What is "olegarius"

Saint Olegarius Bonestruga (from Germanic Oldegar, , , ; 1060 – 6 March 1137) was the Bishop of Barcelona from 1116 and Archbishop of Tarragona from 1118 until his death. He was an intimate of Ramon Berenguer III, Count of Barcelona, and often accompanied the count on military ventures.

Olegarius was canonised in 1675 and his major shrine and sepulchre is in the side chapel of Christ of Lepanto in the cathedral of Barcelona. His feast is celebrated the date of his death: March 6. An unreliable vita was composed for his canonisation, based on a fourteenth-century Vitae sancti Ollegarii, which is based on a lost twelfth-century vita often ascribed to Olegarius' contemporary of Barcelona, Renald the Grammarian.
