Fifteen in a row So in this second story there were only three rows of pillars, which were sufficient for the ornament of the second and for the support of the third story; and we may conjecture from hence that there were threescore pillars below. Light was against light One directly opposite to another, as is usual in well-contrived buildings. In three ranks One exactly under another in three rows. All the doors, &c., were square with the windows That is, the figures of the doors and windows were one and the same, namely, square. And light was against light, &c. This is meant of the smaller windows or lights which were over the door, and which were also square.
