Fredericus, by Eligio Cazzato, is a board game for 2-4 falconers at the court of Kaiser Frederik II in Castel del Monte. The box includes 105 cards, an illustrated game board, and a falcon, hawk, and betting coin for each player. The goal of the game is to catch as many mythological beasts as possible. After each capture, the catches of the other players can be bet on and the Kaiser can award prizes to the players.
