A key into the language of America is a 1643 London vocabulary and ethnographic guide by Roger Williams, printed by Gregory Dexter, describing the language and customs of the Narragansett natives of New England for English settlers. The two pictures are small typographic ornaments: a banner lettered GAUDEO above a seated griffin-like bird, and a symmetrical strip of scrolling foliage with a central urn-like figure, both in black ink on a yellow ground, offering a designer compact emblem and border motifs with strong symmetry.
