Benedict X
Antipope
Years: 1015 - 1080
Pope/Antipope Benedict X (died 1073/1080), was born Giovanni, a son of Guido (the youngest son of Alberic III, Count of Tusculum), a brother of the notorious Pope Benedict IX (deposed in 1048), a member of the dominant political dynasty in the region at that time.
He reportedly later was given the nickname of Mincius (thin) due to his ignorance.
