# Flavio Gioja

> Flavio Gioia or Gioja, also known as Ioannes Gira Amalphensis is reputed to have been an Italian mariner, inventor, and supposedly a marine pilot. He has traditionally been credited with developing the sailor's compass, but this has been debated. However, he is credited with perfecting it by suspending its needle over a wind rose design with north designed by a fleur-de-lys, and enclosing it in a box with a glass cover. He was also said to have introduced such design, which pointed North, to defend against Charles of Anjou, the French king of Naples.
