Calumny creates oceans, scales, mountains and traverses deserts with greater ease than the Scythian Abarls and like him rides upon a poisoned arrow. (C.C.Colton)
Calumny requires no proof. The throwing out of malicious imputations against character leaves a stain, which no after refutation can wipe out. The imagination is of so delicate a structure that even words wound it. (William Hazli)
