Frederick Apthorp Paley and John Malcolm Mitchell, 1911 Encyclopædia Britannica (1911)
“ In the life of Aratus, not Sosius Senecio, but one Polycrates, is addressed. The Lives are works of great learning and research, long lists of authorities are given, and they must for this very reason, as well as from their considerable length, have taken many years in compilation. It is true that many of the lives, especially of Romans, do not show such an extent of research. But Plutarch must have had access to a great store of books, and his diligence as an historian cannot be questioned, if his accuracy is in some points impeached. ”
