III. The HELOTS were serfs bound to the soil, which they tilled for the benefit of the Spartan proprietors. Their condition was very different from that of the ordinary slaves in antiquity, and more similar to the villanage of the middle ages. They lived in the rural villages, as the Perioeci did in the towns, cultivating the lands and paying over the rent to their masters in Sparta, but enjoying their homes, wives, and families, apart from their master's personal superintendence. They appear to have been never sold, and they accompanied the Spartans to the field as light armed troops. But while their condition was in these respects superior to that of the ordinary slaves in other parts of Greece, it was embittered by the fact that they were not strangers like the latter, but were of the same race and spoke the same language as their masters, being probably the descendants of the old inhabitants, who had offered the most obstinate resistance to the Dorians, and had therefore been reduced to slavery. As their numbers increased, they became objects of suspicion to their masters, and were subjected to the most wanton and oppressive cruelty. The functions of the Spartan government were distributed among two kings, a senate of thirty members, a popular assembly, and an executive directory of five men called the Ephors. At the head of the state were the two hereditary kings. The existence of a pair of kings was peculiar to Sparta, and is said to have arisen from the accidental circumstance of Aristodemus having left twin sons, Eurysthenes and Procles. This division of the royal power naturally tended to weaken its influence and to produce jealousies and dissensions between the two kings. The royal power was on the decline during the whole historical period, and the authority of the kings was gradually usurped by the Ephors, who at length obtained the entire control of the government, and reduced the kings to a state of humiliation and dependence. The Senate, called GERUSIA, or the COUNCIL OF ELDERS, consisted of thirty members, among whom the two kings were included. They were obliged to be upwards of sixty years of age, and they held their office for life. They possessed considerable power and were the only real check upon the authority of the Ephors. They discussed and prepared all measures which were to be brought before the popular assembly, and they had some share in the general administration of the state. But the most important of their functions was, that they were judges in all criminal cases affecting the life of a Spartan citizen. The Popular Assembly was of little importance, and appears to have been usually summoned only as a matter of form for the election of certain magistrates, for passing laws, and for determining upon peace and war. It would appear that open discussion was not allowed and that the assembly rarely came to a division.
