Meanwhile, however, Latin was doing more than merely furnishing the materials of the new language. The literary faculty of the Gauls was early noticed, and before their subjection had long been completed they were adepts at using the language of the conquerors. It does not fall within our plan to notice in detail the Latin literature of Gaul and early France, but the later varieties of that literature deserve some little attention, because of the influence which they undoubtedly exercised on the literary forms of the new language. In early French there is little trace of the influence of the Latin forms which we call classical. It was the forms of the language which has been said to have 'dived under ground with Naevius and come up again with Prudentius' that really influenced the youthful tongue. Ecclesiastical Latin, and especially the wonderful melody of the early Latin hymn-writers, had by far the greatest effect upon it. Ingenious and not wholly groundless efforts have been made to trace the principal forms of early French writing to the services and service-books of the church, the chronicle to the sacred histories, the lyric to the psalm and the hymn, the mystery to the elaborate and dramatic ritual of the church. The _Chanson de Geste_, indeed, displays in its matter and style many traces of Germanic origin, but the metre with its regular iambic cadence and its rigid caesura testifies to Latin influence. The service thus performed to the literature was not unlike the service performed to the language. In the one case the scaffolding, or rather the skeleton, was furnished in the shape of grammar; in the other a similar skeleton, in the shape of prosody, was supplied. Important additions were indeed made by the fresh elements introduced. Rhyme Latin had itself acquired. But of the musical refrains which are among the most charming features of early French lyric poetry we find no vestige in the older tongue. [Sidenote: Early Monuments.]
