Historical Definition

Ludus is a medicine that cures the stone by dissolving it.

Meaning

The action specified is dissolution, not simply the removal of pain or the expulsion of an intact stone. The headword gives a claimed therapeutic effect without naming the material from which the medicine is made.

Use in the Book

Magneticus tartarus and Marmoreus tartarus describe stones within the human body through their hardness or structure. These entries give readers the setting in which stone-language can be medical, rather than referring only to minerals outside the body.

Places to Read

Magneticus tartarus. A bodily stone described by hardness and a spongy structure.

Marmoreus tartarus. A bodily stone distinguished through a comparison with marble.
