For the first time in twenty-four years and only the second time in their history, two masterpieces of early Netherlandish painting commissioned by the Carthusian monk Jan Vos are reunited in this major new volume. These works, The Frick Collection's Virgin and Child with St. Barbara, St. Elizabeth, and Jan Vos, commissioned from Jan van Eyck and completed by his workshop, and The Virgin and Child with St. Barbara and Jan Vos (known as the Exeter Virgin, after its first recorded owner), painted by Petrus Christus and now in the Gemaldegalerie, Berlin, are examined with a selection of objects that place them in the rich monastic context for which they were created. This visually rich, scholarly volume explores the works' patronage, function, reception, and spiritual environment, offering a focused look at devotional practices in Bruges during the mid-fifteenth century.
