Book excerpt: The Book of the Courtier, Baldassare Castiglione's classic account of Renaissance court life, offers profound insight into the refined behavior which defined the era's ruling class. The courtly customs and manners of Italy to a great extent characterized the Renaissance, which elevated art and expression to new heights. Baldassare Castiglione published this book with the intention of chronicling the manners, customs and traditions which underpinned how courtiers, nobles, and their servants, behaved. Although ostensibly a book of etiquette and good conduct, Castiglione's treatise carries enormous historical value. He derived his observations directly from the many gatherings and receptions conducted by society's elite. Conversations with the officials, diplomats and nobility of the era further enhanced the accuracy of this book, imbuing it with an authenticity seldom seen elsewhere.
