Again, Medea caused the daughters of Pelias to put to death their aged father by deluding them into the belief that by cutting him in pieces and boiling him with certain magic potions, they would restore him to youth and vigour.[258] Here Medea acts as the ‘plotter and contriver’[259] of murder. In primitive as in historical[260] times, such a deed was regarded as equally culpable with that of an actual slayer—indeed, in the special circumstances of the case she was the real if not the actual murderer of Pelias, and the daughters of Pelias were guilty, at most, of involuntary slaying. We cannot of course attribute to Medea the guilt of kin-slaying, as she was not akin to Pelias. It is more probable that she would have been regarded, for purposes of punishment, as an ordinary murderess. In actual fact, she and Jason were expelled from Thessaly. Even so, in the play,[261] she still fears the vengeance of Acastus, the son of Pelias. This fact does not imply that she was conceived as guilty of kin-slaying, which in historical Greece was punishable by death. We believe that the Thessalian story of Medea was not conceived from the standpoint of historical law.
In this story there are complications of blood-vengeance which suggest an Achaean, or rather what we may call a quasi-Achaean atmosphere. While, in Homer,[262] Pelias, son of Poseidon, rules over Iolcos like an Achaean, by divine right, later legend revealed that he had previously defrauded his half-brother Aeson of the kingdom and put him to death, and that Jason the son of Aeson had himself narrowly escaped death at his hands. Hence it was natural that Jason, the one-sandalled hero of the oracle,[263] should command Medea to put Pelias to death. That is the real reason why Jason, together with Medea, was banished from Thessaly by Acastus. This quasi-Achaean exile is therefore similar to the Achaean ‘flight from death,’ and hence it is that Medea still fears the vengeance of Acastus.[264] When Jason arrived at Corinth, he became affianced to the king’s daughter, just as the Achaean Tydeus became the son-in-law of Adrastus.[265] No pollution was involved in an alliance with a kin-slayer! The presence of such Achaean episodes in Euripides, side by side with episodes which bear a later stamp, suggests either a marvellous capacity for archaising on the part of the dramatist or, more probably, the unadulterated transmission of an antique legend.[266]
The main plot of this drama reveals two further atrocities which were perpetrated by Medea. She plots the death of her husband, of his intended wife, Glauce, of his intended father-in-law, Kreon, King of Corinth, and of her own two children, whom she had borne to Jason. Her murderous plot proved successful, except in regard to Jason. Her children she slew deliberately with her own hand. It happened, previously, that Aegeus, King of Athens, arrived at Corinth. Medea, well aware of the consequences of the murderous plot which she had planned, and being, in addition, under an edict of banishment from Corinth, entreated Aegeus to give her protection at Athens.[267] He promised to do so, but she was not content with a promise. She bound Aegeus under a solemn oath:
Swear by the earth on which we tread, the sun,
Thy grandsire and by all the race of gods ...
That from your land you never will expel,
Nor while you live consent that any foe
Shall tear me thence.[268]
One or two problems are suggested by this quotation. If Medea had not succeeded in securing this solemn contract on the part of Aegeus, would she have carried out her plot? And was Aegeus bound by the oath when he discovered the sequel? In this section of the story—which is the main theme of our play—homicide is conceived as a ‘pollution,’[269] and in the pollution system exile was not permitted for voluntary kin-slaying.[270] The murder of her children was by far the most serious offence which Medea committed, since they were her kindred. For the other deeds of blood she could have legally sought asylum at Athens, as she was not a citizen of that State, and the deeds had not been perpetrated there. Medea seems to be well aware of these facts, for she utters no hint to Aegeus of her dreadful plans. But it was her intention of slaying her children which led her to extract from Aegeus this solemn oath. If he had refused to swear, she would, we believe, have slain all her intended victims, but she would then have committed suicide.
But was the oath which Aegeus swore binding in Greek international law? Apparently Medea thought so, and Euripides seems to think so, too. The Chorus, however, do not understand how Medea can find a refuge at Athens. But it is only in the slaying of the children that they seem to find a difficulty. They say[271]:
