Greek folklore abounds with tales of the undead, the vrykolakes who are said to be particularly prevalent in the area around the volcanic island of Santorini, called by some "Island of the Vampires"...The island of Santorini has been long renowned by the Greeks themselves as the final resting place of many suspected vampires, since the populace of the island was believed to be particularly adept in dealing with the undead.
Nearby islands would bring the remains of suspected vampires to Santorini for proper, permanent disposal. The dark banded cliffs created by the ancient eruption and the stark, almost lunar landscape of the Kamenes, the small islands of the caldera, help create a certain eerie atmosphere where such superstitions seem more reasonable. When the wind is right a faint sulphurous scent whispers of the nearness of the underworld. Today, various unofficial "vampire" events are held throughout the summer months.
And no, Greek vampires were not at any particular disadvantage from the blazing Greek sunlight. In this part of the world, demonic creatures are believed to be powerful not only at midnight, but at midday as well. Anyone who has been caught in a traditional village during the heat of the day is probably convinced of the supernatural powers of the inhabitants, all of whom seem to disappear until cooler temperatures coax them out again.
