In 336 B.C. Philip was murdered. Demosthenes set the example of rejoicing by appearing in public crowned with flowers, though he was in mourning for his daughter at the time. The great hopes which the city-states had entertained were dashed to the ground by the energy of Alexander, who, though only twenty years old, proved himself an even greater general and statesman than his father.

Thebes was induced to revolt by Demosthenes, who was supported by Persian gold, but Alexander crushed and destroyed Thebes before help could reach it, and sent an ultimatum to Athens. He demanded the surrender of Demosthenes, Lycurgus, and eight other orators of their party. They were saved, it appears, by the intervention of Demades.[322]

Alexander departed for Asia, and Athenian statesmen were left to quarrel about the politics of their city. It was now that the great case in which Demosthenes and Aeschines were concerned came up for trial. The matter nominally in dispute was only a pretext; it was really a question of reviewing and passing judgment on the political life of the two great antagonists for the last twenty years.

The charges of illegality brought against Ctesiphon were three: (1) That the decree, falsely asserting that Demosthenes had done good service to the State, involved the insertion of a lie into the public records. (2) That it was illegal to crown an official who, like Demosthenes, was still subject to audit. (3) That proclamation of the crowning in the theatre was illegal.

On (2) and (3), the technical points, the prosecutor had a strong case, but the first section was the only one of real importance, since the process was really aimed at Demosthenes. The main part of the speech of Aeschines against Ctesiphon is accordingly devoted to an indictment of the public life of Demosthenes. Four periods are taken: (1) From the war about Amphipolis to the peace of Philocrates (357-346 B.C.). (2) The years of peace (346-340 B.C.). (3) The ministry of Demosthenes (340-338 B.C.). (4) The years after Chaeronea (338-330 B.C.).

The reply of Demosthenes (de Corona) is mainly concerned with a defence of his own policy, the technical points on which the issue nominally depended being kept very much in the background. It is remarkable that in dealing with the early years he makes no attempt to take credit for the great speeches by which in that time he attempted to influence his country—the First Philippic and the three Olynthiacs. He discusses chiefly the peace negotiations. He speaks more fully of the second period, and lays the greatest stress on the third—the years during which he was the acknowledged leader of the people, so that an eulogy of the national policy must involve a tribute to his own patriotism. Only short allusions are made to the last period, the years since the battle of Chaeronea.

The order is not chronological, and the structure is not apparently systematic; nevertheless the de Corona is the greatest of all Athenian speeches.

The speech cannot be represented by extracts; it must be read as a whole to be appreciated. All that a summary can do is to draw attention to the peculiarities of structure, which are possibly due in some measure to the length of the speech and the variety of the subjects which have to be treated:[323]

1. §§ 1-8. The conventional exordium, in this case both introduced and finished by a solemn prayer.

2. §§ 9-52. Refutation of the calumnies uttered by Aeschines. This section consists chiefly of Demosthenes’ own version of the negotiations for the peace of 346 B.C., showing that Aeschines and his associates were really guilty of treason in their dealings with Philip.
