Michaelmas
masc. proper name, name of an archangel, from L.L., from Gk. Mikhael, from Heb. Mikha-el, lit. "Who is like God?" Michaelmas is first attested 1123 (Sanct Micheles mæsse), the feast of St. Michael (Sept. 29, an English quarter-day), from Goose is the day's traditional fare since at least 15c.

From the Hebrew name מִיכָאֵל (Mika'el) which meant "who is like God?". This is the name of one of the seven archangels in Hebrew tradition and the only one identified as an archangel in the Bible. In the Book of Revelation in the New Testament he is portrayed as the leader of heaven's armies, and thus is considered the patron saint of soldiers. This was also the name of nine Byzantine emperors and a czar of Russia.

MICHAEL (Hebrew Sn,q, " Who is like God? ") , an Old Testament name, synonymous with Micaiah or Micah (Num. xiii. 13; I Chron. v.13 et passim). In the book of Daniel the name is given to one of the chief " princes " of the heavenly host, the guardian angel or " prince " of Israel (Dan. x. 13, 21; xii. I; cf. Enoch xx. 5 and possibly Mal. iii. I), and as such he naturally appears in Jewish theosophy as the greatest of all angels, the first of the four (or seven) who surround the throne of God, and the antagonist of Sammael, the enemy of God. He holds the secret of the mighty "word" by which God created heaven and earth (Enoch lxix. 14), and was " the angel who spoke to Moses in the Mount " (Acts vii. 38).

It was through Babylonian and
Persian influence that names were given to the angels, and according to Kohut (Jiid. Angel. p. 24) Michael is parallel to Vohumano, " Ahura's first masterpiece," one of the Zoroastrian Amesha-spentas or archangels, It is as guardian angel of Israel, or of the Church, the true Israel, that Michael appears in Jude 9 and Rev. xii. 7. This latter passage is of distinctly pre-Christian origin; it is not the Child that overthrows Satan, the figure of the Messiah is ousted by that of Michael. There is also here a relic of the primeval Babylonian myth of the struggle between the light god Marduk and the forces of chaotic darkness. In the Western Church the festival of St Michael and All Angels (Michaelmas) is celebrated on the 29th of September; it appears to have grown out of a local celebration of the dedication of a church of St Michael either at Mount Garganus in Apulia or at Rome, and was a great day by the beginning of the 9th century. The Greek Church dedicates the 8th of November to St Michael, St Gabriel and All Angels.
