The attalid letters from Pessinous are exceptionnal documents for Antiquity, because of their secret nature. They allow the reconstitution of a tragic episod which affected the sanctuary: a sacrilege commited by Galatians. Facing the accident, the author of these texts expresses reactions rarely noticed, linked with theology. It may be added that the presentations of these events became possible by the simple change concerning the word Pessongoi, which figures in the beginning of the first letter.
