The painting is a tronie, the Dutch 17th-century description of a ‘head’ that was not meant to be a portrait. It depicts a European girl wearing an exotic dress, an oriental turban, and an improbably large pearl earring.
To better understand the original function and context of the altarpiece, the exhibition includes a short documentary film about San Pier Maggiore – a church largely destroyed in the 18th century – using surviving archival, archaeological, and visual material. This film can also be viewed here.
