Pieter, Peeter, or Peter Danckerts de Rij, Dankers de Ry, or Peteris Dankersas (1605, Amsterdam - 9 August 1661, Rudnik) was a Dutch Golden Age painter. He was the son of Cornelis Danckerts de Ry, member of a large family of printers, painters and engravers. Adam Kazanowski - by Peeter Danckers de Rij. Example of Dankerts-Sandrart collaboration in print of PC Hooft. This 1642 engraving was painted by Sandrart, etched by Reinier van Persijn, and printed by Danckerts. The poem in Latin at the bottom was written by Caspar Barlaeus.Cornelis is mentioned in Houbraken's Schouburg as being one of the many teachers of Joachim von Sandrart in 1640-41, though considering Sandrart's age and experience (he had just returned to the North from his Grand Tour to Italy), this was more of a collaboration. Since Filippo Baldinucci later wrote a biograhical sketch on Pietro Danckerse de Ry in his list of artists called the Notizie, it is possible that Danckerts visited Italy at some time. In any case Sandrart engraved some of Peter's paintings after this period. Peter was active until 1640 in Amsterdam, and then he moved to Warsaw, Danzig, and Vilnius in the Polish-Lithuanian Commonwealth. He was active in Poland as the court painter and architect of the Polish King Władysław IV Vasa. According to Houbraken a poem was written in his honor that applauds his work in Poland. He died as the result of a highway robbery in the Redininkai Forest near Vilnius, Lithuania.
