The objects of iron-work made by the Christian artists of this period in Spain must have been good, for although no specimens exist, we have at any rate historical information which confirms this. In the Consistorial Ordinances of Barcelona, Capmany, "Memoirs," vol. i., we find that ironsmiths formed an extensive guild in the 13th century; in 1257 four of its members formed part of the chief municipal council; this guild increased in importance in the following centuries. The Ordinances of Seville of the 15th century, which were reformed in 1502, and those of Toledo, also re-enforced in 1582, give an idea of what was done by workers in bronze, the methods of workmanship and other details of interest. The Ordinances of Seville mention _rejas_ made in Biscay, and give a good idea of the styles adopted by the iron-masters there. The Ordinances of Granada repeat almost exactly the former prescriptions. The Cathedrals and large churches in Spain lent themselves in an admirable manner to the construction of objects of all kinds in iron work, especially the railings enclosing the side chapels, or sepulchres, and the double screens required for the _Capilla Mayor_ and _Coro_, owing to the ancient Spanish custom of constructing the choir in the centre of the principal nave of the cathedral. Hence we meet with names of the iron-masters, _rejeros_, mentioned in early documents as attached to the different cathedrals in the same manner as painters and architects. We find Bartolomé Morey working at Palma de Mallorca in 1389 to 1397. He was succeeded by his son Juan, from 1401 to 1407. See Piferrer, "Recuerdos y Bellezas de España." Maestro Basil worked at Burgos, and Maestro Pablo at Toledo and its dioceses towards the end of the same century. Maestro Juan Francés worked at Toledo in 1482. By this same artist is the beautiful _reja_ of the Capilla Mayor of the _Colegiata_ of Alcala de Henares; it is signed, "Maestre Juan Francés, maestro mayor de las obras de fierro en España." From this time the names of iron-masters are well known and numerous; we may safely affirm that those who lived in the 16th century have left us the most important works.
