In ancient Roman religion, Virtus (Latin pronunciation: [ˈwɪrtuːs̠]) was the deity of bravery and military strength, the personification of the Roman virtue of virtus. The Greek equivalent deity was Arete. The deity was often associated with the Roman god Honos (personification of honour) and was often honoured together with him, such as in the Temple of Virtus and Honos at the Porta Capena in Rome. It was after the conquest of Syracuse in 205 B.C.E that the Virtus portion of the temple was added, and in such a way that one had to enter the temple of Virtus before Honos, symbolizing that honor cannot be obtained without military success.
Virtus also served as a deity to represent a continuous belief of virtue, after the Fall of Rome. Virtus is mentioned throughout Christian Medieval literature, especially throughout the Byzantine Empire and States of the Holy Roman Empire at the time. Virtue, as represented by Virtus, represented both character traits, and mythical power.
