The Austrian Mint have issued (22nd February) a new coin that inaugurates a four-coin series dedicated to “Heavenly Messengers.” Through the ages, believers have looked to angels for protection; the divine beings are worshiped by Christians, Jews, and Muslims alike. These benevolent but invisible spirits have been widely depicted throughout art history, and one of the more famous is the Archangel Michael. Known in many Christian denominations as “Saint Michael the Archangel” or simply as “Saint Michael,” he is mentioned in both the Hebrew scriptures (or Old Testament) and the New Testament’s Book of Revelation. Michael is also mentioned in the Quran as Mikhail, and attributed as being one of the three angels who visited Abraham. As the leader of the holy legion, Michael has a particularly devoted following. He became the patron saint of the Holy Roman Empire after the victorious battle of Lechfeld in 955. In late medieval Christianity, Michael, together with Saint George, became the patron saint of chivalry—the code of conduct associated with the medieval institution of knighthood. In the modern world, Michael is considered the patron saint of police officers, paramedics, firefighters, and the military, predominantly due to his folklore as a warrior. His primary Western liturgical feast day is celebrated on the 29th September and referred to by many as “Michaelmas.” In the Eastern liturgical calendar, it is on the 8th November when all archangels are honoured.
