In Prague’s St. Vitus Cathedral stands a bronze tomb of exceptional artistry depicting Ludmilla Berka (†1558) with her two sons. Since Aloys Hirt’s mention in 1830, it has been attributed to the Nuremberg Vischer workshop or an unidentified German master. Recent findings reveal the Vischer workshop ended sepulchral production by 1544, and the monument diverges stylistically from its oeuvre. Commissioned by Ludmilla’s husband Franz von Thurn—Obersthofmeister at the court of Archduke Ferdinand of Tyrol—, it may plausibly be the work of an as yet unidentified Flemish sculptor from the circle of Mechelen-born Alexander Colin, active at the Habsburg court in Innsbruck from 1563. Casting likely occurred in the Löffler workshop in Innsbruck. The monument’s opulence and technical sophistication fully reflects Thurn’s high social standing and Ludmilla’s role as governess to the children of Emperor Ferdinand I.
