"Aertgen Claesz. van Leyden (Leiden, c. 1498 – Leiden, c. 1564), also known as Allaert or Aert van Leyden or Aert Claesz. van Leyden, was a 16th-Century Dutch painter, draughtsman and designer of stained glass. Works by this artist can be found at the Rijksmuseum in Amsterdam, Stedelijk Museum De Lakenhal in Leiden, the Metropolitan Museum of Art in New York and Museo Thyssen-Bornemisza in Madrid.
According to the biographer Karel van Mander (1604), Van Leyden was a son of a Leiden fuller. In 1516, he became an apprentice to the Leiden painter Cornelis Engebrechtsz. Some sources incorrectly name Aertgen van Leyden as a brother of Lucas van Leyden; in fact, Lucas van Leyden was the son of a painter, Hugo Jacobsz." - (en.wikipedia.org 13.12.2020)
