The Jehovah's Witnesses adopted the Cerberus of mythology as a mascot?

Quote:

Cerberus was the offspring of Echidna, a hybrid half-woman and half-serpent, and Typhon, a fire-breathing giant whom even the Olympian gods feared. Its brother is Orthrus, always depicted as a two-headed hellhound.[10] The common depiction of Cerberus in Greek mythology and art is as having three heads, a mane of live serpents (similar to Medusa's hair) and a snake's tail. In most works the three-heads each respectively see and represent the past, the present, and the future, while other sources suggest the heads represent birth, youth, and old age.[11] Each of Cerberus' heads is said to have an appetite only for live meat and thus allow the spirits of the dead to freely enter the underworld, but allow none to leave.[12] Cerberus was always employed as Hades' loyal watchdog, and guarded the gates that granted access and exit to the underworld (also called Hades).[13]
