According to Wikipedia: "The Anatomy of Melancholy (Full title: The Anatomy of Melancholy, What it is: With all the Kinds, Causes, Symptomes, Prognostickes, and Several Cures of it. In Three Maine Partitions with their several Sections, Members, and Subsections. Philosophically, Medicinally, Historically, Opened and Cut Up) is a book by Robert Burton, first published in 1621. Burton's book consists mostly of a collection of opinions of a multitude of writers, grouped under quaint and old-fashioned divisions; in a solemn tone Burton endeavoured to prove indisputable facts by weighty quotations. The subjects discussed and determined by Burton ranged from the doctrines of religion to military discipline, from inland navigation to the morality of dancing-schools. On its surface, the book is presented as a medical textbook in which Burton applies his vast and varied learning, in the scholastic manner, to the subject of melancholia (which includes what is now termed clinical depression). Though presented as a medical text, The Anatomy of Melancholy is as much a sui generis work of literature as it is a scientific or philosophical text, and Burton addresses far more than his stated subject. In fact, the Anatomy uses melancholy as the lens through which all human emotion and thought may be scrutinized, and virtually the entire contents of a 17th-century library are marshalled into service of this goal. It is encyclopedic in its range and reference. In his satirical preface to the reader, Burton's persona Democritus Junior explains, "I write of melancholy by being busy to avoid melancholy." This is characteristic of the author's style, which often supersedes the book's strengths as a medical text or historical document as its main source of appeal to admirers. Both satirical and serious in tone, the Anatomy is "vitalized by (Burton's) pervading humour",[3] and Burton's digressive and inclusive style, often verging on a stream of consciousness, consistently informs and animates the text."
