craftsmen took on all manner of woodwork, from ceilings to furniture. They were known for their skill in carpintería de lo blanco
(structural woodwork), leaving some of the most genuine creations in Spanish art: wooden ceilings and doors made of square-cut, ornately decorated wood that is constructed and decorated on the basis of a geometric pattern. Mudejar
mastery in this field can be seen in the perfect combinations of decoration and structure.
