Calixto
Calixto is known in Spain as the name of three popes, one of whom was the martyr, Calixtus I, regarded as a saint. Calixto has a lot of energy and futuristic spirit, thanks in part to the attention-grabbing ‘x.’ He is the main character in the Spanish classic, Fernando de Rojas’s Tragicomedy of Calixto and Melibea.
