What does Erasmus mean?
Latinized from the Greek Erasmos 'beloved, desired', related to erasmios 'lovely, pleasant', from the verb eran 'to love' (the same root as Eros). Best known from the humanist Desiderius Erasmus.
What does Python mean?
Greek Python, the great earth-serpent/dragon of Delphi slain by Apollo. Flag: this is the NAME OF a mythological serpent, not a word meaning 'serpent'; it is usually tied to the place-name Pytho and the verb pythein 'to rot' (folk-etymologized from the creature's rotting body), so the serpent association is mythological, not a literal translation.
