_Zeta_ on the Rosetta stone maintains its old form ([Symbol rather like a Roman capital I]), which is indeed but the next letter reversed. In manuscripts it receives its usual modern shape (Z), the ends being pointed decidedly, slightly, or not at all, much after the manner described for _epsilon_. In old copies the lower horizontal line is a trifle curved (Cod. R, No. 5), or even both the extreme lines (Cod. Z, No. 6, and Cod. Augiensis of St. Paul). In such late books as Parham 18 (A.D. 980, facsim. No. 36) _Zeta_ is so large as to run far below the line, ending in a kind of tail. _Eta_ does not depart from its normal shape (Η) except that in Cod. Ephraemi (No. 24) and some narrow and late uncials (e.g. Nos. 7, 36) the cross line is often more than half way up the letter. In a few later uncials the cross line passes _outside_ the two perpendiculars, as in the Cod. Augiensis, twenty-six times on the photographed page of Scrivener’s edition. _Theta_ deserves close attention. In some early inscriptions it is found as a square, bisected horizontally ([Symbol]). On the Rosetta stone and most others (but only in such monuments) it is a circle, with a strong central _point_. On the Herculanean rolls the central point is spread into a short horizontal line, yet not reaching the circumference (No. 10, l. 8). Thence in our uncials from the fourth to the sixth century the line becomes a horizontal diameter to a true circle (Codd. Vatican., Sinait., Codd. ANRZ, Ephraemi, Claromont., Rossanensis, and Cureton’s Homer). In the seventh century the diameter began to pass out of the circle on both sides: thence the circle came to be compressed into an ellipse (sometimes very narrow), and the ends of the minor axis to be ornamented with knobs, as in Cod. B of the Apocalypse (eighth century), Cod. Augiensis (ninth century), LX of the Gospels, after the manner of the tenth century (Nos. 7, 16, 21, 36, 38).
