What does Ladon mean?
Greek Ladon, the serpent-dragon coiled around the tree of the golden apples of the Hesperides. Flag: a mythological dragon's NAME, not a literal 'dragon' word; its etymology is uncertain (one guess links it to a root 'to flow strongly', and Ladon is also the name of a river-god), so it is included as the name of a dragon.
What does Georgios mean?
Greek form of George, from 'georgos' ('farmer, husbandman'), itself from 'ge' ('earth') and 'ergon' ('work'). Borne by Saint George.
