In the spring of 1917, during the blockade of Greece by the fleets of the Entente Powers, a pamphlet, of which a translation is given below, was published in Athens by one Georgios Papagiannakopoulos, describing the great miracle wrought by Saint Gerasimos on behalf of the island of Cephalonia, of which he is patron, at the expense of the admiral of a British fleet said to have then been anchored in the bay of Argostoli, the capital of the island.

Saint Gerasimos, who, like his brother Saint Dionysios of Zante, is of comparatively recent date, and Hosios (Beatus), not Hagios (Sanctus), was born of the great family of Notaras, at Trikala in the Morea, on August 15th, 1500. It is remarkable that two of the largest Ionian Islands should have chosen for their patrons modern saints sprung from great local families; for Saint Dionysios was a son of the house of Sygouros.
