Written around 1430, Duarte of Portugal's remarkable treatise on chivalric horsemanship, the Livro do Cavalgar (Book on Riding), is not only the sole substantial contemporary source on the definitive physical skill of the medieval knight, it is a remarkably intelligent and innovative work that still has much to offer to modern practitioners of physical arts. The book stands out from the body of technical writings that survive from the Middle Ages for its intelligence, insight, and intellectual versatility, ranging from psychological reflections on horsemanship and its implications forhuman ethics, to the details of how to couch a lance under your arm without getting it caught on your armor. Under the general rubric of horsemanship Duarte covers a range of topics that include jousting, tourneying, and hunting, as well as the physical apparatus of equestrianism and various cultural styles of riding.
However, despite its importance for scholarship, its language and technicalcontent have so far resisted proper translation, a need which this book fills. The introduction provides not only the background to make Duarte's text comprehensible, but for the first time offers modern audiences a systematic point of access to the subject of medieval equestrianism in general.
