River Rhine, Germany. The name of the Rhine in most languages comes from Celtic 'Renos', literally "that which flows", from the Proto-Indo-European root *rei- ("to flow, run"), which also gave the word "to run" in English. http://en.wikipedia.org/wiki/Rhine

Rune stones are standing stones with runic inscriptions dating from the Iron Age (Viking Age) and early Middle Ages. The Runic alphabets are a set of related alphabets using letters known as runes, formerly used to write Germanic languages, mainly in Scandinavia and the British Isles. In all their varieties they may be considered an ancient writing system of Northern Europe. See http://en.wikipedia.org/wiki/Runic_alphabet and http://en.wikipedia.org/wiki/Runestone
