The symbolism is most likely to represent The Assumption of the Virgin; in the margins of the Letters Patent of the Grant, Mary is being crowned by angels. It has been suggested that the arms demonstrate 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. Another suggestion is that the crowned clouds are mistaken renderings of pyx-canopies, that is veils (as would be sold by drapers) hanging from pyxes.
