The leading features of these manuscripts will be described in the fourth and fifth chapters. At present we wish to compare them with each other for the purpose of tracing, as closely as we may, the different styles and fashions of uncial letters which prevailed from the fourth to the tenth or eleventh century of the Christian era. The varying appearance of cursive manuscripts cannot so well be seen by exhibiting their alphabets, for since each letter is for the most part joined to the others in the same word, _connected_ passages alone will afford us a correct notion of their character and general features. For the moment we are considering the uncials only. If the Rosetta stone, by its necessary avoiding of curve lines, gives only a notion of the manner adopted on stone and not in common writing, it resembles our earliest uncials at least in one respect, that the letters, being as broad as they are high, are all capable of being included within circumscribed squares. Indeed, yet earlier inscriptions are found almost totally destitute of curves, even Ο and Θ being represented by simple squares, with or without a bisecting horizontal line (see _theta_, p. 35)(29). The Herculanean papyri, however (a specimen of which we have given in Plate iv. No. 10), are much better suited than inscriptions can be for comparison with our earliest copies of Scripture(30). Nothing can well be conceived more elegant than these simply-formed graceful little letters (somewhat diminished in size perhaps by the effects of heat) running across the volume, thirty-nine lines in a column, without capitals or breaks between the words. There are scarcely any stops, no breathings, accents, or marks of any kind; only that >, < or [right-pointing triangle] are now and then found at the end of a line, to fill up the space, or to join a word or syllable with what follows. A very few abbreviations occur, such as [symbol like Pi with Rho] in the first line of our specimen, taken from Philodemus περὶ κακιῶν (Hercul. Volum. Tom. iii. Col. xx. ll. 6-15), the very manuscript to which Tischendorf compared his Cod. Friderico-Augustanus (Proleg. § 11). The papyri, buried for so many ages from A.D. 79 downwards, may probably be a century older still, since Philodemus the Epicurean was the contemporary and almost the friend of Cicero(31). Hence from three to four hundred years must have elapsed betwixt the date of the Herculanean rolls and that of our earliest Biblical manuscripts. Yet the fashion of writing changed but little during the interval, far less in every respect than in the four centuries which next followed, wherein the plain, firm, upright and square uncials were giving place to the compressed, oblong, ornamented, or even sloping forms which predominate from the seventh or eighth century downwards. While advising the reader to exercise his skill on facsimiles of _entire passages_, especially in contrasting the lines from Philodemus (No. 10)
