Lvcretivs II. 263 ‘nonne uides etiam patefactos tempore puncto.’ ‘Tempore puncto’ occurs only here in Lucretius and in no other author; but ‘puncto tempore’ is read in II. 456, 1006, IV. 214; ‘puncto in tempore et,’ VI. 230. ‘Temporis puncto’ is found at I. 1109, and ‘temporis in puncto’ at IV. 164, 193. ‘Puncto… diei’ occurs in IV. 201. ‘Punctum’ as a noun corresponds to ἂτομος, for a point has no dimensions; St. August. Ep. 205, 14, ‘atomo temporis, inquit, hoc est in puncto temporis quod diuidi non potest.’ ‘Inquit’ refers to St. Paul I. Ad Corinth. XV. 52, where the N.T. has ν τόμѡ and the present Vulgate ‘in momento.’ And in Ep. 190, 15, St. Austin says ‘summa celeritate atque atomo temporis’; and St. Jerome, Ep. 119, 2, ‘in atomo et in puncto temporis atque momento,’ 5 ‘atomus… punctum temporis est’; J. Cassian, Inst. II. 7, 2, ‘puncto breuissimo’; Lact. Inst. VII. 12 ‘uno temporis puncto.’ ‘Punctum temporis’ or ‘atomus temporis’ means an instant of time that cannot be divided.
