Ares itself is used abstractly by the Greeks for destruction, murder, pestilence, just as our Wuotan is for furor and belli impetus, and the Latin Mars for bellum, exitus pugnae, furor bellicus

we may fairly bring in the Goth. haírus, AS. heor, OS. heru, ON. hiörr sword, ensis, cardo, although the names of the rune and the day of the week always appear without the aspirate. For in Greek we already have the two unaspirated words Ares and Aor, sword, weapon, to compare with one another, and these point to a god of the sword. Then again the famous Abrenuntiatio names three heathen gods, Thunar, Wôden, Saxnôt, of whom the third can have been but little inferior to the other two in power and holiness. Sahsnôt is word for word gladii consors, ensifer [...] I think we may also bring in the Gallic war-god Hesus or Esus (Lucan 1, 440), and state, that the metal iron is indicated by the planetary sign of Mars, the AS. tîres tâcen, and consequently that the rune of Zio and Eor may be the picture of a sword with its handle , or of a spear. The Scythian and Alanic legends dwell still more emphatically on the god's sword, and their agreement with Teutonic ways of thinking may safely be assumed, as Mars was equally prominent in the faith of the Scythians and that of the Goths. The impressive personification of the sword matches well with that of the hammer, and to my thinking each confirms the other. Both idea and name of two of the greatest gods pass over into the instrument by which they display their might."
