"The Mystic Marriage of St. Catherine"

Óbidos, whose father owned a large collection of prints which they both copied, is believed to have taken this composition from a 1528 painting by Titian that would have been known to her from a 1565 engraving, which explains why her version is the reverse of Titian's. She produced at least four small works on copper of the same subject, which indicates that this was likely an exercise in repetition in order to improve her skills, and/or a form of proof of her strong talent as a teen. Her rendering of faces, and her inclusion of still life elements such as the basket at the bottom left of the frame)shows the influence of Francisco de Zurbarán, with whom her father had studied in Seville.  Óbidos showed particular aptitude in rendering exquisite detail (such as on the dress and rug) on this miniature scale.
