Guardian I ended up on a wiki about a little known (to us) Greek island called Gavdos. Read it here. I could not help noticing similarity between this Gavdos and my Gozo - particularly the Turkish rendition of the name to "Gondzo" and the story of Calypso Cave and Ogygia.
So the question now is... which Gozo/Gondzo/Gavlos was it? And more importantly will we build a bridge to Crete too?
