Theatrum Pictorium
Theatrum Pictorium, or Theatre of Painting, is a short-hand name of a book published in the 1660s by David Teniers the Younger for his employer, the Archduke Leopold Wilhelm of Austria. It was a catalog of 243 Italian paintings in the Archduke's collection of over 1300 paintings, with engravings of the paintings taken from small models that Teniers had personally prepared. A second edition with page numbers was published in 1673. During the years 1646-1656 Leopold Wilhelm was governor of the Netherlands and formed one of the greatest art collections of his age. Teniers effectively  became its curator after the death of his predecessor Jan van den Hoecke in 1651. Leopold Wilhelm's collection came to hold works by Hans Holbein the Elder, Pieter Bruegel the Elder, Jan van Eyck, Raphael, Giorgione, Paolo Veronese and more than 15 works by Titian. Teniers made a list of the painters in the collection as part of the forward to his 1673 catalog: This list is an important document that reflects the contemporary taste in paintings in Brussels at that time. Of all the painters, the names Magdalena Woutiers and Madonna Fitta de Milano are the only women  whose work is documented as being in the Archduke's collection. No matter how illustrious the name however, only works by the better known Italian painters were chosen to be engraved for illustrations. At the end of his governorship, the Archduke and his collection moved to the Stallburg. This archducal collection now forms the heart of Vienna's Kunsthistorisches Museum. Before moving to Vienna in 1659, Archduke Leopold Wilhelm formed his art collection in Brussels, where David Teniers the Younger painted views of the most prized possessions of his Brussels gallery. He painted several of these in various compositions which  are now spread among various collections: Teniers employed a team of 12 engravers for reproducing the 243 paintings in the Theatrum. He produced small copies in oil of each of the chosen paintings, issuing these as models to his engravers and 120 of which were auctioned by the estate of John Spencer-Churchill, 7th Duke of Marlborough in 1886. Teniers’ painted copies measuring approximately 17 x 25 cm are now spread among various collections. The Courtauld Institute of Art Gallery holds 14 of these works, the largest group in any public collection. Of the 12 engravers, the five who contributed  most were Jan van Troyen with 56, Lucas Vorsterman the Younger with 52, Pieter van Lisebetten 40, Theodoor van Kessel 27, and Coryn or Quirin Boel 25. Johannes Popels contributed five engravings. Surviving works. The works listed in the book that survive are generally in the Kunsthistorisches Museum, while the modelli or small models for the engravings have been lost or are in other collections. The engravings and the modelli were inscribed with the dimensions of the original paintings, though their characteristics were often adjusted to take advantage of the maximum illustration possibilities of the album page size. The dimensions  were in the form "4 alta 3 lata", which means 4 palm-widths high and 3 palm-widths wide, such as the case with the engraving after Bassano's "Boy with a Flute":
