For the seven-day week among the Chaldeans and rest on the seventh day, and the proof that even the name "Sabbath" is of Chaldean origin, see Delitzsch, Beiga-ben zu Smith's Chald. Genesis, pp. 300 and 306; also Schrader; for St. Basil, see Hexaemeron and Homilies vii-ix; but for the steadfastness of Basil's view in regard to the immutability of species, see a Catholic writer on evolution and Faith in the Dublin Review for July, 1871, p. 13; for citations of St. Augustine on Genesis, see the De Genesi contra Manichoeos, lib. ii, cap. 14, in Migne, xxxiv, 188,--lib. v, cap. 5 and cap. 23,--and lib vii, cap I; for the citations from his work on the Trinity, see his De Trinitate, lib. iii, cap. 8 and 9, in Migne, xlii, 877, 878; for the general subject very fully and adequately presented, see Osborn, From the Greeks to Darwin, New York, 1894, chaps. ii and iii. This idea of a development by secondary causes apart from the original creation was helped in its growth by a theological exigency. More and more, as the organic world was observed, the vast multitude of petty animals, winged creatures, and "creeping things" was felt to be a strain upon the sacred narrative. More and more it became difficult to reconcile the dignity of the Almighty with his work in bringing each of these creatures before Adam to be named; or to reconcile the human limitations of Adam with his work in naming "every living creature"; or to reconcile the dimensions of Noah's ark with the space required for preserving all of them, and the food of all sorts necessary for their sustenance, whether they were admitted by twos, as stated in one scriptural account, or by sevens, as stated in the other. The inadequate size of the ark gave especial trouble. Origen had dealt with it by suggesting that the cubit was six times greater than had been supposed. Bede explained Noah's ability to complete so large a vessel by supposing that he worked upon it during a hundred years; and, as to the provision of food taken into it, he declared that there was no need of a supply for more than one day, since God could throw the animals into a deep sleep or otherwise miraculously make one day's supply sufficient; he also lessened the strain on faith still more by diminishing the number of animals taken into the ark--supporting his view upon Augustine's theory of the later development of insects out of carrion.
