or retablo, retablum. Spanish term to indicate a particular type of altar frontal only in part identifiable with the term altar-piece, given that according to a well-documented local tradition, the retable is characterized by the presence of paintings and/or sculptural reliefs, including one or more levels in architectural frames, and placed on structures of particular monumentality. Although originally in Spain, this particular altar frontal is also documented in other European regions (France, Flanders, Germany and Austria) and, particularly in Latin America.
