# Hecatomb

.It is said that Pythagoras offered up 100 oxen to the gods when he discovered that the square of the hypothenuse of a right-angled-triangle equals both the squares of the other two sides. This is the 47th of book i. of “Euclid,” called the dulcarnein (*q.v*.). But Pythagoras never
sacrificed animals, and would not suffer his disciples to do so.
