Spanish term for a type of intricately joined wooden ceiling in which supplementary laths are interlaced into the rafters supporting the roof to form decorative geometric patterns (see fig.). Artesonado ceilings were popular in the Islamic architecture of North Africa and Spain from the 13th to the 15th century and were also used widely in Jewish and Christian architecture. They continued to be popular into the 16th century when they were effectively integrated with Renaissance motifs.
Artesonado ceilings developed from horizontal coffered ceilings, which were used in Spanish Islamic architecture as early as the 10th century
