Which Rembrandt painting portrays his son Titus wearing a monk’s robe?

Rembrandt’s painting portraying his son Titus wearing a monk’s robe is Titus as a Monk.

Rembrandt painted the work in 1660, when Titus van Rijn was about 19 years old. The portrait shows Titus in a dark habit-like garment and cap, with his face brightly illuminated against a subdued background. Its title describes the costume rather than identifying Titus as an actual monk.

Titus was Rembrandt’s only child with Saskia van Uylenburgh to survive infancy. He later helped manage his father’s affairs, particularly after Rembrandt’s financial collapse. Rembrandt made several portraits of Titus, who appears with a thoughtful, quiet expression in this work.

The painting is sometimes confused with other portraits of Titus, including works showing him as a young man in ordinary clothing. Its distinctive monastic costume is the key identifying feature.
