Holbein carpet are a type of Ottoman carpets taking their name from Hans Holbein the Younger, due to their depiction in European Renaissance paintings. Actually, these in fact are seen in paintings from many decades earlier than Holbein. The art historian Kurt Erdmann has sub-divided the "Holbein" design into four types (of which Holbein actually only painted two); they are among the commonest designs of Anatolian carpet seen in Western Renaissance paintings. Their production started by the mid-15th century, and continued to be produced for nearly two centuries. All are purely geometric and use a variety of arrangements of lozenges, crosses and octagonal motifs within the main field. The sub-divisions are between:
Type I: Small-pattern Holbein. This type is defined by an infinite repeat of small patterns, with alternating rows of octagons and staggered rows of diamonds, as seen in Holbein the Younger's Portrait of Georg Gisze (1532), or the Somerset House Conference (1608).
Type II: now more often called Lotto carpets.
Type III: Large-pattern Holbein. The motifs in the field inside the border consist of one or two large squares filled with octagons, placed regularly, and separated from each other and from the borders by narrow stripes. There are no secondary "gul" motifs. The carpet in Holbein's The Ambassadors is of this type.
Type IV: Large-pattern Holbein. Large, square, star-filled compartments are combined with secondary, smaller squares containing octagons or other "gul" motifs. In contrast to the other types, which only contain patterns of equal scale, the type IV Holbein shows subordinate ornaments of unequal scale.
Holbein frequently used carpets in portraits, on tables for most sitters, but on the floor for Henry VIII.
