"Lionel was a little heraldic lion, whereas Leo was a big live beast."
Heraldry is concerned with the designing, describing and recording of coats of arms and heraldic badges.
Originally, the coat of arms was displayed as a means of identification on the medieval battlefield, but later become a sort of identificatory flag or logo for high status families. Institutions, such as universities, may also have coats of arms.
Coats of arms make use of visual symbols with particular meanings; the heraldic lion symbolises courage and strength.
