The disposition of the letters is as follows: s a t o r a r e p o t e n e t o p e r a r o t a s This charm has been preserved for us in Greek and Coptic as well as in Roman characters, and examples of it have been found cut in a marble slab above the chapel of St. Laurent at Rochemaur (Ardèche), France, and also in the plaster wall of an old Roman house at Cirncester, Gloucestershire, England. In a Greek manuscript in the Bibliothèque Nationale, in Paris,[578] the Latin words are transliterated and translated as follows: σάτορ, the sower ἀρεπο, the plough τένετ, holds ὀπερα, works ρότας, wheels Another and more ingenious explanation of this puzzle has, however, been given.[579] Beginning with the last word “rotas,” and taking the other words in their order, it is proposed to read as follows: “The plough-wheels (rotas), the laborer (opera), holds (tenet), creep after him (arepo), I, the sower (sator).” The chief defect in this version appears to be the assumption that “opera” can be rendered “laborer,” an interpretation which is, at best, supported by a doubtful use of the word in that sense by Horace. This charm appears in an Italian manuscript of the fourteenth century,[580] where it is recommended to be used for the assurance of a speedy delivery. Touching the wonderful and mystic power attributed to the seven vowels of the Greek alphabet by the Gnostics, C. W. King cites the following words from the Pistis Sophia of Valentinus:[581] Nothing therefore is more excellent than the mysteries which ye seek after, saving only the mystery of the Seven Vowels and their forty and nine Powers, and the Numbers thereof. And no name is more excellent than all these [Vowels], a Name wherein be contained all Names and all Lights and all Powers.
