What were the names of the criminals crucified along with Christ?

In Christian tradition, Saint Dismas (sometimes spelled Dysmas or only Dimas, or even Dumas), also known as the Good Thief or the Penitent Thief, is the "good thief" described in the Gospel of Luke. This unnamed thief, crucified alongside Jesus, repents of his sins, and asks Jesus to remember him in his kingdom. The name Dismas for this thief dates back to the 12th century, and various traditions have assigned him other names. Gestas, also spelled Gesmas, is the apocryphal name (first appearing in the Gospel of Nicodemus) given to one of the two thieves who was crucified alongside Jesus. According to legend, Gestas taunted Jesus about not saving himself, while Dismas asked for mercy. Dismas was saved, and Gestas was not.
