Saints Michael, Raphael, and Gabriel & Artistic Symbolisms

Three Archangel Saints:
 Michael, Raphael (with Tobiah), and Gabriel
by Francesco Botticini (1470)
St. Michael - Is typically portrayed in armor to denote a victorious battle against Satan.
Then war broke out in heaven; Michael and his angels battled against the dragon.  The dragon and its angels fought back, but they did not prevail and there was no longer any place for them in heaven.  ~ Revelation 12:7-8

St. Raphael - Is depicted with Tobiah, a young man he traveled with to retrieve some money for his ailing father.  Botticini also included a fish that Tobiah had caught during the journey which helped to rid his future wife of some demons and later healed his father.  Botticini even added the fun detail of a dog joining St. Raphael and Tobiah on the journey (Tobit 6:2).

St. Gabriel - Is often illustrated holding a lily, a symbol of purity, especially in Annunciation scenes - when he went to visit Mary.  St. Gabriel's red wings in this particular painting might represent the Holy Spirit and how it was this archangel who let Mary know she would conceive Jesus miraculously through the Holy Spirit.

Saints Michael, Raphael, and Gabriel share September 29 as a Feast Day.
