Apparently Pythagoras Forbade His Followers to Eat Fava Beans

Pythagoras allegedly forbade his followers to eat beans. Beans were a common source of food for people and for grazing animals in the mediterranean at the time. The idea here would be that beans contain souls, potentially human souls. An orphic fragment puts it like this, eating beans and gnawing on the heads of one's parents are one and the same. To eat a bean is thus a form of murder.
