Rufinus was an Italian canon lawyer, described as the most influential canonist at the University of Bologna in the mid 12th century.[1] He composed a Summa on Gratian's Decretum before 1159,[2] which soon became the most influential commentary in Bologna, surpassing all previous ones in detail and length.[3]

Stephen of Tournai, his pupil, quoted from his Summa several times.[4]
