The following is an abstract of Part I. in its present form. Chapters 2, 3, description of the constitution before the time of Draco. 4, Draco's constitution. 5-12, reforms of Solon. 13, party feuds after the legislation of Solon. 14-19, the rule of Peisistratus and his sons. 20, 21, the reforms of Cleisthenes. 22, changes introduced between Cleisthenes and the invasion of Xerxes. 23, 24, the supremacy of the Areopagus, 479-461 B.C. 25, its overthrow by Ephialtes. 26, 27, changes introduced in the time of Pericles. 28, the rise of the demagogues. 29-33, the revolution of the Four Hundred. 34-40, the government of the Thirty. 41, list of the successive changes in the constitution. It may be noted that the reforms of Solon, the tyranny of Peisistratus and his sons, and the revolutions of the Four Hundred and the Thirty, together occupy considerably more than two-thirds of Part I. Part II. describes the constitution as it existed at the period of the composition of the treatise (329-322 B.C.). It begins with an account of the conditions of citizenship and of the training of the _ephebi_ (citizens between the ages of 18 and 20). In chapters 43-49 the functions of the Council ([Greek: boule]) and of the officials who act in concert with it are described. 50-60 deal with the officials who are appointed by lot, of whom the most important are the nine Archons, to whose functions five chapters (55-59) are devoted. The military officers, who come under the head of elective officials, form the subject of c. 61. With c. 63 begins the section on the Law-courts, which occupied the remainder of the _Constitution_. This portion, with the exception of c. 63, is fragmentary in character, owing to the mutilated condition of the fourth roll of the papyrus on which it was written. It will thus be seen that the subjects which receive fullest treatment in Part II. are the Council, the Archons and the Law-courts. The Ecclesia, on the other hand, is dealt with very briefly, in connexion with the _prytaneis_ and _proedri_ (cc. 43, 44).
