Rebus of Bishop Oldham
A group of words or phrase written by figures or pictures of objects whose names resemble in sound the words or syllables of which they are composed. In heraldry a rebus is a device on a coat of arms conveying an allusion to the name of the person, as castles for Castleton, three cups for Butler. The accompanying cut show a rebus on a personal name (not very happy attempts, however), standing for the name Oldham (Owledom).
