Cambyses first observed that the carriage she was on was attached to four stong, strapping horses, all adorned with bright blue and golden clothes.
It seemed this was the 'barding' Alexander was talking about.
Over her sides, she then noticed that a large number of soldiers too had similarly dressed horses which they were mounting, releasing an imposing aura as each of them held a spear and a shield in each hand and carried a crossbow on their back.
These were their escort who would guard them when they passed through the city.
And lastly Cambyses spun her head back to see all the guests get on their own, less flashy carriages, all pulled by two horses.
It went without saying the number of horses attached to a carriage delineated its significance.
And today Alexander and Cambyses were the most significant ones.
