The followers of Pythagoras (called Pythagoreans) did not always practice strict vegetarianism, but at least their inner circle did. For the general public, abstention from meat was a hallmark of the so-called "Pythagorean way of life". Both Orphics and strict Pythagoreans also avoided eggs and shunned the ritual offerings of meat to the gods which were an essential part of traditional religious sacrifice. In the 5th century BC the philosopher Empedocles distinguished himself as a radical advocate of vegetarianism specifically and of respect for animals in general. A fictionalized portrayal of Pythagoras appears in Book XV of Ovid's "Metamorphoses", in which he advocates a form of strict vegetarianism. It was through this portrayal that Pythagoras was best known to English-speakers throughout the early modern period and, prior to the coinage of the word "vegetarianism", vegetarians were referred to in English as "Pythagoreans".
