'The letter is concerned with the chronology of the Seleucid era, starting from a coin of Antioch dated ЄΤΟΥΣ ΖΟΡ with the letter Γ. The coin of Antioch is described and a drawing is attached (f.234), together with a drawing of the coin of Cadi, although the latter was not mentioned in the letter. Presumably the Antioch coin was also in Covel’s possession.' (Burnett 2020b, p. 588)
