Portrait of an old woman in a white cap

This 1641 portrait of an old woman in a white cap at the National Museum in Warsaw is an early character study in the Rembrandtesque tradition. The white cap, a common headdress for elderly Dutch women, provides a luminous accent against the darker tones of the costume and background. Ferdinand Bol was one of Rembrandt's most talented pupils, and his portraits and history paintings from his years in the master's studio are sometimes difficult to distinguish from Rembrandt's own work—a testament to his exceptional skill in absorbing the master's technique.

The white cap creates a bright focal point in the composition, its crisp fabric contrasting with the aged features and darker clothing in a study that demonstrates Bol's early mastery of Rembrandtesque technique.
