Jan Rubens (/ˈruːbənz/; Dutch: [ˈrybəns]; 1530–1587) was a Flemish lawyer and city administrator of Antwerp, then located in the Spanish Netherlands.A convert to Calvinism, he fled Antwerp with his family because of the suppression of Protestantism in the Spanish Netherlands and settled in Cologne.Rubens is considered to be the natural father of Christine von Diez [de], the daughter of Anna of Saxony, who was born in Siegen in 1571.In 1566 the Low Countries were the victim of the iconoclasic fury, referred to in Dutch as the Beeldenstorm during which Catholic art and many forms of church fittings and decorations were destroyed in mob actions by Calvinist Protestant crowds.[3] In Cologne he could renew his work as a lawyer, because there were many Flemish and Dutch refugees there who wanted to recover seized property they had left behind.[4] When the affaire was discovered, Rubens was arrested during a trip he took to Siegen to visit her and he was locked up in the Nassau family's castle at Dillenburg in March 1571.The travel ban imposed on Jan Rubens was lifted in 1578 on condition that he not settle in the Prince of Orange's possessions nor in the hereditary dominions of the Low Countries and maintain the bail bond of 6,000 thalers as security.His widow Maria Pypelinckx returned with the rest of the family (i.e. Blandina, Philip and Peter Paul) to Antwerp in 1590, where they moved into a house on the Kloosterstraat.
