SAMECH
Text: The 15th Hebrew letter, Samech (X), means a prop, a strong support. In Greek as in Hebrew X stands before O and there is said to be a valid Kabbalistic reason for this occurrence and recurrence of priority. An ancient Judaic tradition connects X with Cochab, a star, sometimes a comet. Treatises on alchemy abound in references to this letter, which for some reason is treated as one of far greater than average importance.
