Lower yet, beneath the Agora, the town of common men covered the lower hill-side in such order or disorder as its steepness allowed.

Here was no conventional town-planning.

Only a yet lower and later city, built in Roman days on more or less level spaces beside the stream Selinus, seems perhaps to have been laid out in chess-board fashion.[39] The Attalid kings, the founders of Pergamon, cared only for splendid buildings splendidly adorned.

If their abrupt hill-side forbade the straight and broad processional avenues of some other Greek cities, they crowned their summits instead with a crescent of temples and palaces which had not its like on the shores of the Aegean.

Yet even Pergamon had its building-laws and by-laws for the protection of common life.
