Minotaur's Horn

The Minotaur's horn was a spoil of war claimed by Percy Jackson when he defeated the Minotaur.

The Lightning Thief
In The Lightning Thief, Percy snapped off the Minotaur horn, and used it as a weapon against the Minotaur. The horn was only mentioned a few times after the first book. It first started out as Percy's only possession when he came to camp but, at the end of the book it became his prized trophy that he hung up on his cabin wall. It was again mentioned in The Sea of Monsters when Percy first entered his cabin and late on when Percy hung up his shield next to it on the cabin wall. Finally, though it was not seen, it was mentioned when Percy confronted the Minotaur a second time in The Last Olympian.
