Clement on Orpheus

I've been looking at Elizabeth Henry's book, Orpheus with his Lute: Poetry and the Renewal of Life. She covers a wide range material relating to Orpheus but I was interested to read her discussion of Clement of Alexandria:

The bringer of [...] spiritual liberation and health must, in the early Christian age, have appeared to possess either divine grace or magical powers. The perplexity of a devout Christian is seen in the writings of Clement of Alexandria, on other Greek myths and cultic heroes as well as the Orpheus story. In his Stromata (Miscellanies) of about 200 AD Clement speaks of 'Orpheus the theologian' as one who (like Plato) 'prepared the way' for the Gospel. Such Greek teachers were at this time declared by Clement to be prophets in direct line of descent from Moses. The status of Orpheus is not the equivalence with Christ which we find many centuries later in the Morte Christi celebrata, but that of 'prefiguration', as a divinely sent forerunner who was to show the nature of the Christ to come. This position was not easily maintained, as Clement's (apparently) later Protrepticon (Exhortation to the Greeks) makes clear. This work was a reply to the attack on Christianity by the Platonist Celsus, also of Alexandria, in which he declared Orpheus more worthy of worship than Jesus Christ. The vehemence of Clement's reply is itself a witness to the continuing potency of the Orphean figura:

"A Thracian, cunning master of his art (he also is the subject of a Hellenic legend) tamed the wild beasts by the mere might of song, and transplanted trees - oaks - by music ... How, let me ask, have you believed vain fables, and supposed animals to be charmed by music, while Truth's shining face alone is looked on with credulous eyes? ... To me that Thracian Orpheus seems to have been a deceiver ... enticing men to idols ... But not such is the song of Christ, which has come to loose the bitter bond of tyrannising demons. It alone has tamed men, the most intractable of animals; the frivolous among them answer to the fowls of the air, deceivers to reptiles, the irascible to lions, the voluptuous to swine, the rapacious to wolves. The silly are stocks and stones ... Behold the might of the new song! It has made men out of stones, men out of beasts. Those that were as dead, not being partakers of the new life, have come to the true life, simply by becoming listeners to this song."

I'm interested in this image of the 'song of Christ', especially the moment where Clement says 'Behold the might of the new song!'
