Elaine Pagels is the first to claim that in 367, Athanasius ordered monks in the Coptic Orthodox Church of Alexandria in his role as bishop of Alexandria to destroy all "unacceptable writings" in Egypt, the list of writings to be saved constituting the New Testament. While there is no evidence that Athanasius decreed all unacceptable writings to be burned, this unsubstantiated claim by Pagels is frequently cited as fact on the internet. The Sibylline Books were a collection of oracular sayings. According to myth, the Cumaean sibyl offered Lucius Tarquinius Superbus the books for a high price, and when he refused, burned three. When he refused to buy the remaining six at the same price, she again burned three, finally forcing him to buy the last three at the original price. The quindecimviri sacris faciundis watched over the surviving books in the Temple of Jupiter Optimus Maximus, but could not prevent their being burned when the temple burned down in 83 BC. They were replaced by a similar collection of oracular sayings from around the Mediterranean in 76 BC, along with the sayings of the Tiburtine sibyl, and then checked by priests for perceived accuracy as compared to the burned originals. These remained until for political reasons they were burned by Flavius Stilicho (died 408). In 385, the theologian Priscillian of Ávila became the first Christian to be executed by fellow-Christians as a heretic. Some (though not all) of his writings were condemned as heretical and burned. For many centuries they were considered irreversibly lost, but surviving copies were discovered in the 19th century. "Etrusca Disciplina", the Etruscan books of cult and divination, were collected and burned in the 5th century. The books of Nestorius, declared to be heresy, were burned under an edict of Theodosius II(435). The Greek originals of most writings were irrevocably destroyed, surviving mainly in Syriac translations. Patriarch Eutychius of Constantinople published a treatise, on the General Resurrection, maintaining that the resurrected body "will be more subtle than air, and no longer palpable". Pope Gregory the Great opposed, citing the palpability of the risen Christ in . As the dispute could not be settled, the Byzantine emperor, Tiberius II Constantine, undertook to arbitrate. He decided in favor of palpability and ordered Eutychius' book to be burned.
