Northern Mannerism in the context of "Hercules"

Plaster is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements. In English, "plaster" usually means a material used for the interiors of buildings, while "render" commonly refers to external applications. The term stucco refers to plasterwork that is worked in some way to produce relief decoration, rather than flat surfaces.

The most common types of plaster mainly contain either gypsum, lime, or cement, but all work in a similar way. The plaster is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface. The reaction with water liberates heat through crystallization and the hydrated plaster then hardens.

Mannerism is a style in European art that emerged in the later years of the Italian High Renaissance around 1520, spreading by about 1530 and lasting until about the end of the 16th century in Italy, when the Baroque style largely replaced it. Northern Mannerism continued into the early 17th century.

Mannerism encompasses a variety of approaches influenced by, and reacting to, the harmonious ideals associated with artists such as Leonardo da Vinci, Raphael, Vasari, and early Michelangelo. Where High Renaissance art emphasizes proportion, balance, and ideal beauty, Mannerism exaggerates such qualities, often resulting in compositions that are asymmetrical or unnaturally elegant. Notable for its artificial (as opposed to naturalistic) qualities, this artistic style privileges compositional tension and instability rather than the balance and clarity of earlier Renaissance painting. Mannerism in literature and music is notable for its highly florid style and intellectual sophistication.

Rudolf II (18 July 1552 – 20 January 1612) was Holy Roman Emperor (1576–1612), King of Hungary and Croatia (as Rudolf I, 1572–1608), King of Bohemia (1575–1608/1611) and Archduke of Austria (1576–1608). He was a member of the House of Habsburg.

Rudolf's legacy has traditionally been viewed in three ways: an ineffectual ruler whose mistakes led directly to the Thirty Years' War; a great and influential patron of Northern Mannerist art; and an intellectual devotee of occult arts and learning which helped seed what would be called the Scientific Revolution. Determined to unify Christendom, he initiated the Long Turkish War (1593–1606) with the Ottoman Empire. Exhausted by war, his citizens in Hungary revolted in the Bocskai Uprising, which led to more authority being given to his brother Matthias. Under his reign, there was a policy of toleration towards Judaism.

Hendrick Goltzius (German: [ˈhɛndʁɪk ˈɡɔltsi̯ʊs], Dutch: [ˈɦɛndrɪk ˈxɔltsijʏs]; born Goltz; January or February 1558 – 1 January 1617) was a German-born Dutch printmaker, draftsman, and painter. He was the leading Dutch engraver of the early Baroque period, or Northern Mannerism, lauded for his sophisticated technique, technical mastership and "exuberance" of his compositions. According to A. Hyatt Mayor, Goltzius "was the last professional engraver who drew with the authority of a good painter and the last who invented many pictures for others to copy". In the middle of his life he also began to produce paintings.

Bartholomeus Spranger or Bartholomaeus Spranger (21 March 1546 – 27 June 1611) was a Flemish painter, draughtsman, sculptor, and designer of prints. Working in Prague as a court artist for the Holy Roman emperor Rudolf II, he responded to his patron's aesthetic preferences by developing a version of the artistic style referred to as Northern Mannerism. This style stressed sensuality, which was expressed in smoothly modeled, elongated figures arranged in elegant poses, often including a nude woman seen from behind. Spranger's unique style combining elements of Netherlandish painting and Italian influences, in particular the Roman Mannerists, had an important influence on other artists in Prague and elsewhere, in particular the Dutch Republic, as his paintings were disseminated widely through prints as well as by artists who had worked with him such as Karel van Mander.
