St Catherine disputing with the grammarians before the Emperor Maxentius

A pen, ink and grey wash drawing of St Catherine, standing in the centre, arguing in front of the Roman emperor Maxentius against the rhetoricians gathered in the court by the emperor to defeat her phillsophical views on Christianity. The emperor Maxentius is seated on his canopied throne on the left; the grammarians, or the rhetoricians, surround both the emperor and St. Catherine, while some are seated on the floor in the foreground. Immediately above her head, a bird is hovering in the smoke billowing in the background. The paper is partly squared/gridded.
