The Marriage of Saint Catherine

Vanni employs a combination of black and red chalk, allowing for soft yet distinct line work. The folds of the woman's garment are rendered with swift, sketchy strokes that convey texture and movement, while the background is suggested through light, gestural marks that hint at stone and foliage without detailed modeling.

The drawing reflects Vanni’s broader involvement in late‑sixteenth‑century Italian printmaking and publishing, where such studies often preceded painted works. Although specific ownership records are limited, the piece is representative of Vanni’s dual role as draughtsman and printer, linking it to the workshop practices of his era.
