All the nations of antiquity lived in fixed forms, and their political communities were always organized, down to the lowest ranks. When cities rise into nations, we always find at first a division into tribes. Herodotus mentions such tribes when Cyrene was colonized, and in later times this was also the case at the founding of Thurii; yet when a city any where existed as such, its claim to this character consisted in this, that its citizens were at a certain time divided into communities (γένη), which had a common chapel and the worship of a common hero. In the higher stages of these organizations, the clans were also in certain numerical proportions united into Curies (φράτραι). These clans are not families, but free associations, sometimes close, sometimes open; and in certain cases the general assembly of the state might assign them new members; as in Venice the great council was a close body, and it was so likewise in many of the oligarchical states of antiquity. All the communities had a council and a commonalty, that is to say, a small and a great council, or a council and a popular assembly, the latter of which consisted of the guilds or clans; and these again were united as it were into parishes. The Latin towns have all a council of a hundred persons. This was divided into ten decuries; and these gave rise to the term decurions, which was continued to the latest times for the magistrates of the towns, and also passed by the _lex Julia_ into the constitution of the Italian municipalities. That this council consisted of a hundred persons is shown by Savigny in the first volume of his history of Roman jurisprudence. This constitution survived until late in the middle ages, and was abolished when corporations of the different trades came into the place of the municipal constitution. Giovanni Villani says, that before the revolution in the twelfth century there had been in Florence a hundred _buoni uomini_, who managed the affairs of the town. There is nothing in our German cities corresponding to this constitution. We must not consider these hundred as gentlemen; but they were, as in the small free cities of the empire, an assembly of the burghers and husbandmen, each representing a clan. They are called by Propertius _patres pelliti_. The Curia at Rome, which was thatched with straw (_recens horrebat regia culmo_ in Virgil), was a faithful remembrance of the times when Rome, buried in what may be deemed the night of history, stood like a small country town surrounded by its fields.
