The Book of Hours of Engelbert of Nassau (Bodleian Library, Oxford, MSS. Douce 219–220) is a book of hours in the Dominican Rite, illuminated by the Master of Mary of Burgundy, which was produced in Ghent in the 1470s or 1480s for Engelbert II of Nassau.[1] It is regarded as one of the high-points of Flemish manuscript illumination.
