cites the Hellenistic lapidary of Damigeron as the ancient source from which his work was
derived. Damigeron is regarded as the first lapidary author to explicitly outline the impact of
astrological bodies upon stones and it is in Marbode’s text that the firm link between celestial
bodies and gemstones is introduced to the medieval Christian world.11 Subsequent lapidaries,
such as the work of Marsilio Ficino, follow the lead of Marbode: from the eleventh century
onward gemstones are largely tied to the stars in the catalog of their properties and
corresponding celestial bodies clearly inform their function.12 Furthermore, in this treatise
Marbode asserts that gemstones have a greater potency than that of any other natural substance:
they are granted power directly from God and are considered more potent than even the most
precious and marvelous herbs.13 Lapidaries, produced both in Latin and vernacular languages,
propagated this knowledge as well as belief in the power of gemstones throughout Europe. More
significantly, these texts preserved and communicated the belief in mineralogical amulets as
particularly valuable objects of protective power and offered guidance for their usage in
medieval scholarship.14 Inventories and literature referring to the properties of precious stones
and amulets further reflects the significance of lapidaries; the presence and influence of this
knowledge outside of a purely theoretical setting indicates that they were a part of a shared
cultural understanding of the natural world.15 Natural, brilliant substances were clearly

Modern Magic, 2016): XXXVI. Young makes note that Ficino’s work emphasized the power of astrological bodies
over stones and advised engraving the stone to amplify the object’s power. This, as Young states, was criticized by
his peers as “designed to attract demonic attention.”

references the Book of the Stones and states, “God himself, Marbode asserts, has endowed stones with singular
power. While herbs contain great strength, that of jewels is far greater.”

states that lapidaries were “responsible for passing onto the medieval world the classical belief in amulets, and, most
importantly, on magical jewels.

the magical virtues of gems, and the evidence of literature and the inventories of the period prove that this belief was
