It is impossible to say for certain whether Laurence's translation of the whole of the _Book of Enoch_ had come under Byron's notice before he planned his new "Mystery," but it is plain that he was, at any rate, familiar with the well-known fragment, "Concerning the 'Watchers'" [Περὶ των Ἐγρηγόρων [Peri\ tôn E)grêgo/rôn]], which is preserved in the _Chronographia_ of Georgius Syncellus, and was first printed by J. J. Scaliger in _Thes. temp. Euseb._ in 1606. In the prophecy of the Deluge to which he alludes (_vide post_, p. 302, note 1), the names of the delinquent seraphs (Semjâzâ and Azâzêl), and of the archangelic monitor Raphael, are to be found in the fragment. The germ of _Heaven and Earth_ is not in the _Book of Genesis_, but in the _Book of Enoch_. Medwin, who prints (_Conversations_, 1824, pp. 234-238) what purports to be the prose sketch of a Second Part of _Heaven and Earth_ (he says that Byron compared it to Coleridge's promised conclusion of _Christabel_--"that, and nothing more!"), detects two other strains in the composition of the "Mystery," an echo of Goethe's Faust and a "movement" which recalls the _Eumenides_ of Æschylus. Byron told Murray that his fourth tragedy was "more lyrical and Greek" than he at first intended, and there is no doubt that with the _Prometheus Vinctus_ he was familiar, if not at first hand, at least through the medium of Shelley's rendering. But apart from the "Greek choruses," which "Shelley made such a fuss about," Byron was acquainted with, and was not untouched by, the metrical peculiarities of the _Curse of Kehama_, and might have traced a kinship between his "angels" and Southey's "Glendoveers," to say nothing of _their_ collaterals, the "glumms" and "gawreys" of _Peter Wilkins_ (see notes to Southey's _Curse of Kehama_, Canto VI., _Poetical Works_, 1838, viii. 231-233). Goethe was interested in _Heaven and Earth_. "He preferred it," says Crabb Robinson (_Diary_, 1869, ii. 434), "to all the other serious poems of Byron.... 'A bishop,' he exclaimed, though it sounded almost like satire, 'might have written it.' Goethe must have been thinking of a _German_ bishop!" (For his daughter-in-law's translation of the speeches of Anah and Aholibamah with their seraph-lovers, see _Goethe-Jahrbuch_, 1899, pp. 18-21 [Letters, 1901, v. Appendix II. p. 518].) _Heaven and Earth_ was reviewed by Jeffrey in the _Edinburgh Review_, February, 1823, vol. 38, pp. 42-48; by Wilson in _Blackwood's Edinburgh Magazine_, January, 1823, vol. xiii. pp. 71, 72; and in the _New Monthly Magazine_, N.S., 1823, vol. 7, pp. 353-358.
