The saint behind the name
Elesa of Kythira
August 1, Martyr, Ελέσα
St. Elesa was a virgin martyr honored by tradition as the patroness of the island of Kythira. Her very birth was an answer to prayer: her mother, a pious Christian who had long struggled to bear a child, prayed fervently and received the divine assurance that God had shown her mercy — in Greek, ho Theos elesese — and so the daughter granted to her was named Elesa. Raised by her mother in the faith despite her pagan father, she embraced Christ and consecrated her life to Him. When her father raged against her faith she fled across the water to Kythira; pursuing her there, he put her to death, and she received the crown of martyrdom in her youth.
