Lady Seated at a Virginal is a painting by Dutch artist Johannes Vermeer painted in approximately 1670–72. It shows a woman playing a virginal, with a viola da gamba depicted in the foreground, its bow between the strings. There is a painting depicted on the wall, which is either the original or a copy of Dirck van Baburen's The Procuress. It is one of several works by Vermeer featuring keyboard instruments, including The Music Lesson, The Concert, and Lady Standing at a Virginal. Scholars believe these may all be based on the same instrument, built by Johannes Ruckers. Lady Seated at a Virginal is in the National Gallery, London.Painting: Johannes Vermeer
