Sancho de Larrosa (died 10 September 1142) was a Spanish ecclesiastic: a priest in the cathedral of Huesca, from 1101 to 1104 regent of the monastery of San Adrián de Sasabe and from 1122 until his death the bishop of Pamplona.
[1][2] In 1141, Sancho approved the creation of a Cluniac priory at San Adrián de Vadoluengo.
[3] Sancho was an accomplished scribe and miniaturist.
As a cathedral canon in Huesca, he composed documents for Bishop Stephen (1099–1130) in an elegant Caroline book hand.
[2] As bishop, he often accompanied his signature with a pictorial signum: the head of a bearded man.
