Cambridge, Massachusetts: Harvard University Press, 2009. The later Vatican Mythographers repeat and expand upon the traditions of Servius and Fulgentius. All three Vatican Mythographers repeat Servius' derivation of Cerberus' name from creoboros. [154] The Second Vatican Mythographer repeats (nearly word for word) what Fulgentius had to say about Cerberus, [155] while the Third Vatican Mythographer, in another very similar passage to Fugentius', says (more specifically than Fugentius), that for "the philosophers" Cerberus represented hatred, his three heads symbolizing the three kinds of human hatred: natural, causal, and casual (i.e. accidental).

Cerberus had several multi-headed relatives. His father was the multi snake-footed Typhon, [11] and Cerberus was the brother of three other multi-headed monsters, the multi-snake-headed Lernaean Hydra; Orthrus, the two-headed dog that guarded the Cattle of Geryon; and the Chimera, who had three heads: that of a lion, a goat, and a snake. [12] And, like these close relatives, Cerberus was, with only the rare iconographic exception, multi-headed. Lightfoot, J. L. Hellenistic Collection: Philitas. Alexander of Aetolia. Hermesianax.

Online version at the Perseus Digital Library In the rationalized account of Philochorus, in which Heracles rescues Theseus, Perithous is eaten by Cerberus. [149] In this version of the story, Aidoneus (i.e., "Hades") is the mortal king of the Molossians, with a wife named Persephone, a daughter named Kore (another name for the goddess Persephone) and a large mortal dog named Cerberus, with whom all suitors of his daughter were required to fight. After having stolen Helen, to be Theseus' wife, Theseus and Perithous, attempt to abduct Kore, for Perithous, but Aidoneus catches the two heroes, imprisons Theseus, and feeds Perithous to Cerberus. Later, while a guest of Aidoneus, Heracles asks Aidoneus to release Theseus, as a favor, which Aidoneus grants. Ovid, Metamorphoses 7.413–419, which has Cerberus brought up from the underworld through a cave on "the shores of Scythia, where, 'tis fabled, the [aconite] plant grew on soil infected by Cerberian teeth." In 1965 Demikhov attended a medical conference where he proposed the creation of a bank where human organs could be stored for the needs of surgeons. The futuristic proposal, unthinkable at the time, sparked much anger among Soviet academics who criticized Demikhov and demanded the closure of his laboratory.
