Michaelis Majeri Viatorivm, hoc est, De montibvs planetarvm septem seu metallorum : tractatvs tam utilis, quàm perspicuus, quo, ut indice mercuriali in trivijs, vel Ariadnêo filo in labyrintho, seu cynosurâ in oceano chymicorum errorum immenso, quilibet rationalis, veritatis amans, ad illum, qui in montibus sese abdidit De Rubea-petra Alexicacum, omnibus medicis desideratum, investigandum, uti poterit
Michael Maier's Viatorium, a Latin alchemical treatise on the seven planetary mountains and their metals, issued at Rouen in 1651 by Jean Berthelin for learned physicians and adepts. Small copper engravings mix planetary gods with their attributes and beasts against emblematic narrative scenes: a sailing ship with flying dragons, a tent murder at a banquet table, a butcher's stall under trees.
