The magic rites are divided into oral (spells) and manual (sympathetic rites or symbolic rites, sacrificial rites, healing rites, purification rites), complementary to each other. These rites present a recitative part, λόγος, with formulas and spells, and an operational part, πρᾶξις, with particular gestures, tools and substances. In both cases the word is fundamental because it is the magic tool par excellence, thanks to its evocative and expressive power: it is a creative and pragmatic force that acts directly on reality. This act of speech is expressed either through simple pronunciation, as in the case of oral spells, or through writing, generally on particular objects. The study will attempt investigate the power of the logos in magic rites, the ritual formulas and the different types of written objects.
