Peregrinus Proteus (; c. 95 – 165 AD) was a Greek Cynic philosopher, from Parium in Mysia. Leaving home at a young age, he first lived with the Christians in Palestine, before eventually being expelled from that community and adopting the life of a Cynic philosopher and eventually settling in Greece. He is most remembered for committing suicide after giving his own funeral oration, cremating himself on a funeral pyre at the Olympic Games in 165. By 180 AD, a statue of Peregrinus had been erected in his home city of Parium; it was reputed to have oracular powers. Life Lucian's satirical biography The only detailed account of the life of Peregrinus was recorded by Lucian in his satire, The Death of Peregrinus (). Although this account is hostile to Peregrinus, the bare facts of his life can be extracted. Peregrinus was born in Parium, c. 95 AD. At a young age he was suspected of parricide, and was obliged to leave his native home. During his wanderings he reached Palestine, he came into close contact with the Christian community, and quickly rose to a position of authority. He suffered a term of imprisonment at the hands of the Roman authorities, during which the Christians gave him much aid. He may have expected to be martyred, but the Governor of Syria released him. He seems to have become a Cynic at this point, because he returned home and renounced his inheritance, giving away all his money to the people of his home city. He resumed his wandering life, maintaining close relations with the Christians at first, but eventually he offended them in some way, and was expelled from the Christian community. He went to Egypt to study with the famous Cynic Agathobulus, where he learned the harsh asceticism of the sect. He made his way to Rome, where he began a campaign of abuse against the Roman authorities, and especially the emperor Antoninus Pius. He gained a following among the masses, and it may be at this point that Theagenes became his chief disciple. Although tolerated at first, he was eventually expelled by the City Prefect. He next went to Elis in Greece, where he continued his anti-Roman preaching. At the Olympic games (either 153 or 157), Peregrinus abused the wealthy philanthropist Herodes Atticus, whereby the infuriated crowd attacked Peregrinus, and he was forced to take refuge at the altar
