Lorenzo de San Nicolás
Fray Lorenzo de San Nicolás was a Spanish architect. As he was a member of a religious order, he was known by the Spanish language title "fray".
Born in Madrid, his double career as an architect and a friar began in his teens. He was influenced by his father who was also an architect and, in later life, an Augustinian friar.
He wrote and published Arte y Uso de la Arquitectura, in two tomes, an influential book in baroque Spain and Spanish America of the X17th and 18th centuries.
