the Sclavonians

At the time, they were living in present-day Russia:

“As their supreme God, they adored an invisible master of the thunder. The rivers and the nymphs obtained their subordinate honours, and the popular worship was expressed in vows and sacrifice. The Sclavonians disdained to obey a despot, a prince, or even a magistrate; but their experience was too narrow, their passions too headstrong, to compose a system of equal law or general defence. Some voluntary respect was yielded to age or valour; but each tribe or village existed as a separate republic, and all must be persuaded where none could be compelled. They fought on foot, almost naked, and, except an unwieldy shield, without any defensive armour; their weapons of offence were a bow, a quiver of small poisoned arrows, and a long rope, which they dexterously threw from a distance, and entangled their enemy in a running noose. In the field, the Sclavonian infantry was dangerous by their speed, agility, and hardiness; they swam, they dived, they remained under water, drawing their breath through a hollow cane; and a river or lake was often the scene of their unsuspected ambuscade. But these were the achievements of spies or stragglers; the military art was unknown to the Sclavonians; their name was obscure, and their conquests were inglorious.”
