That other cantares relating to the Cid existed is positively known through the researches of Señor Don Ramón Menéndez Pidal, who has demonstrated that one of them was used in the most ancient version of the Crónica General, of which three recensions evidently existed at different periods, and it is now clear that the passage in question does not come from the Poema as we have it, as was formerly believed. [27] The passages on the Cid in the second version of the Crónica are also derived from still another cantar on the popular hero, known as the Crónica Rimada, [28] or Cantar de Rodrigo, evidently the work of a juglar of Palencia, and which seems to be a mélange of several lost cantares relating to the Cid, as well as to other Spanish traditions. This version, however, is much later than the Poema, and is chiefly interesting as enshrining many traditions relative to the Cid as well as to the ancient folk-tales of Spain. Metre of the "Poema del Cid" It would certainly seem as if, like all cantares, the poem had been especially written for public recitation. The expression "O señores," encountered in places, may be taken as the equivalent of the English "Listen, lordings," of such frequent occurrence in our own lays and romances, which was intended to appeal to the attention or spur the flagging interest of a medieval audience. The metre in which the poem is written is almost as unequal as its poetic quality. The prevailing line is the Alexandrine or fourteen-syllabled verse, but some lines run far over this average, while others are truncated in barbarous fashion, probably through the inattention or haste of the copyist. [29] It seems to me that the Poema, although of the highest merit in many of its finest passages, has received the most extravagant eulogy, and I suspect that many of the English critics who descant so glibly upon its excellences have never perused it in its entirety. Considerable tracts of it are of the most pedestrian description, and in places it descends to a doggerel which recalls the metrical barbarities of the pantomime. But when the war-trump gives him the key it arouses the singer as it arouses Scott--the parallel is an apt and almost exact one--and it is a mighty orchestra indeed which breaks upon our ears. The lines surge and swell in true Homeric tempest-sound, and as we listen to the crash of Castilian spears upon the Moorish ranks we are reminded of those sounding lines in Swinburne's Erechtheus beginning: With a trampling of drenched, red hoofs and an earthquake of men that meet, Strong war sets hand to the scythe, and the furrows take fire from his feet.
