Blessed Sebastian, the son of a noble family, was born at Brescia, Italy, in 1414 and entered the Order in 1429. Twice he was Vicar General of the reformed Province of Lombardy and served as prior in several convents. He was severe in his personal life, but kind and patient in his dealings with others. He was one of the notable reformers of Dominican life in the fifteenth century. He died at Genoa at the monastery of Santa Maria di Castello in 1496.
