I cannot even hint what it was like, for it was a compound of all that is unclean, uncanny, unwelcome, abnormal, and detestable. It was the ghoulish shade of decay, antiquity, and dissolution; the putrid, dripping eidolon of unwholesome revelation, the awful baring of that which the merciful earth should always hide. God knows it was not of this world - or no longer of this world - yet to my horror I saw in its eaten-away and bone-revealing outlines a leering, abhorrent travesty on the human shape; and in its mouldy, disintegrating apparel an unspeakable quality that chilled me even more.

From "The Outsider" by H.P. Lovecraft
