PT Journal AU Ulicny, P TI Vysehrad in the period of Charles IV and Wenceslas IV. Unknown appearance of the royal castle in the early 17th century iconography SO Staleta Praha PY 2017 BP 120 EP 143 VL 33 IS 1 DI 10.56112/sp.2017.1.05 WP https://staletapraha.cz/en/artkey/pha-201701-0005.php DE Prague - Vysehrad Castle - palace - fortification - rotunda of St Martin - Charles IV - Wenceslas IV - Giovanni Pieroni - Aegidius Sadeler - Roelandt Savery - Paulus van Vianen SN 02316056 AB The University Library in Bologna possesses a plan dated circa 1626, by the Florentine architect and military engineer Giovanni Pieroni, concerning proposed fortification with a contemporary survey of Vysehrad castle, drawn in particular detail in the area of the ruined former royal acropolis prior to its Baroque redevelopment to a fort, providing a valuable glimpse of the earlier constructions. Additionally the plan depicts elements not revealed from the archaeological excavations, comprehensively published in 2004-2015. Also prospects by the Dutch draftsmen, Roelandt Savery and Paulus van Vianen, who worked in Prague at the court of Rudolph II, are equally valuable for the topography of Vysehrad. These documents help to interpret other known iconographic sources, mainly the two Sadeler's prospects from 1606, and depict the royal acropolis in greater detail. They also bring new knowledge of its layout in the period of Charles IV and Wenceslas IV, especially regarding the questions about its gates and palaces. ER
