sculptor and architect.
His name appears frequently in the pontifical records. Between 1451 and 1460 he was employed on the triumphal arch of the Castel Nuovo at Naples (see Isaie da Pisa). About 1463 he made the statue of S. Andrea, which stands in a charming Doric shrine near the Ponte Molle, Rome.
February 17, 1451, Richier succeeded Jehan Roussel as maître de l'œuvre of the cathedral of Rouen. About 1458 he began the archbishop's palace at Rouen.
