Over the years, the Castle Museum's collection has also included some outstanding reverse glass miniatures due to its focus on reverse glass painting: The rosary made of ibex horn with glass inserts, made around 1600, was made in Salzburg. The reverse glass miniatures used refer to Lombardy and were made in the first half of the 18th century. The reverse glass miniature in gold setting shows a depiction of St. Mary Magdalene on the front and a depiction of St. James (Sant Jago Matamoris) fighting against the infidels on horseback on the back. The painting probably comes from Spain or Portugal in the first half of the 18th century. The third object is a so-called plague blessing. The amulet made of ibex horn contains a high oval rock crystal, which was painted with a male bust portrait to the right, with a crown and halo. The segments with relic particles arranged on the back are typical of the plague blessing. Its setting consists of an openwork ornamental wreath with eight oval rock crystals, which also contain relic particles. The plague blessing was carved from the cross-section of an ibex horn. Like the saint's portrait, the ibex horn was said to have apotropaic (i.e., evil-repelling) powers; it was considered to be detoxifying and wound-healing.
