to Egyptian mythology Seth (Osiris' brother) killed Osiris, and Horus, who was the son of Osiris, fought and killed Seth, but also lost his eye in the battle. Part of his "eye" were restored by the god Thoth.
Egyptians used fractions to measure grain and these fractions were parts of a hekat, which is the Egyptian unit measure for grain.
This is the only information I could find about it after reading parts of the books found in the "References" section below. I found it interesting how the God gave back his eye, as if he didn't deserve to lose it. The eye and its fractions are connected to grain, which is an important element of their sustainability, perhaps as a reminder of justice.
As for myself, I grew up in a superstitious household and culture and the number 13 scared me a lot, as it was supposed to bring bad luck. Even up to this day, whenever I see it I have to remind myself that it's just a number and it's all mysticism, and that it has nothing to do with the cause and effect of daily events.

Isn't it interesting how the Egyptians used fractions both to measure grain and to symbolize parts of a story about their gods.
ReplyDeleteYour post made me curious about the superstition connected to the number 13. It is a significant number in many cultures in some cases with connections to the time in a year that is in excess of 12 months.
