I always wanted to know what place the ram took in Egyptian mythology. Thanks to wikipedia I was able to find out.
Heryshaf was an Egyptian ram-god. The article in wikipedia is very interesting. Particularly interesting is that "one of his titles was “Ruler of the Riverbanks.” Heryshaf was a creator and fertility god who was born from the primeval waters. He was pictured as a man with the head of a ram, or as a ram."
Here is another good article.
It is interesting that Ramses II (who some identify as the Pharao of Yitziat Mitzrayim) is known to have expanded the temple of Heryshef.
