A). Σ ς B. 2 ), eighteenth letter in the Etruscan abecedaria ( IG 14.2420 ) and probably in the oldest Gr. alphabets, occupying the same serial position as the Hebrew Tsade (<*>, Phoenician <*> <*> Syria 6.103 ), with which it may be identified. In many of the oldest Gr. alphabets it represents the sound s, for which <*> and <*> (twenty-first letter in the Etruscan abecedaria) is an alternative representation preferred in other Gr. alphabets. It is uncertain whether the letter <*> (name and serial position unknown), which represents the sound σς in Schwyzer 707 (Ephesus, vi B.C.), 701 A 17 (Erythrae, v B.C.), SIG 4.6 (Cyzicus, vi B.C.), 45.2 , al. (Halic., v B.C.) and the third sound (σς?) in the name of Mesambria in BMus.Cat.Coins Thrace p.132 , is to be identified with Μ.

0-0).It is also uncertain whether the numerical symbol <*>(= 900 ), described by Gal. 17(1).525 , which has this form in PEleph. 1 (iv B.C.), PCair.Zen. 22.5 (iii B.C.), Rev.Phil. 35.138 (Thessaly, iii B.C.), Milet. 6.39 (ii B.C.), where it forms part of a symbol for thousands, and later the forms Τ JHS 26.287 (Athenian tesserae of iv B.C.), 25.342 (papyri of ii B.C.), SIG 695.83 ( Magn. Mae., ii B.C.), IG 12(1).913 (Rhodes, i B.C.), <*> ib. 22.2776.11 , al. (ii A.D.), and <*> (medieval Mss., called παρακύϊσμα in Sch. D.T. p.496 H.), is to be identified with either of the foregoing. The numerical symbol, in the form <*>, follows ω in an Attic abecedarium, Bullettino dell' Inst. di corrisp. archeol. 1867.75 , and that position tallies with its numerical value, since ω = 800 . The extended alphabet used by Archim. Spir. 11 , Aequil. 2.3 for a diagram ends with ω <*>.
