diaphane

Something transparent.

The corporal nature is deuided into bright and ſhining bodies, as earth and metalles: Eyther into Diaphane or tranſparent bodyes, as ayre and water.

And for man's life as the clear sparkling wine, Gladding the heart and lifting up the soul From its frail diaphane of petulant flesh, Yet whence doth flow this liquor of delight?

A woven silk stuff with transparent and colored figures.

Essence or nature as encapsulated in a mental construct.

The figure of the diaphane, "this clear crystal nature," is a person so perfect that his simple presence would do more for the world than others manage to do through their actions.

Thus dreams and daydreams, stray thoughts, and all the other products of imagination are not simply inside one human brain; some are created by the diaphane of the person who experiences them, others come form outside, but all are projected onto the astral light.
