A portrait of da Montefeltro (with his broken nose in profile) in the company of Caterino Zeno, a Persian envoy to the court of Urbino, is included in the picture.
This included a commission for a portrait series of 'uomini famosi' (famous men) for the study of da Montefeltro (Louvre Museum, Paris and Galleria Nazionale, Urbino).
[3] Two works from the time before he left for Italy have been preserved: the monumental Crucifixion Altarpiece or Calvary Triptych (in the Saint Bavo Cathedral, Ghent) and the Devotion of the Kings (Metropolitan Museum of Art, New York).
The stage-like space and arrangement of the main figures in two parallel diagonal lines seem to suggest an inspiration by theatre reenactments of the story of the Epiphany.
The Institution of the Eucharist,[5] sometimes called The Last Supper) for the Confraternity of Corpus Domini in Urbino shows some adaptations from the characteristically Netherlandish high viewpoint and decoratively organized surface of the Calvary Triptych.
An enlarged version of the Communion of the Apostles shows that Jesus Christ is depicted with light rays originating from his head which is also surrounded by a circular aureola both of which constitute a halo.
A series of 28 portraits of Famous men, which are still in existence and part of the collections of the Louvre and the Galleria Nazionale delle Marche in Urbino, have been attributed to Joos van Wassenhove.
Technological examination of the Famous men has revealed similarities of these works with the other important earlier commission that van Wassenhove completed for the duke in Urbino, i.e. the Communion of the Apostles.
