The History of the School Crest
They are particularly famous because the Drapers Company was, in 1439, the first corporate body in England to be granted a coat of arms.
In plain English this means:
The school crest that is most commonly used and with which most of us are familiar is this:
The Drapers’ Company’s patron is the Virgin Mary. It has been suggested that the arms represent that from Mary, through the Holy Spirit, comes the divine Son of God: thus the sunbeams represent the brilliance and light of the Virgin Mary, and the cloud which is a frequent symbol for the Holy Spirit. Mary was deemed to be an empress; the symbol for an emperor/empress is the triple crown, still in use by the Vatican City.
The triple repetition is dictated by the general principle of three charges to a shield apparent in medieval heraldry.
