The separation between the official and aristocratic language and that of the lower classes in such distinct regions, became the more palpable and determined, as the traditional glory of Imperial Rome waned. One Imperial Latin was spoken in the laws, tribunals, and schools, in the forum, the temple, and the palace; a common idiom bound together the educated classes of the vast Roman Empire; but in the business houses and the workshops, among the slaves and the lower classes, there was no common tongue; each country had its local expressions and its dialects, of which--though Latin was the foundation--a great part consisted of Latinised forms, and words of diverse origin--sometimes native, sometimes exotic--here Celtic, there Iberic, yonder Breton or Arabic, as the case might be. Later, when Roman fame and influence had declined still further, when the old Roman families had sunk to a plebeian level, and their place had been taken by a new, locally produced aristocracy, then it was that, along with the toga and the sword, the grand old Latin language disappeared for ever, leaving in its place a mixed dialect, which we call “Romance.”[77] The various provinces of the Roman Empire during its last period were, without doubt, bi-lingual. The conquerors adopted, as is invariably the case, the language and customs of the conquered, and forgot their own. Valmar remarks that Amador de los Rios was right in saying that the common idiom of the peninsula was already completely formed at the beginning of the twelfth century. There are popular couplets written in the language of Galicia which can be traced back to the year 1110, namely the couplets that were sung on the occasion of the enthusiastic welcome given by the townspeople of Santiago to Bishop Gelmirez, who in 1105 had founded there a school for the cultivation of oratory, letters, _and the Latin tongue_. It is true, as Valmar points out, that the formation of the languages of Castille and Galicia must have required centuries, but that formation reached its completion towards the middle of the twelfth century. When new dialects came into existence, the synthetic beauty so remarkable in the Latin language was lost, but in its place animation and ease of expression were gained. “Marriages,” says Valmar, “also helped on the triumph of the Romance languages; but perhaps the most powerful influence was Christ’s religion of charity and love.” Even in Italy Latin gradually became an unknown tongue to the lower classes. Pope Boniface VIII. translated the _Stabat Mater_ into the young Italian language that the people might be able to appreciate it.
