Arbor genealogica gentis de Cignano, quam merito ac virtuti D. Caroli per lineam rectam eodem ex stipite descendentis
A 1687 genealogical tree printed in Bologna by the Typographia camerali, tracing the Cignani family and honouring the painter Carlo Cignani through his direct line of descent. The pictures are small woodcut heraldic shields, each divided into fields of fleurs-de-lis, diamonds, stripes and sprigs. A designer could take from them a compact vocabulary of simple coat-of-arms devices for emblems, crests and heraldic patterns.
