https://en.wikipedia.org/wiki/Tycho_BraheTycho's nose
An artificial nose of the kind Tycho wore. This particular example did not belong to Tycho.
In 1566, Tycho left to study at the University of Rostock. Here, he studied with professors of medicine at the university's famous medical school and became interested in medical alchemy and botanical medicine.[12] On 29 December 1566 at the age of 20, Tycho lost part of his nose in a sword duel with a fellow Danish nobleman, his third cousin Manderup Parsberg. The two had drunkenly quarreled over who was the superior mathematician at an engagement party at the home of Professor Lucas Bachmeister on 10 December.[13] Coming nearly to quarrel again with his cousin on 29 December, they ended up resolving their feud with a duel in the dark. Though the two were later reconciled, the duel resulted in Tycho losing the bridge of his nose and gaining a broad scar across his forehead. He received the best possible care at the university and wore a prosthetic nose for the rest of his life. It was kept in place with paste or glue and said to be made of silver and gold.[14] In November 2012, Danish and Czech researchers reported that the prosthetic was actually made of brass after chemically analyzing a small bone sample from the nose from the body exhumed in 2010.[15] The prosthetics made of gold and silver were mostly worn for special occasions, rather than everyday wear.
