At the library it was easy to find good manuals of palaeography, and over these the two men puzzled till the lights of evening shone out from the great chandelier. In the end they found what was needed. The letters were indeed no fantastic invention, but the normal script of a very dark period. They were the pointed Saxon minuscules of the eighth or ninth century A.D., and brought with them memories of an uncouth time when under a fresh Christian veneer ancient faiths and ancient rites stirred stealthily, and the pale moon of Britain looked sometimes on strange deeds in the Roman ruins of Caerleon and Hexhaus, and by the Towers along Hadrian's crumbling wali. The words were in such Latin as a barbarous age might remember—"Corwinus necandus est. Cadaver aq(ua) forti dissolvendum, nec aliq(ui)d retinendum. Tace ut potes."—which may roughly be translated, "Curwen must be killed. The body must be dissolved in aqua fortis, nor must anything be retained. Keep silence as best you are able."
