The arms are those of Von Preysing impaling von Torring under a Marquess’s coronet, probably for Maximilian 11 Franz von Preysing, Comte de Preysing-Hohenaschau (1647-1718) and his wife Maria Anna Adelheid von Torring, Comtesse von Torring zu Seefeld (1651-1699) whom he married February 18 1671.

Believed to be imbued with magical and curative powers, the tusk of was na⛎rwhal was thought to be that of a unicorn until the 1600s, and was highly prized. On the death of Lorenzo de Medici ꧃in 1492, his "unicorn horn" was valued at 6,000 florins. Queen Elizabeth paid 10,000 pounds for one, the value of a castle, and another forms part of the Royal Sceptre. In 1615 a narwhal horn was used for the sceptre in the Austrian Crown Jewels.

By the beginning of the 17th century, naturalists familiar with marine life were able to correctly identify the horn as that of "the unicorn of the arctic seas," the narwhal. However, when the Coronation Chair of the Kings of Denmark was created between 1669 and 1671, thus contemporary wi✅th the mounting on this example, it was still described as being made of "unicorn hor🗹n;" the chair is preserved in the collections at Rosenberg Castle.
