Widely acknowledged as the most authoritative study of ancient Greece, George Grote's twelve-volume work, begun in 1846, established the shape of Greek history which still prevails in textbooks and popular accounts of the ancient world today. Grote employs direct and clear language to take the reader from the earliest times of legendary Greece to the death of Alexander and his generation, drawing upon epic poetry and legend, and examining the growth and decline of the Athenian democracy. The work provides explanations of Greek political constitutions and philosophy, and interwoven throughout are the important but outlying adventures of the Sicilian and Italian Greeks. Volume 4 continues the review of Greek contacts in the wider Mediterranean world, and also covers political developments, especially in Athens, from the rise of the Peisistratids to the battle of Marathon.
