Hi Bob This is my take on the Crest
The Outer Circle consists of the College Motto CRVX MEA LVX or The Cross is my Light and Coll: Rosic: Scot: Occid: latin for West of Scotland College.
The Inner Circle contains the 12 signs of the Zodiac: Aries, Taurus, Gemini, Cancer, Leo,Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces
From the top Right St Mark is represented by the Lion on a Red Background, St John is represented by the Eagle on a Yellow Background, St Mathew is represented by the Angel or Man on a White Background and St Luke is represented by the Bull on a Black Background.
The cardinal points North, South, East and West are symbolic of the Angels Uriel, Michael,Raphael and Gabriel who preside over these quarters. The Symbols for Fire, Water, Air and Earth are displayed on the arms of the Cross.
