In a medieval charter from the year 1435 a house was mentioned as being located in a place known as the Joderye. This is as far as known the first “hard” evidence of Jewish presence in Utrecht.
The origin of these Jews is not known, but a relation with the expulsion of the Jews from Cologne in 1424 is rather probable, even though some of the Jews from Cologne settled in the nearby Deutz..
Images of Jews from approximately the same period are shown in the booklet (frontpage and 2. Karel V, the Church, and the expulsions). As the painting and the reliefs served in part to show the distinctness of the Jews the images may contain stereotypical elements and deviate from “reality”.
The Utrecht Archive – Entry 709 No 1363 and 1305/1-3: An agreement between a certain Steven Boen and his wife Uedel with the St.Barbara and St.Laurens Hospital in which they are allowed to stay in the house (1435) and later legate their belongings to the hospital (1438-1443)
