The oldest document in the Spanish language with an ascertained date is a confirmation by Alfonso the Seventh, in the year 1155, of a charter of regulations and privileges granted to the city of Avilés in Asturias.[6] It is important, not only because it exhibits the new dialect just emerging from the corrupted Latin, little or not at all affected by the Arabic infused into it in the southern provinces, but because it is believed to be among the very oldest documents ever written in Spanish, since there is no good reason to suppose that language to have existed in a written form even half a century earlier. [6] See Appendix (A.), on the History of the Spanish Language. How far we can go back towards the first appearance of poetry in this Spanish, or, as it was oftener called, Castilian, dialect is not so precisely ascertained; but we know that we can trace Castilian verse to a period surprisingly near the date of the document of Avilés. It is, too, a remarkable circumstance, that we can thus trace it by works both long and interesting; for, though ballads, and the other forms of popular poetry, by which we mark indistinctly the beginning of almost every other literature, are abundant in the Spanish, we are not obliged to resort to them, at the outset of our inquiries, since other obvious and decisive monuments present themselves at once. * * * * * The first of these monuments in age, and the first in importance, is the poem commonly called, with primitive simplicity and directness, “The Poem of the Cid.” It consists of above three thousand lines, and can hardly have been composed later than the year 1200. Its subject, as its name implies, is taken from among the adventures of the Cid, the great popular hero of the chivalrous age of Spain; and the whole tone of its manners and feelings is in sympathy with the contest between the Moors and the Christians, in which the Cid bore so great a part, and which was still going on with undiminished violence at the period when the poem was written. It has, therefore, a national bearing and a national character throughout.[7]
