Note 037
When the ancient texts, which describe the size of Babylon and Thebes, are settled, the exaggerations reduced, and the measures ascertained, we find that those famous cities filled the great but not incredible circumference of about twenty-five or thirty miles. Compare D'Anville, Mem. de l'Academie, tom. xxviii. p. 235, with his Description de l'Egypte, p. 201, 202.
