So too in the Italian and German cities of the Middle Ages, the patrician families refused to part with their own separate political identity, when the guilds grew up by the side of them; even though forced to renounce a portion of their power, they continued to be a separate fraternity, and would not submit to be regimented anew, under an altered category and denomination, along with the traders who had grown into wealth and importance. But the reform of Clisthenes effected this change all at once, both as to the name and as to the reality. In some cases, indeed, that which had been the name of a gens was retained as the name of a deme, but even then the old gentiles were ranked indiscriminately among the remaining demots; and the Athenian people, politically considered, thus became one homogeneous whole, distributed for convenience into parts, numerically, locally, and politically equal. It is, however, to be remembered, that while the four Ionic tribes were abolished, the gentes and phratries which compose them were left untouched, and continued to subsist as family and religious associations, though carrying with them no political privilege.
The ten newly created tribes, arranged in an established order of precedence, were called: Erechtheis, Ægeis, Pandionis, Leontis, Acamantis, Œneis, Cecropis, Hippothoöntis, Æantis, Antiochis—names borrowed chiefly from the respected heroes of Attic legend. This number remained unaltered until the year 305 B.C., when it was increased to twelve by the addition of two new tribes, Antigonias and Demetrias, afterwards designated anew by the names of Ptolemais and Attalis. The mere names of these last two, borrowed from living kings and not from legendary heroes, betray the change from freedom to subservience at Athens. Each tribe comprised a certain number of demes—cantons, parishes, or townships—in Attica. But the total number of these demes is not distinctly ascertained.
There is another point, however, which is at once more certain, and more important to notice. The demes which Clisthenes assigned to each tribe were in no case all adjacent to each other; and therefore, the tribe, as a whole, did not correspond with any continuous portion of the territory, nor could it have any peculiar local interest, separate from the entire community. Such systematic avoidance of the factions arising out of neighbourhood will appear to have been more especially necessary, when we recollect that the quarrels of the Paralii, the Diacrii, the Pedieis, during the preceding century, had all been generated from local feud, though doubtless artfully fomented by individual ambition. Moreover, it was only by this same precaution that the local predominance of the city, and the formation of a city-interest distinct from that of the country, was obviated; which could hardly have failed to arise had the city by itself constituted either one deme or one tribe. Clisthenes distributed the city (or found it already distributed) into several demes, and those demes among several tribes; while Piræus and Phalerum, each constituting a separate deme, were also assigned to different tribes; so that there were no local advantages either to bestow predominance, or to create a struggle for predominance, of one tribe over the rest. Each deme had its own local interests to watch over; but the tribe was a mere aggregate of demes for political, military, and religious purposes, with no separate hopes or fears apart from the whole state. Each tribe had a chapel, sacred rites and festivals, and a common fund for such meetings, in honour of its eponymous hero, administered by members of its own choice; and the statues of all the ten eponymous heroes, fraternal patrons of the democracy, were planted in the most conspicuous part of the agora of Athens. In the future working of the Athenian government we shall trace no symptom of disquieting local factions—a capital amendment compared with the disputes of the preceding century, and traceable, in part, to the absence of border-relations between demes of the same tribe.
