But now we may remark the steady progress of these monsters to the bounds of their mythological habitat. There came a time when Behemoth and Leviathan were hardly more presentable than other personified horrors. They too must 'take the veil,'--a period in the history of mythical, corresponding to extinction in that of actual, monsters. The following passage in the Book of Enoch is believed by Professor Drummond to be a later insertion, probably from the Book of Noah, and as early as the middle of the first century:--'In that day two monsters shall be divided; a female monster named Leviathan, to dwell in the abyss of the sea, above the sources of the waters; but the male is called Behemoth, which occupies with its breast a desolate wilderness named Dendain, on the east of the garden where the elect and righteous dwell, where my grandfather (Enoch) was taken up, being the seventh from Adam, the first man whom the Lord of the spirits created. And I asked that other angel to show me the might of these monsters, how they were separated in one day, and one was set in the depth of the sea, the other on the firm land of the wilderness. And he spoke to me, 'Thou son of man, thou desirest in this to know what has been concealed.' And the other angel who went with me, and showed me what is in concealment, spake, ... 'These two monsters are prepared conformably to the greatness of God to be fed, in order that the penal judgment of God may not be in vain.' [254] We may thus see that there were antecedents to the sentiment of Aquinas,--'Beati in regno coelesti videbunt poenas damnatorum, ut beatitudo illis magis complaceat.' Or, perhaps, one might say rather to the logic of Aquinas; for though he saw that it would be necessary for souls in bliss to be happy at vision of the damned or else deficient in bliss, it is said he could hardly be happy from thinking of the irreversible doom of Satan himself. It would appear that only the followers of the Genevan who anticipated his god's hell for Servetus managed to adapt their hearts to such logic, and glory in the endless tortures of their fellow-creatures.
