Modern musicologists have been able to recreate a working copy of the instrument. Until the Trecento, when the idea of orchestration was introduced, music playing angels were typically winged, depicted holding stringed or wind instruments as they hovered "on the wing" around on the edges of images of saints and deities. In French illuminated manuscripts of the first two decades of the 15th century, winged angels often seemingly floated on the margins of the page, as illustrations to the accompanying text.
