“Light that makes things seen, makes some things invisible. Were it not for darkness and the shadow of the earth, the noblest part of the Creation had remained unseen, and the stars in heaven invisible… Life itself is but the shadow of death, and souls departed are but the shadows of the living. All things fall under this name. The sun itself is but the dark simulacrum, and light but the shadow of God.”

– Sir Thomas Browne, The Eclectic Review
