Michaelis Maieri viatorium, hoc est, de montibus planetarum septem, seu metallorum

MICHAEL MAIER'S
VIATORIUM,
THAT IS,
ON THE MOUNTAINS OF THE SEVEN
PLANETS, or of the Metals;

A TREATISE as useful as it is clear,
by which, as with a Mercurial Mercury-led index at a crossroads, or an Ariadnean guiding thread in a Labyrinth, or a Cynosure a guiding star in the immense ocean of Chemical errors,
any rational person, a lover of truth, will be able to use it to investigate that Alexicacum remedy hidden in the mountains, from the Red Stone a reference to the Philosopher's Stone, desired by all physicians.

A circular emblem features a central Mercury symbol surrounded by the symbols of the seven classical planets (Sun, Moon, Mars, Venus, Jupiter, Saturn, Mercury) within a decorative border.
