Histories

There are seven circles in all; within the innermost circle are the palace and the treasuries; and the longest wall is about the length of the wall that surrounds the city of Athens [23.7333,37.9667] (Perseus)Athens.[*](About eight miles, according to a scholiast's note on Thucyd. ii. 13; but this is disputed.) The battlements of the first circle are white, of the second black, of the third circle purple, of the fourth blue, and of the fifth orange:

thus the battlements of five circles are painted with colors; and the battlements of the last two circles are coated, the one with silver and the other with gold.
