The only collection of all known letters of Christopher Smart provides the best psychological explanation to date of that complex and elusive eighteenth-century poet.

Indeed, it was Smart’s lifelong conviction that he was a poet of major importance. As Smart biographer Karina Williamson notes, "The splendidly informative and vivaciously written accounts of the circumstances surrounding each letter, or group of letters, add up to what is in effect a miniature biography."
