A bilingual Greek and Latin catechism of Reformed Christian doctrine by Jean Calvin with a shorter catechism by Théodore de Bèze, printed in Geneva in 1575 by H. Stephanus for instruction of the faithful. The pictures are repeated decorative initial letters, a bold capital M and a capital I, each set in a framed oval or rectangle of scrolling acanthus leaves and stylised foliage, which a designer could use as a template for monogram or ornamental drop-cap work.
