Maria Thins

Thins had three children, the youngest of whom was Catharina Bolnes (c. 1631–1688), nicknamed Trijntge.[11][12] She also had a son Willem,[13] and a daughter Cornelia.[7] Around 1635, Reynier became verbally and physically abusive with her and her children.[4][7] At the age of nine, Catharina ran to neighbors because she thought that Reynier's abuse of Cornelia could kill her. Reynier confessed that he physically abused Cornelia and would do it again if Thins beat their son Willem. Reynier and Willem began eating separately from the female members of the family, and the father encouraged his son to be abusive and noncompliant with Thins.[14]

Thins moved to Delft in 1642 to get away from her abusive husband. Jan Geensz Thins, who was her guardian and cousin, purchased a home for her there the prior year.[3][15] Jan became Thin's guardian following the early death of her father.[6] Thins attained custody of her daughters in 1641 and moved with them to Delft. William stayed with his father, whose business began to fail.[15] Thins lived on Oude Langendijk next to the Jesuit Catholic Church[2] in the Catholic section of Delft called paepenhoek (the Papists' Corner).[6][16]

Thins received half of her husband's assets,[10] a substantial amount, in 1649.[14] By 1653, Reynier Bolnes was bankrupt.[14] Thins derived income from annuities, interest income, and property rentals, including farmland.[17] She also lived off of the capital of her investments. Thins and her sister Cornelia Thins (d. 1661) received a sizeable inheritance from their brother Jan Willemsz Thins following his death in 1651.[4] Thins attained a comfortable standard of living of 15,000 or more guilders a year in the 1660s.[4]

Cornelia died in 1649.[18] In 1664, Thin's son Willem, a jobless bachelor, was locked up in an institution after an argument with his mother, and for attacking Catharina, his pregnant sister, with a stick.[13][19][20] In 1665, Maria Thins was entrusted with her son's property. She wrote a will, which limited Willem's share to the legal minimum of one sixth of her estate. She mentioned that he had been calling her names since his youth.[13][19] Willem died in 1676.[21]

Thin's daughter, Catharina, came to know Johannes Vermeer and wished to marry him. Her mother disapproved of the marriage because he was not Catholic, and also likely because he was of a lower artisan class.[22] By 1652, Vermeer helped his mother run the family's inn and was an art dealer, taking over his deceased father's business.[6] Before they married, Thins stated that although she did not approve, she would not prevent Catharina and Vermeer from marrying.[6][23] Vermeer likely converted from Reformed Protestant to Catholicism by the time of their union.[24] Catharina and Vermeer married in Schipluy (present-day Schipluiden) on 20 April 1653.[25] By December 1660, the Vermeers lived in the large house of his wealthy mother-in-law Maria Thins, described as a "strong-willed" woman. It was unusual at the time for married men and women to settle into the houses of their parents.[26] Vermeer relied on Thin's residence and financial support to take care of his family.[27]

Vermeer painted in the artist's studio[28] and sold art from the house.[9] His works portray subjects with clothing and furnishings more luxurious than his own.[29] Biographer Anthony Bailey claims that since Vermeer used models from his household, it is likely that he made a painting of his wife. He asserts that Catharina is depicted in A Lady Writing a Letter due to her "fond expression" and "concentrated gaze of the unseen painter."[30]

Thins played an essential role in their life. She was a devotee of the Jesuit order in the nearby Catholic Church, and this seems to have influenced Johannes and Catharina.[31]

They had eleven children at the time of Vermeer's death,[32] four of their children died young between 1660 and 1673.[9][33] Most of their children were born at Thin's house.[28] Their third son was called Ignatius, after the founder of the Jesuit Order.[31] Catharina inherited the Ben Repas estate following her Aunt Cornelia's death in February 1661.[34]

Thins hired Vermeer to manage financial issues for her in 1667 and 1675. He collected monies owed her, and he handled her investments.[35] The Rampjaar (disaster year) following the outbreak of the Franco-Dutch War (1672–1674) was particularly hard on Vermeer's ability to make money as an artist and an art dealer. He had to take a loss on sales of works of art and was unable to sell his own works.[32] His mother-in-law was financially strained during this period due to the loss of rental income from farmland due to the war. In one instance, she rented out land near Schoonhoven that was flooded to prevent the French army from crossing the Dutch Water Line. The farmland was not arable for a time.[36][37] Thins reduced the money that she spent to support the Vermeers.[37] In 1675, Vermeer went on several business trips for his mother-in-law, first to Gouda, when her husband had died, and then to Amsterdam. There Vermeer borrowed money by fraudulently using her name.[36][37]

Vermeer died and was buried on 15 December 1675. Unable to pay their debts, Catharina blamed the financial fallout of the war for their losses and petitioned for bankruptcy in April 1676.[6][38] Ten of their eleven children were still underage when Vermeer died. Catharina continued to live at her mother's house with their children.[32] After Vermeer's death, Maria Thins received The Art of Painting for her financial support of Catharina's family.[39] Catharina paid off other debts with paintings or used them as surety until she paid off debts.[40]
