The miracle of the Holy Snakes of the Theotokos has occurred yearly with the exceptions of 1940 and 1953, when the island was hit by major earthquakes. People have taken the absence of snakes to be a sign of impending trouble for the nation.
The snakes have a small cross on their head and their tongues are also in the shape of a cross and show no fear during the feast. However, after the Liturgy on August 15, they become hostile and aggressive, disappear back into the wilderness, and can’t be found until the following year.
