The two kings of Sparta.
It was a peculiarity in the constitution of Sparta that, from a very early period of its history, there had been always two kings, who had each other, like the Roman consuls in later times. This custom was sustained partly by the idea that by this division of the executive power of the state, the exercise of the power was less likely to become despotic or tyrannical. It had its origin, however, according to the ancient legends, in the following singular occurrences:
Origin of the custom of two kings.
The twins.
At a very early period in the history of Sparta, when the people had always been accustomed, like other states, to have one prince or chieftain, a certain prince died, leaving his wife, whose name was Argia, and two infant children, as his survivors. The children were twins, and the father had died almost immediately after they were born. Now the office of king was in a certain sense hereditary, and yet not absolutely so; for the people were accustomed to assemble on the death of the king, and determine who should be his successor, choosing always, however, the oldest son of the former monarch, unless there was some very extraordinary and imperious reason for not doing so. In this case they decided, as usual, that the oldest son should be king.
But here a very serious difficulty arose, which was, to determine which of the twins was the oldest son. They resembled each other so closely that no stranger could distinguish one from the other at all. The mother said that she could not distinguish them, and that she did not know which was the first-born. This was not strictly true; for she did, in fact, know, and only denied her power to decide the question because she wished to have both of her children kings.
The Delphic oracle consulted.
In this perplexity the Spartans sent to the oracle at Delphi to know what they were to do. The oracle gave, as usual, an ambiguous and unsatisfactory response. It directed the people to make both the children kings, but to render the highest honors to the first-born. When this answer was reported at Sparta, it only increased the difficulty; for how were they to render peculiar honors to the first-born unless they could ascertain which the first-born was?
Plan for ascertaining the eldest.
In this dilemma, some person suggested to the magistrates that perhaps Argia really knew which was the eldest child, and that if so, by watching her, to see whether she washed and fed one, uniformly, before the other, or gave it precedence in any other way, by which her latent maternal instinct or partiality might appear, the question might possibly be determined. This plan was accordingly adopted. The magistrates contrived means to place a servant maid in the house to watch the mother in the way proposed, and the result was that the true order of birth was revealed. From that time forward, while they were both considered as princes, the one now supposed to be the first-born took precedence of the other.
