A step ahead of him, Suniaton nearly collided with a carpenter carrying several long cypress planks. Rather than apologise, he thumbed his nose and sprinted towards the citadel walls, now only a hundred paces away. Stifling his desire to finish the job by tipping over the angry tradesman, Hanno dodged past too, a grin splitting his face. Another similarity he and Suniaton shared was an impudent nature, quite at odds with the serious manner of most of their countrymen. It frequently got both of them in trouble, and was a constant source of irritation to their fathers.

A moment later, they passed under the immense ramparts, which were thirty paces deep and nearly the same in height. Like the outer defences, the wall was constructed from great quadrilateral blocks of sandstone. Frequent coats of whitewash ensured that the sunlight bounced off the stone, magnifying its size. Topped by a wide walkway and with regular towers, the fortifications were truly awe-inspiring. Yet the citadel was only a small part of the whole. Hanno never tired of looking down on the expanse of the sea wall that came into view as he emerged from under the gateway’s shadow. Running down from the north along the city’s perimeter, it swept southeast to the twin harbours, curling protectively around them before heading west. On the steep northern and eastern sides, and to the south, where the sea gave its added protection, one wall was deemed sufficient, but on the western, landward side of the peninsula, three defences had been constructed: a wide trench backed by an earthen bank, and then a huge rampart. The walls, which were in total over 180 stades in length, also contained sections with two-tiered living quarters. These could hold many thousands of troops, cavalry and their mounts, and hundreds of war elephants.

Home to nearly a quarter of a million people, the city also demanded attention. Directly below lay the Agora, the large open space bordered by government buildings and countless shops.
