Pieter Coecke van Aelst or Pieter Coecke van Aelst the Elder (Aalst, 14 August 1502 – Brussels, 6 December 1550) was a Flemish painter, sculptor, architect, author and designer of woodcuts, goldsmith's work, stained glass and tapestries. His principal subjects were Christian religious themes. He worked in Antwerp and Brussels and was appointed court painter to Charles V, Holy Roman Emperor. Coecke van Aelst was a polyglot. He published translations into Flemish (Dutch), French and German of Ancient Roman and modern Italian architectural treatises. These publications played a pivotal role in the dissemination of Renaissance ideas in Northern Europe. They contributed to the transition in Northern Europe from the late Gothic style then prevalent towards a modern 'antique-oriented' architecture. Life Pieter Coecke van Aelst was the son of the Deputy Mayor of Aalst. The early Flemish biographer Karel van Mander wrote in his Schilder-boeck published in 1604 that Coecke van Aelst studied under Bernard van Orley, a leading Renaissance painter based in Brussels. There are no documents that prove this apprenticeship but there are strong stylistic similarities between the styles of the two artists. According to Karel van Mander, Pieter Coecke van Aelst later studied in Italy where in Rome he made drawings after Classical sculpture and architecture. Although there is no firm evidence that Coecke van Aelst travelled to Italy, stylistic evidence supports the notion that he travelled to Italy. The Italian influence could, however, also be attributed to the fact that Raphael’s tapestry cartoons were available in Brussels, where they were used for the manufacture of tapestries around 1516. However, as Coecke van Aelst clearly was familiar with Raphael's fresco of the Triumph of Galatea located in the Villa Farnesina in Rome, it seems likely he did in fact travel to Italy. Pieter Coecke van Aelst married twice. He married his first wife Anna van Dornicke in 1525 shortly after his move to Antwerp. Anna was the daughter of Jan Mertens van Dornicke, one of the most successful painters working in Antwerp. His father in law was possibly his teacher. Coecke van Aelst took over his father-in-law's workshop after the latter's death in 1527. There were two children from this first marriage, Michiel and Pieter II. The latter was a painter. Printer Maarten Peeters and his wife were the legal guardians of Michiel and Pieter. After the death of his first wife before 1529, Coecke van Aelst had
