\u201cBlack is your path, Agni, changeless, with glittering waves!\xa0 When like a bull you rush eager to the trees.\nWith teeth of flame, wind-driven, through the wood he speeds, triumphant like a bull among the herd of cows,\nWith bright strength roaming to the everlasting air: things fixed, things moving quake before him as he flies.\u201d-\xa0 Rigvedas, Book 1, Hymn LVIII\n\nDarius retraced Cyrus\u2019s footsteps to expand Persian control of Vedic India.\xa0 Hipparchus met a bloody end at the hands of a jealous rival.\xa0 Tarquin kept Rome\u2019s military and infrastructure sound while alienating both rich and poor.\nLearn more about your ad choices.
