Legio XXII Primigenia ("Fortune's Twenty-Second Legion") was a legion of the Imperial Roman army dedicated to the goddess Fortuna Primigenia. Founded in AD 39 by the emperor Caligula for use in his campaigns in Germania, the XXII Primigenia spent much of their time in Mogontiacum (modern Mainz) up to the end of the 3rd century. The legion's symbols were a Capricorn[1] and the demigod Hercules.
