Focus on The Holy Kinship (Geertgen tot Sint Jans) and discuss the Provenance.
This painting is a former altarpiece of an unspecified church, though it is tempting to imagine similarities to the Commanderie van Sint-Jan where Geertgen is known to have lived and worked: Janskerk, Haarlem. The provenance of this painting only goes back to a Brussels sale in 1797 however, and indeed the painting was purchased in 1808 as a work by Jan and Hubert van Eyck. It wasn't until 1888 that it was identified as a work by the Haarlem master. Since then several attempts have been made to determine the origins of the painting. In his translated Schilder-boeck, Hessel Miedema reported that Geertgen died somewhere between 1486 and 1492, while recent dendrochronology, on the other hand, places the painting around 1496 at the earliest. The painting has many similar details in common with Albert van Ouwater's circa 1445 Lazarus and the tiled floor is similar to a contemporary painting by the Master of Alkmaar:
