apotheosis

[Lucius Tyrrhenus Garrulus]

SALVETE OMNES!
I'm trying to understand the process of apotheosis in Roman religion. As it is a Greek word, maybe the Collegium Graecum could help me...
What is exactly needed for apotheosis to take place? A God/dess presents a mortal to the Gods, they accept the mortal, then the mortal becomes a God? Is that how it happens?
Also, in Greek mythology, is Herakles the only person this happened to?
MVLTAS GRATIAS VALETEQVE BENE!

[Horatius Piscinus]

Salve Garrule

Another mortal at the Olympian banquet tables would be Ganymede. There are others. I forget his name now, but one goddess had a mortal granted immortality but neglected to ask that he never grow old. And then there is Adonis, the boy-toy shared by Persephone and Aphrodite who later became a god. Hercules's story was taken as a metaphor for all mortals, in some schools of philosophy, whereby all mortals can achieve apotheosis by their deeds. The process by which this was achieved I think would be explained differently among the schools of philosophy.
