every book belongs its copy." The Battle of Cúl Dreimhne was fought over this issue. Modern copyright law has been influenced by an array of older legal rights that have been recognized throughout history, including the moral rights of the author who created a work, the economic rights of a benefactor who paid to have a copy made, the property rights of the individual owner of a copy, and a sovereign's right to censor and to regulate the printing industry. The origins of some of these rights can be traced back to ancient Greek culture, ancient Jewish law, and ancient Roman law. In Greek society, during the sixth century B.C.E., there emerged the notion of the individual self, including personal ideals, ambition, and creativity. The individual self is important in copyright because it distinguishes the creativity produced by an individual from the rest of society. In ancient Jewish Talmudic law there can be found recognition of the moral rights of the author and the economic or property rights of an author. Prior to the invention of movable type in the West in the mid-15th century, texts were copied by hand and the small number of texts generated few occasions for these rights to be tested. During the Roman Empire, a period of prosperous book trade, no copyright or similar regulations existed, copying by those other than professional booksellers was rare. This is because books were, typically, copied by literate slaves, who were expensive to buy and maintain. Thus, any copier would have had to pay much the same expense as a professional publisher. Roman book sellers would sometimes pay a well-regarded author for first access to a text for copying, but they had no exclusive rights to a work and authors were not normally paid anything for their work. Martial, in his Epigrams, complains about receiving no profit despite the popularity of his poetry throughout the Roman Empire. The printing press came into use in Europe in the 1400s and 1500s, and made it much cheaper to produce books. As there was initially no copyright law, anyone could buy or rent a press and print any text. Popular new works were immediately re-set and re-published by competitors, so printers needed a constant stream of new material. Fees paid to authors for new works were high, and significantly supplemented the incomes of many academics. Printing brought profound social changes. The rise
