CALCAS, CALKAS is Criseyde's father in Troilus and Criseyde. As Apollo's priest he is skilled in "calkulynge," Tr I.71; Tr IV.1398, and "calculating" gives some indication of his character. Susan Schibanoff points out that Calcas is one of the redendenamen or "speaking names" of medieval etymology, that is, a name that provides an interpretation of a character.
