“A strange and horrible darkness fell upon me.”

Giovanni Benedetto Castiglione (called il Grechetto), Melancholia (ca. 1640)

“While I traversed the apartment in the most horrible dismay of soul, expecting every moment that the earth would open and swallow me up, my conscience scaring me…and the city of refuge out of reach and out of sight, a strange and horrible darkness fell upon me. If it were possible that a heavy blow could light upon the brain without touching the skull, such was the sensation I felt. I clapped my hand to my forehead, and cried aloud through the pain it gave me. At every stroke my thoughts and expressions became more wild and indistinct…These thoughts kept undisturbed possession of my mind all the way through my illness, without interruption or abatement.”

—William Cowper, “Memoir of the Early Life of William Cowper, Esq.” (1835)
