Marie de France, from an illuminated manuscript now in the Bibliothèque nationale de France: BnF, Arsenal Library, Ms. 3142 fol. 256.
A woman is depicted standing and leaning slightly forward over an open book resting on an elegant white lectern with a decorative pedestal base. She wears a flowing pale cream or white robe that pools softly at her feet, with blue sleeves visible beneath, and a white veil or wimple covering her hair. Her face small, calm features with a downward gaze directed at the page. One hand reaches toward the open book as if reading or writing. The lectern stands on a terracotta-red bench or platform. Behind her, a trefoil arch frames the scene.
