In the decades after Paul Oskar Kristeller’s landmark essay, “The Modern System of the Fine Arts: A Study in the History of Aesthetics” (1951–52), it was common to regard aesthetics as an Enlightenment invention, marked by the appearance of systematic philosophical works such as the Abbé Batteux’s Les Beaux Arts réduits à un même principe (1746) and Baumgarten’s Aesthetica (1750/58), which gave the new discipline its name. Recently, however, that view has been challenged, and the publication of Blackwell’s Companion to Ancient Aesthetics—“the first [volume] of its kind” (5)—signals a departure from Kristellerian orthodoxy. The editors conceive of “ancient aesthetics” broadly, as encompassing “the multifarious ways in which the arts were experienced and conceptualized in the ancient world” (p. 1). The thirty-three chapters that make up the volume are similarly wide-ranging in focus and disciplinary approach, while the insights afforded by their interconnections show the value of treating ancient aesthetics as a unified field of inquiry. Most of the essays would serve as excellent starting points for research on their topics, and several make important new contributions to scholarship. This book is now the most comprehensive resource available for helping us understand how the Greeks and Romans thought about art.
