The blazon

per fesse, gu. and ar. a pale, counterchanged, and three plates on the first. [Confirmed, hy Sir William Segar, Garter, 7th May, 1628, to Nathaniel Lavender, of London, Esq. Herald's Office, Herts and Middlesex, C. 28.]

A blazon is the description of a coat of arms in the technical language of heraldry. The drawing comes from that text, and from nothing else.
