People like to believe in a past golden age of `traditional' English countryside, before large farms, machinery, and the destruction of hedgerows changed the landscape forever. However, that countryside may have looked both more and less familiar than we imagine. Take, for example, today's startling yellow fields of rapeseed, seemingly more suited to the landscape of Van Gogh than Constable. They were in fact, thoroughly familiar to fieldworkers in seventeenth-century England. At the same time, some features that would have gone unremarked in the past now seem like oddities. In the fifteenth century, rabbits were reared in specially guarded warrens as luxury food for rich men's tables; whilst houses had moats not only to defence but to provide a source of fresh fish. In the 1500s we find Catherine of Aragon introducing the concept of fresh salad to the court of Henry VIII; and in the 1600s, artichoke gardens became a fashion of the gentry in their hope of producing more male heirs. The common tomato, suspected of being poisonous in 1837, was transformed into a household vegetable by the end of the nineteenth century, thanks to cheaper glass-making methods and the resulting increase in glasshouses. In addition to these fascinating images of past lives, Joan Thirsk reveals how the forces which drive our current interest in alternative forms of agriculture - a glut of mainstream meat and cereal crops; changing patterns of diet; the needs of medicine - have striking parallels with earlier periods of our history. She warns us that today's decisions should not be made in a historical vacuum. We can still find solutions to today's problems in the hard-won experience of people in the past.
