To begin this quest you have to go to the Skyros island and release the Prisoner you will find in the Pirate Hideout. The bandits in the camp are drunk and will not disturb you.
As with all great adventures, Alexios's and Barnabas's started small. What began as a simple rescue quickly unfurled into an epic tale of gods, monsters, and ghosts from the past.
When you talk to the prisoner, drunk Barnabas will come up.
The pirates in the camp will sober up a little and attack you so you'll have to kill them.
When Barnabas sober up, he will tell you about the visions in which he saw his wife named Leda.
Hints:
To get the information you have to complete three support quests: Wine for the Swine, To Be Nobody and Beware the Siren Call. When you collect "cyclops's" spices, bracelet from Circe and the aulos, return to Barnabas and give him these items.
Rewards: Rare XP, Rare Drachmae.
