Beyond the ancient model of the 'Paradise Garden' in both Christian and Islamic tradition, the other often-cited early precedents for today's gardens are the monastery and castle gardens of the Late Middle Ages. We haven't had a chance to visit many of these, but here are two examples.
Together, the early example of The Alhambra in the Islamic tradition, the monasteries of the Middle Ages, and the early castle gardens provide the foundation for more modern gardening traditions. Next week we'll jump ahead to the Renaissance and the formal gardens of Italy and France.
Correction - as John pointed out in the comments below, Katherine Parr was not the only Queen to outlive Henry VIII. I have corrected the text above, and here are the facts. Though the story of Henry having Anne Boleyn beheaded has coloured our view, only she and Catherine Howard were in fact beheaded. Catherine of Aragon lived on for 3 years after being set aside for Anne Boleyn, as Dowager Princess of Wales, Jane Seymour died of complications in childbirth (but did give Henry his only son, Edward, who survived), and his marriage to Anne of Cleeves was annulled. She in fact lived longer than any of the wives, outliving Henry by 10 years.
