acta, or legal texts, documents, etc., generally engraved on bronze in cramped and careless capitals. Palaeography inherits both these types. Reproduced by scribes on papyrus or parchment, the elegant characters of the inscriptions become the square capitals of the manuscripts, and the actuaria, as the writing of the acta is called, becomes the rustic capital. Of the many books written in square capitals, the éditions de luxe of ancient times, only a few fragments have survived, the most famous being pages from manuscripts of Virgil. The finest examples of rustic capitals, the use of which is attested by papyri of the 1st century, are to be found in manuscripts of Virgil and Terence. Neither of these forms of capital writing offers any difficulty in reading, except that no space is left between the words. Their dates are still uncertain, in spite of attempts to determine them by minute observation. The rustic capitals, more practical than the square forms, soon came into general use. This was the standard form of writing, so far as books are concerned, until the 5th century, when it was replaced by a new type, the uncial, which is discussed below. Early cursive writing While the set book-hand, in square or rustic capitals, was used for the copying of books, the writing of everyday life, letters and documents of all kinds, was in a cursive form, the oldest examples of which are provided by the graffiti on walls at Pompeii (CIL, iv), a series of waxen tablets, also discovered at Pompeii (CIL, iv, supplement), a similar series found at Verespatak in Transylvania (CIL, iii) and a number of papyri. From a study of a number of documents which exhibit transitional forms, it appears that this cursive was originally simplified capital writing. The evolution was so rapid, however, that at quite an early date the scriptura epistolaris of the Roman world can no longer be described as capitals. By the 1st century, this kind of writing began to develop the principal characteristics of two new types: the uncial and the minuscule cursive. With the coming into use of writing surfaces which were smooth, or offered little resistance, the unhampered haste of the writer altered the shape, size and position of the letters. In the earliest specimens of writing on wax, plaster or papyrus, there appears a tendency to represent several straight strokes by a single curve. The cursive
