starting signal of the research project

On 28 April 2016, representatives of the Federal Monuments Office came for a meeting to the Ferdinandeum in order to discuss the current state of the altar of Tyrol Castle. Dipl. Rest. (univ.) Laura Resenberg, Director of the Department of the restoration of paintings, sculptures and pieces of applied arts in the Tyrolean State Museums, informed about targets and measures of the intended art-technological investigations, which will proceed in three stages:

Phase 1: inventory of the wooden construction of the altar by imaging methods

  • x-ray images, if possible without causing damages: determination of wood types
  • drawing to scale and creation of a 3D-model
  • RTI images

Phase 2: examination of the altar surface

  • localization of animal skin and textile patches glued to the wooden surface and to the corner joints, position finding of wood defects
  • high-resolution infrared and UV images serving to localize preliminary drawings and retouches
  • stereo-microscopic examination of primer, paint layers, gold plating, silver plating and engravings
  • non-destructive material investigation by means of an x-ray fluorescence analysis

Phase 3: Creation of a concept to preserve/restore the altar based on the research results and its implementation

On 18 May 2016, the Federal Monument Office granted its permission to take x-ray pictures of the altar of Tyrol Castle. The Premonstratensian canon monastery of Wilten, the owner of this major work of art, had already given their consent previously. This represents the starting signal of the research project initiated by the Tyrolean State Museums.
