The “cross clechy” was originally a variant form of the crosses formy and patonce: it was blazoned a crux florida patens in the Boke of St. Albans, 1485, and used in the arms of da Lisson, mid-15th Century [Triv 201]. Modern heraldry texts sometimes blazon it as a “cross urdy”; in Society blazonry, the latter term is reserved for the cross as an ordinary with a complex line of division.
Teleri Tawel bears: Sable, in chief three crosses clechy Or.
Antonio Giovanni Pecoraro bears: Per pale and per chevron argent and azure, three crosses clechy counterchanged.
