Mani's illustration of "Sun and Shadow."

For (as regards) the Sun and the Shadow which touch one another, the nature of the Sun has no [gross and dense] body . . . to destroy the Shadow, and the Light which is here . . . seeing that no other body is interposed. [L. 38.] Moreover, a Shadow is not a nature (in) itself. For it is the child of that substance, either of stone or wood, standing in the [P. 99.] [lxxviii] face of the Light; and apart from the Light a Shadow cannot be produced.
