Chapter CXI: Act I: SCENE 1. Page 410

ANT. Let Rome in Tiber melt! and the _wide arch_
Of the _rang'd_ empire fall! Here is my space.

As _range_ signifies _compass_, _extent_, so the verb seems to be used, rather licentiously, in the present instance, in the sense of _spread_, _extended_. It may be doubted, at least, whether there be any allusion to a triumphal arch, as Dr. Warburton supposed, or even of a fabric standing on pillars, according to Dr. Johnson. The _wide arch_ may refer to the vast concave of the Roman world, its wide domains covered by _the arch of heaven_, which has been beautifully styled by some oriental writer "the star-built arch of heaven." See _The tales of Inatulla_ by Dow, vol. i. p. 78.

CLEO. O my oblivion is a very Antony
And I am _all_ forgotten.

She compares her memory to Antony, and says she is treacherously abandoned and neglected by _both_. Mr. Steevens's explanation of the first line is satisfactory; but one cannot well agree with him or Mason, that "I am all forgotten" can possibly mean, "I forget myself, or every thing."
