HIRRI a people mentioned by Pliny (Plin. Nat. 4.13) along with the Venedae, and who were connected with the Heruli. They appear to have come from Scandinavia, and occupied that part of the coast of Esthonia, which was called in the Middle Ages Harria, after them. Thus, it seems that the coasts of the Baltic, as far as the mouth of the Oder, were exposed to the piratical attacks of the Goths, in very early times, as in later ages other European shores were devastated by the Normans.
