Michael, the name of the angel mentioned in the Bible, the guardian of the garden of Eden appointed by God, is also the only spirit with the title of Archangel. The name Michael means "similar to God". Michael mentioned only Michael and Gabriel in the Old Testament, but Michael was the most dazzling and famous Archangel in Christian culture.
According to the Bible, in the seven day war with Satan, Michael fought against God's opponents and finally defeated him. In Christian Paintings and sculptures, Michael often fights with the dragon with long blond hair and holding a Red Cross (or Red Cross sword), standing on the dragon or becoming friends with the dragon. The Dragon here is Satan.
