Background
Eustace was born in Burgundy and became a monk at Luxeuil.
Eustace was born in Burgundy and became a monk at Luxeuil.
He succeeded his teacher Saint Columbanus, to whom he had been a favourite disciple and monk.
"Saint Eustasius" is also the name of a bishop of Aosta. He had been the head of the monastic school. Subsequently Columbanus settled at Bobbio in Italy.
After the death of Thierry, Clothaire II sent Eustace to Bobbio to ask Columbanus to return, but he declined.
Under the administration of the abbot Eustace, the monastery acquired renown as a seat of learning and sanctity. Through the royal patronage, its benefices and lands were increased, King Clothaire II devoting a yearly sum, from his own revenues, towards its support.
Eustace and his monks devoted themselves to preaching in remote districts, not yet evangelized, chiefly in the north-eastern extremities of Gaul. Their missionary work extended even to Bavaria.
Between the monasteries of Luxeuil in France and that of Bobbio in Italy (both founded by Street Columbanus) connection and intercourse seem to have long been kept up.
During his abbacy, the monastery contained about 600 monks and produced both bishops and saints, including Amatus and Romaric. He was succeeded as abbott by Saint Waldebert. A tradition states that he cured Sadalberga of blindness.
He had been visiting Bavaria and cured this future saint of her ailment after stopping by at her house.
He is said to have also procured a cure for Saint Burgundofara. His feast day is March 29.
