Historical definition

Fons philosophorum is Balneum Maris.

Meaning

The definition points to another named entry rather than describing a literal spring. Balneum Mariæ includes Maris as a form used by many writers and describes a furnace arrangement containing water. That cross-reference supplies the stated interpretive route.

Use in the book

The link is a useful reminder that an apparently evocative name can lead to apparatus vocabulary. It should not be expanded into an independent philosophical solvent or natural water source merely from the word fountain. Follow the explicit bath identification before deciding what a passage intends.
