This diploma thesis deals with the life and work of the Dutch painter Geertgen tot Sint Janse in the context of the beginning of Dutch Renaissance. This diploma thesis contains an analyses of Triptych with The Adoration of the Kings from the Prague Castle Collections. In particular, the art influences and the possible inspiration by the work of Albert van Ouwater is discussed. The Adoration of the Kings is an important piece of art not only in the context of Dutch Renaissance painting but also in the context of European Renaissance at the end of 15th century. The rich symbolic apparatus of the tryptich refers to the medieval tradition, but the beginning of illusionism can be recognised from the painting as well.
