As in ancient Rome in its earlier history, and as in all other early urban communities, agriculture necessarily played a considerable part in the life of most mediæval towns. Like the villages they possessed each its own mark, with its common fields, pastures, and woods. These were demarcated by various landmarks, crosses, holy images, etc.; and "the bounds" were beaten every year. The wealthier citizens usually possessed gardens and orchards within the town walls, while each inhabitant had his share in the communal holding without. The use of this latter was regulated by the Rath or Council. In fact, the town life of the Middle Ages was not by any means so sharply differentiated from rural life as is implied in our modern idea of a town. Even in the larger commercial towns, such as Frankfurt, Nürnberg or Augsburg, it was common to keep cows, pigs, and sheep, and, as a matter of course, fowls and geese, in large numbers within the precincts of the town itself. In Frankfurt in 1481 the pigsties in the town had become such a nuisance that the Rath had to forbid them _in the front_ of the houses by a formal decree. In Ulm there was a regulation of the bakers' guild to the effect that no single member should keep more than twenty-four pigs, and that cows should be confined to their stalls at night. In Nürnberg in 1475 again, the Rath had to interfere with the intolerable nuisance of pigs and other farmyard stock running about loose in the streets. Even in a town like München we are informed that agriculture formed one of the staple occupations of the inhabitants, while in almost every city the gardeners' or the winegrowers' guild appears as one of the largest and most influential.
