Henriette Marie (1626–51) of Paltz, daughter of Frederick V, King of Bohemia, nicknamed the 'Winter King'.

Cooper employed a delicate application of oil on cardboard, a material choice that allowed for a lightweight, portable object. The oval format and gold frame echo the design of contemporary portrait miniatures, while the soft modeling of the face and restrained palette align with mid‑17th‑century Northern European portrait conventions. Fine brushwork renders the hair and pearls with a luminous quality despite the modest support.

The portrait entered the Rijksmuseum’s holdings through acquisition in the early 20th century, though its earlier ownership remains undocumented. Its small size and locket‑like frame suggest it may have been used as a personal keepsake, possibly carried by family members during periods of exile following Frederick V’s brief reign as King of Bohemia.

Henriette Marie lived during a time of political upheaval; her father’s short rule earned him the nickname ‘Winter King.’ Portraits of royal children served both as affirmations of lineage and as portable symbols of dynastic continuity. Cooper’s work reflects this function, offering a discreet yet recognizable image of a princess whose family navigated exile and restoration.
