March 18 was the historical feast of the Archangel Gabriel, one of the three archangels mentioned by name in the Bible.
Gabriel is the Angel of Annunciation, who came to Mary, Joseph, et al telling them of that Mary was pregnant with the Son of God.
Gabriel is also the angel who came to Mohammed and gave him the Quran.
Other sources also say that Gabriel is the angel who gave Geomancy to Hermes Thrice Great as a means of divination.
Gabriel has done some miracles for me and I try to remember and honor Gabriel often.
I often feel as though Gabriel is overlooked and forgotten, as Michael or Raphael seem much more popular and loved,
And of course the Roman Catholic church did away with all the feasts of the angels, centering them around Michaelmas in September.
If you interested in Gabriel, you should pick a prayer and set a light to them and ask for their aid.
