[spa] Abordamos el estudio estilístico e iconográfico de un conjunto de tablas de los siglos XV y XVI procedentes del Real Monasterio de Santa Clara de Úbeda y vendidas en la década de 1920 con la intervención del anticuario Celestino Dupont. Completamos este análisis con la fortuna crítica de estas piezas y sus vicisitudes posteriores una vez introducidas en el activo circuito del mercado de arte.

This collection was sold in the 1920s with the participation of the antique dealer Celestino Dupont. The research is complemented by an analysis of the critical appraisals given to these works and their history since their introduction into the art market.
