The problem with which this study is concerned is that of demonstrating the importance of communication and travel in the Siglo de Oro as seen in selected picaresque novels. This study is divided into five chapters. The introductory chapter includes a literary and chronological history of the period and, in the interest of clarity, a plot summary of the selected picaresque novels. The second, third and fourth chapters discuss the various means of urban, rural and maritime communication and travel. The concluding chapter summarizes the study and asserts that communication and travel were of utmost importance during the Siglo LeQ ro and that the picaresque novel, describing faithfully the society that produced it, is a valuable data source for research of this kind.
