Latin, the language of the Romans, was originally spoken only in the small region of Central Italy known as Latium. It might well have been displaced by geographically more widespread Italian tongues such as Oscan and Umbrian, but Roman conquests made it the received speech of the peninsula, and ultimately of most wealthy or educated people all over a vast empire.
Writing began in the 7th century BC, when the Latin alphabet was devised as an adaptation of the Greek letters used by the Romans Etruscan neighbours. The earliest known written Latin is on the Lapis Niger, an inscriped block of stone, found in the Forum Romanum, that probably dates from the early 6th century BC. There is no way of establishing how many Romans became literate, but written records, orders and transactions were vital to the efficient running of the Empire, while poems, plays, political and philosophical reflections, letters, prayers and graffiti provided outlets for vivid self-expression that often bring the Romans very close to us.
Commemorative inscriptions and some official decrees appeard on stone or bronze, but a variety of materials were available for other purposes. A wooden tablet with a coating of wax was particularly useful for temporary personal memoranda and school work; the metal or wooden stylus that scratched letters into the wax had a flat top that could be employed for corrections or to erase all the written content so that the tablet could be used again. However, occasion this unstable medium also seems to have served for quite important documents.
Letters and other personal statement could be written with pen and ink on thin sheets of wood. Pens were made of metal, or sharpened reeds of feathers; Roman ink, variously mixing soot, resin and cuttlefish ink, was surprisingly black and durable, as surviving documents have shown. Those who could afford it bought a much less cumbersome, paper-like material made from the papyrus reed (an Egyptian invention from which the word paper is actually derived). This was also used for Roman books, which took the form of long papyrus scrolls. A book, or part-book, was called a volumen, or roll (the origin of the English word volume); the reader held it in both hands, simultaneously rolling and unrolling it so that the text was progressively revealed. Under the Empire, parchment and and vellum (made from hides) were also used as writing surfaces, and the book with pages, or codex, began to be made, but surprisingly it never replaced the much clumsier roll.
Roman interest in books only became intense under the influence of Greek culture in the 2nd century BC, when libraries were part of the booty brought back from the East by Sulla and other successful generals. An influx of well-educated Greek slaves facilitated the development of the book trade in Rome, where something resembling mass production was achieved by booksellers whose slaves wrote out copies of texts dictated by one of their number. The influence of ardent collectors such as Cicero helped to create a fashion for possessing a private library, and booksellers flourished in the capital and ultimately in most parts of the Empire, advertising the latest authors on the pillars outside their shops. The first public library in Rome was founded during the reign of Augustus by the retired politician-poet Gaius Asinius Pollio, and within a century there were over 20, some of which allowed members to take out books for private reading. Authors were paid an outright fee for their works, and even the most famous were unable to live on their literary income. Martial for example, complained that in spite of being read even on the Danube and in Britain, his work brought him little profit. The bookseller-publisher could not afford to be generous, since there was no copyright law and consequently he could never acquire exclusive rights to any publication. As soon as he put a work on sale, a rival bookseller could acquire a copy, put his own scribes to work on it, and publish his own edition. Impecunious authors were therefore dependent on the generosity of one or more patrons and as Martial lamented, there was not a Maecenas in every generation.
