Since the Archangel Michael was made the guardian of the Hebrew nation, he was naturally an important actor in many scenes connected with their history. It was he who succored Hagar in the wilderness (Genesis xxi., 17), who appeared to restrain Abraham from the sacrifice of Isaac (Genesis xxii., 11). He brought the plagues on Egypt and led the Israelites on their journey. The Jews and early Christians believed that God spake through the mouth of Michael in the Burning Bush, and by him sent the law to Moses on Mount Sinai. When Satan would have entered the body of Moses, in order to personate the prophet and deceive the Jews, it was Michael who contended with the Evil One, and buried the body in an unknown place, as is distinctly stated by Jude. Signorelli chose this as the subject of one of his frescoes in the Sistine Chapel, and I have seen no other representation of it, although I believe that a few others exist. It was Michael who put blessings instead of curses into Balaam’s mouth (Numbers xxii., 35), who was with Joshua in the plain of Jericho (Joshua v., 13), who appeared to Gideon (Judges vi., 2), and delivered the three faithful Jews from the fiery furnace (Daniel iii., 25). This last subject is one of the earliest in Christian art, and was a symbol of the redemption of man by Jesus Christ. There are still other like offices which St. Michael filled as the protector of the Jews, while several important works are attributed to him in the Apochrypha and in the Legends of the Church. For example, in the apochryphal story of Bel and the Dragon, it is related that when King Cyrus had thrown the prophet Daniel into the lions’ den, and he had been six days without food, the angel of the Lord appeared to the prophet Habakkuk in Jewry, when he had prepared a mess of potage for the reapers in his field, and the angel commanded Habakkuk to carry the potage to Babylon and give it to Daniel. “Then Habakkuk said, ‘Lord, I never saw Babylon; neither do I know where the den is.’ Then the angel of the Lord took Habakkuk by the hair of his head, and set him in Babylon over the lions’ den; and Habakkuk cried, saying, ‘O Daniel, Daniel, take the dinner which God hath sent thee,’--and the angel again set Habakkuk in his own place.” At one period this subject was represented on sarcophagi; but I have only seen it in prints after the Flemish artist, Hemshirk. In the legends of St. Michael we read that in the sixth century, when the plague was raging in Rome, and processions threaded the streets chanting the service since known as the Great Litanies, the Archangel Michael appeared, hovering over the city. He alighted on the summit of the Mausoleum of Hadrian and sheathed his sword, from which blood was dripping. From that hour the plague was stayed, and from that day the Mausoleum, which is surmounted by a statue of the Archangel, has been called the Castle of Sant’ Angelo.
