The second part of this publication deals with 1.17-36 in the unpublished fragment (B), which without doubt form the most original part of the law. For it was not only a question of creating an obstacle to a coup d'Etat that that would overturn a genuine democracy (represented by a boule and prytaneia of Athenian type, whose members were chosen by lot among the Eretrians), but also of henceforth reestablishing this constitution if a tyranny or oligarchy--interesting association--was imposed by violence. Each citizen was invited to take up arms spontaneously (this clause offered a remarkable dialectical form, a semi-passive participation of Northwestern origin). An eventuality is envisaged of the People being no longer in control of the civic centre, in particular the zone of the bouleuterion designated there probably by the term Agoraion(=Metroon at Athens!), or even of them being kept outside the town: in this case the democratic elements should regroup in some part of the territory, a tactic well attested in Greece and even Eretria (the role of the maritime fortress of Porthmos) in order to retake the power. Lastly, sanctions are envisaged against citizens who had not served the cause of the People, while its defenders would be rewarded by the grant of lands and goods belonging to those who had been guilty. A considerable concluding section reviews the principal problems posed by this document: the date, circumstances of its promulgation, place(s) it was exhibited, identity of the legislator, and possible juridical and/or philosophical models. Today it seems certain that the law (necessarily before 336) has to be related to the liberation of Eretria in the autumn of 341, a relatively well documented event. As is a priori probable, an influence by Athenian legislation can be detected in the first part of the text. But a comparison with the celebrated law proposed by Eucrates of Piraeus in 337/6 shows that the Attic model would not account for all its particularities. The Eretrian law--which is, moreover, the oldest of its kind to have survived on stone--appears rather to be the fruit of an unhappy political experience undergone in the recent past.
