Ab

Semitic magical month. Crossing a river on the twentieth of that month was supposed to bring sickness. Ancient texts state that if a man should eat the flesh of swine on the thirtieth day of Ab, he will be plagued with boils.

Ab is also an ancient Egyptian term for the heart. Since the heart was the seat of the conscience, its preservation was a crucial part of the mummification process.
