Rubens found work as a lawyer among the many refugees in that city and was approached by
Anna of Saxony to help her recover some of her bridal dowry, which her husband's family had invested in their war on the
Duke of Alva. Anna and Rubens both had vested interests in the Southern Netherlands that they were attempting to salvage and perhaps they were living in close proximity. They had an affair which resulted in pregnancy. In March 1571, Rubens was arrested by members of the
Nassau family and taken to Dillenburg. On 22 August 1571, Anna of Saxony gave birth to their daughter, Christine von Dietz in
Siegen. Maria promptly moved to Siegen (about 35 kilometers from Dillenburg) and began to write letters of support to her husband, who thought at the time he might be put to death. She also wrote to various members of the Nassau family, including Anna's brother-in-law
Johann VI, Count of Nassau-Dillenburg. Rubens was allowed to join his family in Siegen on condition of payment of 6,000 daalders bail, but he was not allowed out of Siegen or do any business work until the death of Anna of Saxony in Dresden on 18 December 1577. ==Family==
