Lapidary
A text describing precious and semiprecious stones, often including their supposed medicinal, protective, or magical powers.
Theophrastus: An ancient Greek philosopher whose surviving treatise On Stones describes minerals and their properties. His treatise is the earliest surviving systematic account of stones and a source for later lapidaries.
Gemstone: A mineral, rock, or organic material valued for beauty, rarity, or durability and used as an ornament. Gemstones are the principal objects described in lapidaries.
Medieval medicine: Medical practice in medieval societies, drawing on classical learning, religious traditions, and local knowledge. Descriptions of stones' curative effects belonged to the period's medical literature.
Doctrine of signatures: The belief that an object's appearance reveals its intended medicinal use. Lapidary claims helped sustain this way of linking visible form to hidden virtue.
Pliny the Elder: A Roman author whose Natural History compiled knowledge about the natural world, including gems and minerals. His descriptions helped transmit ancient claims about stones into later reference writing.
Mineralogy: The scientific study of minerals, including their composition, structure, properties, and formation. It supplies modern ways to identify and classify many stones discussed in lapidaries.
Gemmology: The study of natural and synthetic gemstones, including their identification, grading, and origins. Modern gemmology addresses the descriptive study of stones without relying on supernatural claims.
Natural magic: A historical tradition seeking to use hidden properties of nature for practical effects. Stone powers were often treated as part of nature's concealed, usable properties.
Marbode of Rennes: A French medieval poet and bishop, best known for a Latin verse work on gemstones. His influential poem De lapidibus shaped medieval writing about the powers of gems.
Lithotherapy: The practice of claiming that stones can promote health or well-being through their use or presence. Healing claims are a recurring subject in lapidary descriptions.
