From the perspective of semiotics, or a science of signs, communication exceeds the usual verbal mode of expression and covers extra linguistic modes. This paper addresses a specific communicative system represented by Tarot pictures. The semiotic approach not only presents Tarot as exceeding its function as a game but also de-mystifies, in part. its occult side by virtue ofthe analysis of semiosis, or the action of signs in nature. Using references from the Hermetic philosophy, to Dummett, to Peirce, to Smolin, the paper asserts that, should we understand the language of signs, the memories of past and future events would be accessible to human reason.
