"The many images of tennis from the thirteenth century onwards assisted Gillmeister in tracing the development of the game, for example, when the racquet began to be regularly used, the height and arrangement of the net and even styles of play. He shows its particular hold on the artistic imagination and how it had a special relationship to courtly literature and to a conception of the ideal; human being. It appeared as a recommended part of a young man's education, contributing to a 'civilising process', teaching good manners and appropriate behaviour, as well as providing a suitable form of bodily exercise, so long as it was not taken to excess - although Charles V dismissed it as one of the games that did 'nothing to teach the manly art of bearing arms'. Its appearance in the medieval romance literature added to its glamour and eroticism, for it was associated, long before the Victorian garden party, with dalliance as well as sporting vigour and courage in combat. It was also considered an intellectual game and known as 'chess in motion', so it is easy 'to see why such a game should so have fascinated the intellectuals of the Middle Ages - who were the monks'. Indeed, one writer thought 'the art of the racquet the most appropriate sport for the man of letters'."
