The First Part of the Summa in the English Dominican translation (first printed 1911 to 1925; second and revised edition from 1920). A sample check on 2026-11-09 against pre-1931 printings at the Internet Archive (first printings of 1915 and 1916 and the second and revised edition of the 1920s) found that the article text matches, with no 1947 introduction, synopsis, or index.

We next consider all the seven days in common: and there are three points of inquiry:
(1) As to the sufficiency of these days;
(2) Whether they are all one day, or more than one?
(3) As to certain modes of speaking which Scripture uses in narrating the works of the six days.
