What does Theodosius mean?
From Greek Theodosios, combining theos 'God' + dosis 'giving/gift' — 'given by God' or 'gift of God'. Shares its elements with Dositheus in reversed order.
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.
