Quiricus (died January 680) was the metropolitan bishop of Toledo from about 667 until his death. He may be identical to Bishop Quiricus of Barcelona, who does not appear as bishop there after 667. If so, his transfer to Toledo was contrary to canon law, but would demonstrate the growing importance of Toledo in the Visigothic church.
In 672, in accordance with the tenth canon of the Eighth Council of Toledo, Quiricus anointed the duly elected Wamba after the death of Reccesuinth. In 675 he presided over the Eleventh Council of Toledo. In 681 the ecumenical Third Council of Constantinople repudiated monothelitism and affirmed the doctrine of dythelitism, that Christ had two wills. A decision of the council was sent to Quiricus, but he had died by the time it reached Spain.
Quiricus , a churchman and well-connected man of letters, was the bishop of Barcelona from 648 until about 667 during the Visigothic period.
Quiricus wrote a hymn in honour of Saint Eulalia. The hymn Barchinon laete Cucufate vernans, in honour of Saint Cucuphas (Cugat), was probably also composed by him. At Quiricus' request, Taio, Bishop of Zaragoza, began compiling an anthology of extracts from the work of Gregory the Great in 653. In 654, progress on the compilation was slowed by the revolt of Froia and the invasion of the Basques. Archbishop Ildefonsus of Toledo dedicated his treatise on the perpetual virginity of Mary (De perpetua virginitate) to Quiricus.
Quiricus of Barcelona may be identical to the Quiricus of Toledo who appears as bishop there from about 670 until his death in 680.
