In 1828 he sold a number of papyri to the Dutch government, which were lodged at the Leiden University Library, and labelled alphabetically from A to Z.
[4] Papyrus V contains a recipe for a mystical ink made of misy (oxidized pyrite ores, a mix of copper and iron sulfates), green vitriol, oak apple, gum, and of a substance composed of 7 perfumes and 7 flowers.
Traces of this nomenclature survive in botanical names, like in German "Löwenzahn" (dandelion: lion's tooth) and wolf's milk; also in dragon's blood, which probably still denotes the same resin as in ancient times.
The 7 perfumes are given as: styrax dedicated to Saturn, malabathrum to Jupiter, costus to Mars, frankincense to the Sun, nard to Venus, cassia to Hermes, myrrh to the Moon.
For example, Kurt Sprengel's edition of De materia medica writes that mercury is stored in glass, leaden, tin and silver vessels.
While it is true that glass is unaffected by mercury, all the metals named are attacked, and Zosimus takes special care in pointing that out.
