Antwerp Mannerism refers to the style of a group of largely anonymous painters active in the southern Netherlands, principally in Antwerp, in roughly the first three decades of the 16th century. The movement marks the tail end of Early Netherlandish painting and an early phase within Dutch and Flemish Renaissance painting. The style bore no relation to Italian Mannerism, which it mostly predates by a few years, but the name suggests that it was a reaction to the "classic" style of the earlier Flemish painters, just as the Italian Mannerists were reacting to, or trying to go beyond, the classicism of High Renaissance art.
The Antwerp Mannerists' style is certainly "mannered", and "characterized by an artificial elegance. Their paintings typically feature elongated figures posed in affected, twisting, postures, colorful ornate costumes, fluttering drapery, Italianate architecture decorated with grotesque ornament, and crowded groups of figures...". Joseph Koerner notes "a diffuse sense of outlandishness in Antwerp art, of an exoticism both of subject and means ... evoking a non-localized elsewhere".
