[1][2] Gerace probably owes its origin, or at least its importance, to the ruin of the town of Locri Epizephyrii, one of the earliest Greek colonies in Lower Italy, founded by the Ozolian Locrians (684–680 B.C.)

The town was in a favorable position for the exploitation of the rich fields along the coast of the Gulf of Taranto, and sharing in the commerce of the east-west trade route.

The Normans began the turn away from Greek affiliations toward Rome, aided by the policies of Gregory VII and Urban II.

The latter demanded as bishop the monk Bartenulfo, a Greek, whereas Pope Innocent IV, in 1253, appointed Marco Leone.

[10] Among the dignities were: the Cantor, the Archdeacon, the Archpriest, the Primicerius, the Dean, the Protonotary, the Treasurer, and the Master of Ceremonies[11] The seminary of the diocese was founded by Bishop Candido, in obedience to the decrees of the Council of Trent, and completed by his successor Bishop Pasqua.
