Peter Ernst von Mansfeld
Hildebrandt, Johann Lukas von
Hildebrandt took over responsibility (1703) for the design of the Church of St Peter, Vienna (begun 1702 by Gabriele Montani), planned as a longitudinal ellipse crowned by a cupola, flanked by two rectangular compartments and an apsidal choir. The tall entrance-front is flanked by twin towers set at angles, giving great drama to the composition. Franz Jänggl (1650–1734) was involved in the construction of the building. A variant of the plan of the Peterskirche was used for the Seminarkirche (Seminary Church), Linz (1717–25). From 1698 Hildebrandt worked (possibly with a contribution from K. I. Dientzenhofer) on the beautiful Piaristenkirche (Piarist Church) of Maria Treu, Vienna (built by Jänggl, 1716–31), which has a similar plan to that of the Gabel church. Completed (1751–3) by the Piarist Mathias Gerl (1712–65), the church is by far the lightest and most joyous in a city where the Baroque tends to be sombre.
Hildebrandt's greatest work is arguably the Belvedere, Vienna (1714–24), the dream-palace of Prince Eugen, with almost oriental roofs and frothy façades with shaped pediments and corner towers. There are, in fact, two buildings—the Upper and Lower (1714–16) Belvedere—linked by a series of terraced gardens, with statuary and planting. The Upper Palace contains the most celebrated of Hildebrandt's staircases where massive, struggling atlantes carry heavy vaulting. He also designed the staircase with urns and putti at Schloss Mirabell, Salzburg (1721–7). Other fine staircases can be found at the Palais Daun-Kinsky, Vienna (1713–16), and Schloss Weissenstein, Pommersfelden (1711–15)—where he also designed the central pavilion. From 1720 to 1723 and again from 1729 to 1744 he collaborated with Neumann on the Residenz of the Prince-Bishop at Würzburg: his hand is evident in the shaped pediments of the central pavilion as well as in the Kaisersaal ( Emperor's Hall) and Chapel. He was involved in the rebuilding of the Stift (Monastery) of Göttweig from 1719: his plans were ambitious but never fully realized, although the building containing the Kaiserstiege (Emperor's Stair) of 1738 is as fine as anything he conceived.

Mansfeld, Peter Ernst von
Peter Ernst von Mansfeld (pā´tər ĕrnst fən mäns´fĕlt), 1580?–1626, military commander in the Thirty Years War. Illegitimate son of a governor for the Hapsburgs in Luxembourg, he rendered distinguished service in the imperial forces in the Netherlands and was legitimized; by 1607 he was styling himself count. At the beginning of the Thirty Years War, Mansfeld and his army were loaned by his employer, the duke of Savoy, to Frederick the Winter King, in Bohemia. Frederick's funds ran low, however, and shortly before the battle of the White Mt., Mansfeld refused further service. A promise of Dutch funds later induced him to defend Frederick's possessions in the Palatinate. He was at first successful and proved himself skillful in command. He won an engagement with Tilly in 1622, but he was unable to oust the imperial forces, and his unruly men ravaged and terrorized the country. Frederick dismissed him. He became (1623) a mercenary leader for Holland and in 1625, with a subsidy from England, recruited a force to fight on the Protestant side. He was severely defeated (1626) by Wallenstein near Dessau. Mansfeld attempted then to cooperate with Gabriel Bethlen but without success.
