Argonautica Gustaviana; das ist: Nothwendige Nachricht von der newen Seefahrt vnd Kauffhandlung; : so von weilandt allerdurchleuchtigsten, grossmächtigsten vnd siegreichesten Fürst vnnd Herrn, Herrn Gustavo Adolpho Magno .
Argonautica Gustaviana is a 1633 German-language account by Willem Usselincx of a Swedish overseas trading venture, printed at Frankfurt am Main by Caspar Rödteln for readers interested in the Swedish crown's commerce. The single picture is an engraved heraldic achievement with a crest of a fox-like animal above an ornate mantling, a shield bearing a chevron and three figures, and the motto GAUDEO beneath. A designer could draw on its symmetrical scrollwork, mantling and shield layout as a model for crest or emblem design.
