Pythagoras advocating vegetarianism, Peter Paul Ruben, 1618
Beasts settle hunger by means of meat, yet not all (do); Of course horses and livestock and herds (of oxen/cattle) live by means of grass, but those whose nature is savage and cruel, the Armenian tigers and hot-tempered lions, and bears with wolves, they rejoice with bloody feasts. Oh how much it is a crime that flesh is to be entombed by flesh and the gluttonous body to fatten, with a body having been ingested, and one living thing to live by the death of a living thing. Evidently, in how much the Earth, which is the best of mothers, brings forth for aid, nothing pleases you except to devour sad wounds by means of cruel teeth, and to repeat the ways of the Cyclops, that you will not be able to placate, having been delayed, the evil-natured hungers of your voracious stomach,unless you will have destroyed another.
Our bodies of ours also are always changing without any pause; What we were, or are, we will not be tomorrow. There was that day, on which we, only the seed and hope of man, were concealed by the womb of our first mother. Nature moved skillful hands and did not want the body, having been constructed, to be choked by the organs of the bulging mother, and sent it out from the home into the empty air. Having left, it laid in the light, speechless, without strength; Soon it carried the manner of quadrupeds, its own limbs (carried the manner) of beasts, and gradually, trembling and not yet with a firm knee, it stood, with every effort having been aided by muscles; From there, there was a swift and strong period of youth, and it passed, and also, with the years of middle time having been completed, it disappeared through the downward journey to fading old age. These (time periods) of life wear down and are destroyed before wood, and old Milon cries when he sees those insubstantial, soft arms to hang, which had been similar to the mass of firm muscle of Hercules. She cries also, as in the mirror she spied the wrinkles of an old woman, and asks why the offspring of Tyndaris (Helen) is twice taken. Time, devouring of all, and you, envious old-age, you will destroy everything, and with the the tainted teeth of time, gradually, slowly, you will consume all by means of death.
