Pompeia of Langoat

Saint Pompeia (in Latin: Alma Pompeia or in Breton: Koupaia ), also known as Aspasia, is a legendary Breton saint who supposedly lived in the 6th century. Her feast day is celebrated on 2 January.

Legendary biography
According to the life of her son, Tudwal, Pompeia was the sister of King Riwal II of Domnonée. Tradition at Langoat further asserts that she became one of the wives of the fictional King Hoel Mawr (or the Great) who was invented by Geoffrey of Monmouth as a supposed overlord of all Brittany. After being exiled in Britain for some years, Pompeia eventually returned to her husband's kingdom with her daughter, Saint Scaeva, and her son, Saint Tudwal. She settled near the monastery of Tréguier, founded by the latter, and died where the church of Langoat stands today. Her relics are still preserved there and a shrine has been erected to her memory.

Family
Saint Pompeia was the mother of:
 * Saint Tudwal: one of the seven founding saints of Brittany

Breton legacy

 * Sainte-Sève: Saint Scaeva's Church there contains a statue of Saint Pompeia; the name of the locality, Trébompé, probably stems from a corruption of the name Pompeia.
