Biblical Magi
The name of Gondophares was translated in Armenian in "Gastaphar", and then in Western languages into "Gaspar[d]". He may be the "Gaspar[d], King of Persia", who, according to apocryphal texts and eastern Christian tradition, was one of the three Biblical Magi who attended the birth of Christ. Through this interaction and association, Gaspar[d] was adopted by the Europeans (and in Western tradition) as a male first name.
