EIRĒN or ĪRĒN (εἴρην or ἴρην), the name given to the Spartan youth when he attained the age of twenty. At the age of eighteen he emerged from childhood, and was called μελλείρην. When he had attained his twentieth year, he began to exercise a direct influence over his juniors, and was entrusted with the command of troops in battle. The word appears to have originally signified a commander. The ἰρένες mentioned in Herodotus, in connection with the battle of Plataeae, were certainly not youths, but commanders. EISANGĔLĬA (εἰσαγγελία), signifies, in its primary and most general sense, a denunciation of any kind, but, much more usually, an information laid before the council or the assembly of the people, and the consequent impeachment and trial of state criminals at Athens under novel or extraordinary circumstances. Among these were the occasions upon which manifest crimes were alleged to have been committed, and yet of such a nature as the existing laws had failed to anticipate, or at least describe specifically (ἄγραφα ἀδικήματα), the result of which omission would have been, but for the enactment by which the accusations in question might be preferred (νόμος εἰσαγγελτικός), that a prosecutor would not have known to what magistrate to apply; that a magistrate, if applied to, could not with safety have accepted the indictment or brought it into court; and that, in short, there would have been a total failure of justice. EISITĒRĬA (εἰσιτήρια, _scil._ ἱερά), sacrifices offered at Athens by the senate before the session began, in honour of the Θεοὶ Βουλαῖοι, _i.e._ Zeus and Athena.
