Dim, dubious, bat-like creatures seemed to be flitting to and fro between one of the stone vats and the group that toiled like sculptors, clothing the bony foot with a reddish plasm which they applied and moulded like so much clay. Gaspard thought, but was not certain later, that this plasm, which gleamed as if with mingled blood and fire, was being brought from the rosy-litten vat in vessels borne by the claws of the shadowy flying creatures. None of them, however, approached the other vat, whose wannish light was momently enfeebled, as if it were dying down. –Clark Ashton Smith (The Colossus of Ylourgne)
