The three Dialogues of Plutarch entitled:

I. On the E at Delphi,

II. Why the Pythia does not now give her Oracles in Verse,

III. On the cessation of the Oracles,

may be conveniently treated as a group, and assumed to be a collection of those ‘Pythian Dialogues’ which the author sent to his friend Serapion. I and II certainly are so, III has a separate dedication. Other Dialogues, e. g. that on Delays in Divine Punishment, are also records of conversations which took place at Delphi; but these three are concerned with questions suggested by the temple and prophetic office of Apollo, as to which they give much curious information. If they leave us unsatisfied as to matters of still deeper interest, and tell us nothing about the policy of Delphi in the Persian wars, the counsel given to Orestes, which is fiercely controversial matter, or the popular feeling towards the oracle represented in the Ion of Euripides, this is only what we learn to put up with in reading Greek books. Indeed it is of a piece with the purposes imputed to Apollo himself, who sets us problems but does not supply their solution. ‘The king whose oracle is in Delphi neither tells nor conceals, but signifies.’

We have few indications of date, or of mutual relations between the three Dialogues. I is based upon the author’s recollection of a conversation which took place ‘a long time ago’, about A. D. 66, the date of Nero’s visit to Greece. A principal speaker is Ammonius the Peripatetic philosopher of Lamprae, Plutarch’s instructor, who also speaks, with the same authority, in III. In II, Serapion, the Athenian poet, to whom the collection is dedicated in I, takes a leading part. Theon, a literary friend, who appears frequently in the Symposiacs and in the Face in the Moon comes into I and II. An interesting person is Demetrius of Tarsus, another literary friend, who, in III, has just returned from Britain, and who has been probably identified with ‘Demetrius the Scribe’, named on two bronze tablets found at York, and now in the York Museum (see Hermes, vol. 46, p. 156). The year of Callistratus at Delphi, which marks the date of III, is conjecturally fixed as A. D. 83-4 (see Pontow in Philologus for 1895, and cp. Sympos. vii. 5). As Agricola’s term of office ended in A. D. 84 or 85, Demetrius may have served under him. The general tranquillity of the world depicted in III hardly gives us much to build upon.

In I Plutarch and his brother Lamprias are both speakers. Lamprias appears in his usual character, a good companion, light-hearted and reckless; Plutarch speaks gravely and at length, and the debate is closed by Ammonius. In III Lamprias, Plutarch not being named, speaks gravely throughout, and, on the suggestion of Ammonius, closes the debate. In II, neither brother is named, and the last speaker is Theon.

In the Symposiac Dialogues one or other brother is usually present, sometimes both. In the Face in the Moon Lamprias alone takes part, and he acts as moderator.

It is not easy to interpret these facts. M. Gréard concludes that Lamprias died early. If so, was the name, which was borne by the grandfather and by one of the sons, transferred, for literary purposes, to Plutarch himself? M. Chenevière, in his pleasant essay on Plutarch’s friends (a Latin prize dissertation) suggests that, under whatever name, the leading speaker always conveys Plutarch’s own views.

Certain topics recur in this series of Dialogues. Thus the problem as to the meaning of the E at Delphi, which is the main subject of I, is glanced at, with some impatience, by Philippus the historian in III.
