    • Refract To break the natural course of, as rays of light orr heat, when passing from one transparent medium to another of different density; to cause to deviate from a direct course by an action distinct from reflection; as, a dense medium refrcts the rays of light as they pass into it from a rare medium.

And we who see them but a lens
Refracting heavenly light?—

How red my setting sun appears,
How lurid looks this soul of mine!

But it is choked with nettles and obscene
And phallic fungi rot there as they grow.
