San Pablo was commenced by Cardinal Don Juan Torquemada, and completed in A.D. 1463.[80] It is said by some to be the work of Juan and Simon de Colonia, but I can find no proof of this statement, though I think that the elaborate façade may possibly be the work of the artists Gil de Siloe or Diego de la Cruz, who wrought under Juan de Colonia and his son at the monuments and Retablo in the convent at Miraflores. The first stone of the college of San Gregorio was laid in A.D. 1488, and it was finished in A.D. 1496.[81] The architect is said to have been Macías Carpintero of Medina del Campo; but as he cut his own throat in 1490,[82] some other architect or sculptor must have completed the work. The monastery of San Benito was founded by King Don Juan, who obtained a Bull from Pope Clement VII., on Dec. 28, 1389, for the purpose. But the existing church was erected more than a century later, by Juan de Arandia (probably a Biscayan architect), who began his work in A.D. 1499. He agreed to execute the nave and one aisle for 1,460,000 maravedis, and afterwards the other aisle for 500,000. The Retablo and the stalls were the work of Berruguete, between A.D. 1526 and 1532, and are now preserved in the museum. The college of Sta. Cruz was founded in A.D. 1480, and completed in A.D. 1492, and was designed by Enrique de Egas[83], son of Anequin de Egas of Brussels. The church of La Magdalena appears, by extracts from the archives of the Marquis de Resilla, to have been planned by Rodrigo Gil, of Salamanca. By a contract, dated June 14, 1576, he undertook the erection of the Capilla mayor and sacristy for 4,000,000 maravedis, whilst the “master of the works,” Francisco del Rio, by an agreement of October 11, 1570, agreed to build the tower and body of the church according to Rodrigo Gil’s plan, for 6400 ducats. Having given these details of their history, I must now say a few words about the buildings themselves.
