Best known for his influential History of Greece, the historian and politician George Grote (1794–1871) wrote this account of Plato's dialogues as a philosophical supplement to the History. First published in 1865 and written in dialogic form, Grote's account of Plato's works includes substantial footnotes and marginalia. This second volume covers the transitional and middle dialogues including Gorgias and Symposium, as well as some of the later works. Grote includes apocryphal works, as he relied on the order and classification of Plato's works specified by the ancient Greek scholar Thrasyllus of Mendes. With three volumes each running to over six hundred pages, Grote's scholarship is formidably comprehensive. The publication of Plato and the Other Companions of Sokrates confirmed him as one of the greatest authorities on Plato in the nineteenth century.
