Igor, exasperated rather than intimidated by this terrible disaster, resolved upon another expedition, that he might recover his lost renown by inflicting the most terrible vengeance upon the Greeks. He spent two years in making preparations for the enterprise; called to his aid warriors from the most distant tribes of the empire, and purchased the alliance of the Petchenegues. With an immense array of barges, which for leagues covered the surface of the Dnieper, and with an immense squadron of cavalry following along the banks, he commenced the descent of the river. The emperor was informed that the whole river was filled with barges, descending for the siege and sack of Constantinople. In terror he sent embassadors to Igor to endeavor to avert the storm. The imperial embassadors met the flotilla near the mouth of the Dnieper, and offered, in the name of the emperor, to pay the same tribute to Igor which had been paid to Oleg, and even to increase that tribute. At the same time they endeavored to disarm the cupidity of the foe by the most magnificent presents. Igor halted his troops, and collecting his chieftains in counsel, communicated to them the message of the emperor. They replied, "If the emperor will give us the treasure we demand, without our exposing ourselves to the perils of battle, what more can we ask? Who can tell on which side will be the victory?" Thus influenced, Igor consented to a treaty. The opening words of this curious treaty are worthy of being recorded. They were as follows: "We, the embassadors of Igor, solemnly declare that this treaty shall continue so long as the sun shall shine, in defiance of the machinations of that evil spirit who is the enemy of peace and the fomenter of discord. The Russians promise never to break this alliance with the horde; those who have been baptized, under penalty of temporal and eternal punishment from God; others, under the penalty of being for ever deprived of the protection of Peroune;[1] of never being able to protect themselves with their shields; of being doomed to lacerate themselves with their own swords, arrows and other arms, and of being slaves in this world and that which is to come." [Footnote 1: One of the Gods of the Russians.] This important treaty consisted of fourteen articles, drawn up with great precision, and in fact making the Greek emperor as it were but a vassal of the Russian monarch. One of the articles of the treaty is quite illustrative of the times. It reads, "If a Christian kills a Russian, or if a Russian kills a Christian, the friends of the dead have a right to seize the murderer and kill him."
