However, the Arabic _Diwan_――that is to say, the poetic collection of that nation, goes back to most ancient times. One finds in it verses attributed to the first Hebrew patriarchs and even to Adam[217]; for since the introduction of Islamism, the cosmogony of Moses has become that of the Mussulmans, as it has been ours since the establishment of Christianity. It is there, in this _diwan_, that the most authentic traditions are preserved: they are all in verse and resemble greatly, as to form and doubtless as to substance, that which the monk of St. André has transmitted to us through the court of Charlemagne. It is the same chivalrous spirit and the same romantic fictions. The Persian poet Firdausi appears to have followed similar traditions concerning the ancient kings of Iran, in his famous poem entitled _Shah-Namah_.[218] The wonders which reign in these traditions have been transmitted no doubt by the Arabs, with the artifice of rhyme: both have the same spirit. The protecting fairies of the knights, the giant persecutors of ladies, the enchanters, the magic, and all those illusions are the fruits of that brilliant and dreamy imagination which characterizes the modern Orientals. We have enthusiastically enjoyed them in the depths of the barbarity where we were plunged; we have allowed ourselves to be drawn by the charms of rhyme, like children in the cradle, whom their nurses put to sleep by the monotonous sound of a lullaby. Escaped from that state of languor, and struck at last with a gleam of real intelligence, we have compared Greece and Arabia, the songs of epopœia and those of the ballads; we have blushed at our choice; we have wished to change it; but owing to the captivating form always more or less the substance, we have only succeeded in making mixtures more or less happy, according to the secondary mode that we follow.
