"Know I am sent To show thee what shall come in future days To thee and to thy offspring; good with bad Expect to hear, supernal grace contending With sinfulness of men; thereby to learn True patience, and to temper joy with fear, And pious sorrow, equally inured By moderation either state to bear, Prosperous or adverse: so shalt thou lead Safest thy life, and best prepared endure Thy mortal passage when it comes. Ascend This hill; let Eve (for I have drenched her eyes) Here sleep below, while thou to foresight wakest. As once thou slept'st, while she to life was formed." From a hill in Paradise,--after purging Adam's eyes with three drops of water from the well of life,--Michael vouchsafes him a glimpse of all that is to take place upon our earth. Thus, Cain and Abel first pass before their father's eyes, but death is so unintelligible to Adam that the angel has to explain what it means. Overwhelmed at the thought that so awful a thing has come into the world through his transgression, Adam is further horrified when the angel reveals all the suffering which will visit mankind, explaining that, since much of it will be due to evil living, it behooves Adam to observe temperance in food and drink. But he warns him that, in spite of all precautions, old age will come upon him as a precursor of death. In a panorama Adam sees all that is to occur until the Deluge, and, watching Noah construct the ark, wails because his progeny is to be destroyed by the flood. The angel, however, demonstrates that the righteous will be saved and that from them will descend a race more willing to obey God's commands. The dove and the rainbow, therefore, instil comfort into Adam's heart, as does God's promise that day and night, seedtime and harvest shall hold their course until new heavens and earth appear wherein the just shall dwell. _Book XII._ Having depicted a world destroyed and foreshadowed a world restored, the angel shows Adam how man will migrate to a plain, where by means of bricks and bitumen an attempt will be made to erect a tower to reach heaven. When Adam expresses displeasure that one of his race should defy God, Michael assures him he rightly abhors disobedience, and comforts him by revealing how one righteous man, in whose "seed all nations shall be blest," is to be brought out of that country into the Promised Land. Not only does the angel name Abraham, but depicts his life, the captivity in Egypt, the exodus, and the forty years in the desert. He also vouchsafes to Adam a glimpse of Moses on Mount Sinai receiving the tables of the law, and appointing the worship which the Chosen People are to offer to their Creator. When Adam wonders at the number of laws, Michael rejoins that sin has many faces, and that until blood more precious than that of the prescribed sacrifices has been shed, no suitable atonement can be made.
