The Anatomy looks like a crude assembly of quotations and it is indeed a vast mobilization of the notions and expressions of others, yet it is not they but the rifler who is revealed on every page, it is he, not they, who peeps behind every quotation. The reason is clear. He is an artist in literary mosaic, using the shreds and patches he has torn from the work of others to make a picture emphatically his own. Books are his raw material. Other artists fashion images out of clay, contrive fabrics and forms of stone, symphonies of words, sounds or pigments. Burton makes a cosmos out of quotations. He raids the writings of the past, which he often finds neglected or in ruins, and reassembles them in a structure of his own, much as the ruins of Rome were pillaged by the builders of the Renaissance and worked into the temples and palaces of a new civilization.
