Thesaurus principum hac ætate in Europa viuentium : quo progenitores eorum, tàm paterni quàm materni, simul ac fratres & sorores, indè ab origine reconduntur, vsque ad annum à Christo nato 1590. : Libellus historiarum studiosis non minus vtilis, quàm cognitu necessarius,
Thesaurus principum is a 1590 genealogical reference printed in Cologne by Godefridus Kempensis, compiled by Michael Eytzinger for students of history who needed the family trees of living European rulers. The two pictures are a heraldic coat of arms with a banner reading Gauden, and a page of tabulated royal pedigree lines with numbered entries and a bordered column; a designer might borrow the crest's scrolled acanthus framing or the ruled, numbered genealogy chart as structural devices.
