LIVRE. The livre is an obsolete French monetary unit and weight, the word being derived from the Latin "libra," a pound used as money; it was called the livre (Tournois) and was divided into 20 "sous" of 12 "deniers" each. This corresponds to the present English system of pounds, shillings and pence, each con taining that weight of silver. Originally equal to the English pound, it early depreciated to a far greater extent. Thus the franc, whose name dates from the middle ages, circulated before the Revolution by the side of the livre, and the legal rate of conversion was that of 81 livres to 8o francs.
After the Revolution the franc became the official monetary unit, but the livre continued to circulate until 1834, when it was withdrawn.
As a measure of weight, the livre was of an indefinite character, each town having its own standard.
We have some testimony to Livy's studies in rhetoric (Quintil. x. 1.39 "that brevity which is found in Livy in a letter written to his son: Read Demosthenes and Cicero, then other authors as each is likest to Demosthenes and Cicero," cf. ii. 5.2o, viii. 2,18) and philosophy (Seneca, Ep. 100.9 "You may add the name of Titus Livius: for he wrote both dialogues assignable as well to history as to philosophy, and other books avowedly containing philosophy"). But his life-work was history.
His History of Rome (Ab urbe condita libri) was in 142 hooks, and told the story of Rome from the arrival of Aeneas in Italy down to the death of Drusus, younger brother of the emperor Tiberius, in A.D. 9. There are indications that the work was pub lished in parts: thus, while Bk. I. opens with a formal preface to the whole work, prefaces of a less formal nature introduce Bks. VI., XXI. and XXXI. The division into decades is a late one and is not heard of before the end of the 5th century, though some scholars have seen what they consider to be traces of an original decadic division, e.g., Bk. LXXX. contained the death of Marius, Bk. XC. the death of Sulla.
Of the 142 books only 35 are extant, viz., I.–X., carrying the story down to 293 B.C. XXI.–XLV. (with some lacunae in XLI.–XLIV.), covering the years 218-167 B.C. We have, further, a fragment of Bk. XCI. which was discovered in the Vatican in 1772. The lost books are to some extent replaced by the Periochae (or summaries of contents), dating perhaps from the 4th century, which we possess for all the books with the exception of CXXXVI. and CXXXVII. Further, the Prodigia of Iulius Obsequens (4th century A.D.) which gives a list of prodigies from 19o-12 B.C., is directly taken from (probably an epitome of) Livy. The same applies to the fasti in the Chronica of Cassiodorus (6th century). An Oxyrhynchus papyrus (for which see J. S. Reid, Classical Review, July 1904) contains fragments of an epitome—excerpts from Bks. XXXVII.–XL. and XLVIII.–LV. Lastly, the sub stance of much of Livy's history is no doubt to be found in later writers, who made use of his work.
