Master Mateo was a sculptor and architect who worked in medieval Christian kingdoms of the Iberian Peninsula during the second half of the twelfth century. He is best known now for the Pórtico de la Gloria of the Cathedral of Santiago de Compostela. He was also responsible for the stone choir of the cathedral in 1200, later torn down in 1603.
The earliest information about Maestro Mateo is from an 1168 document in the archives of the cathedral of Santiago, which says that the Master was already working on the Cathedral of Santiago de Compostela, for which he received a large sum of money from King Ferdinand II of León.
Very little information remains about his early training, but everything seems to imply that he already had a long career behind him all along the Way of Santiago, especially in the French sections.
