universal. Peter Lombard and Hugo of St. Victor, authorities of vast weight, gave it their sanction in the twelfth century, and impressed it for ages upon the mind of the Church. Both these lines of speculation--as to the creation of everything out of nothing, and the reconciling of the instantaneous creation of the universe with its creation in six days--were still further developed by other great thinkers of the Middle Ages. St. Hilary of Poictiers reconciled the two conceptions as follows: "For, although according to Moses there is an appearance of regular order in the fixing of the firmament, the laying bare of the dry land, the gathering together of the waters, the formation of the heavenly bodies, and the arising of living things from land and water, yet the creation of the heavens, earth, and other elements is seen to be the work of a single moment." St. Thomas Aquinas drew from St. Augustine a subtle distinction which for ages eased the difficulties in the case: he taught in effect that God created the substance of things in a moment, but gave to the work of separating, shaping, and adorning this creation, six days.(5) (5) For Philo Judaeus, see his Creation of the World, chap. iii; for St. Augustine on the powers of numbers in creation, see his De Genesi ad Litteram iv, chap. ii; for Peter Lombard, see the Sententiae, lib. ii, dist. xv, 5; and for Hugo of St. Victor, see De Sacrementis, lib i, pars i; also, Annotat, Elucidat in Pentateuchum, cap. v, vi, vii; for St. Hilary, see De Trinitate, lib. xii; for St. Thomas Aquinas, see his Summa Theologica, quest lxxxiv, arts. i and ii; the passage in the Nuremberg Chronicle, 1493, is in fol. iii; for Vousset, see his Discours sur l'Histoire Universelle; for the sacredness of the number seven among
