THE UNIVERSE

Two Books:

Or A Compendium of Celestial Doctrine.

A small hand-drawn ink sketch depicts a standing figure, possibly a reader's mark or shelf mark.

Third edition.

The printer's mark of Joannes Maire is an oval woodcut emblem showing a man in simple clothing laboring in a field, digging with a spade. In the sky above him, rays of light emerge from clouds. A scroll within the emblem bears the motto "FAC ET SPERA" Do and Hope. The oval is surrounded by a decorative laurel wreath tied with a ribbon at the base.

From the workshop of JOANNES MAIRE.
