Alchemy across periods: keep the layers visible.
Materials, recipes, textual traditions, and later interpretations need distinct historical settings.
Start with a historical survey
The Oxford chapters introduce long-term alchemical history and the sacred art of alchemy. They are scholarly orientations to a field with changing practices and meanings. Oxford Handbook of Science and Medicine in the Classical World ↗

Follow a concrete operation
Track a recipe or term through dated editions and witnesses. Shared vocabulary alone cannot establish uninterrupted transmission across centuries. Oxford Handbook of Science and Medicine in the Classical World ↗
