his time, he painted with oil paint on wood panels. His paintings depict scenes derived from the New Testament and belong to the early Dutch School. Some of his paintings were destroyed during the Reformation. Around twelve surviving paintings are attributed to him (see below), with others believed to be copies by others of lost originals by him. Painting at that time was a trade to which one entered by apprenticeship at a young age in an established workshop. With modern techniques it is now possible to see some underdrawings that Geertgen made on his panels. Portrayal of music In his The Glorification of the Virgin, also known as Madonna with Musical Angels and originally part of the so-called Rotterdam-Edinburgh Diptych, the figures of Maria and the infant Jesus are surrounded by three concentric rings which appear to be surrounding a central halo. This "halo" is usually associated with the biblical verse in the Book of Revelation referring to the woman clothed in the Sun, interpreted as representing the Madonna in heaven. The original diptych was first presented with a left panel of identical size usually referred to as Geertgen's Passion of Christ. Within the concentric rings of the halo in the Madonna with Musical Angels panel are found a variety of musical instruments. This painting shows some of the oldest pictures of musical instruments known in the Netherlands (c.1480–1490). In the central depiction of the infant Jesus with the Madonna, the infant Jesus is depicted as playing a pair of bells, and seems to be playing music as if in response to one of the angels in the outermost concentric ring, holding an identical set of bells and looking directly back at the infant Jesus.
