Caroli Ruaei e Societate Jesu Carminum libri quatuor
Caroli Ruaei's Carminum libri quatuor is a Latin poetry collection by Jesuit Charles de La Rue, printed in Paris in 1688 for scholarly and religious readers. Its pictures are engraved emblem-style roundels, each with a Latin motto on a scroll around a small scene of a tree, bird, sun, or landscape, showing how a designer might frame text inside a circular medallion.
