Triptychon

This Triptychon, attributed to Pieter Coecke van Aelst and dated 1550, represents the final phase of his workshop production before his death in December of that year. A triptych of this period on canvas rather than panel — the medium noted in the record — suggests either a later copy or a specific commission that favored the more portable support. Coecke died leaving a workshop that his widow Mayken Verhulst would continue to direct, and his designs and compositional formulas remained in use for years after his death, making precise attribution of late works challenging. The triptych format, though somewhat archaic by 1550 in Italian terms, remained standard for Catholic devotional painting in the Low Countries and Spain throughout the sixteenth century. The lack of a specified collection for this work suggests it may be in private hands or awaiting institutional attribution.

Oil on canvas production required a different preparation sequence than panel: the fabric support needed multiple ground layers (often chalk mixed with animal glue, then oil-based priming) before paint could be applied. Canvas allowed larger formats than were practical in panel painting, though for triptych formats the practical requirements of hinging and portability typically kept the wings to manageable dimensions.
