A reader directed me to a wonderful website called "Omniglot, a guide to writing systems", which illustrates examples of various alphabets of the world. By examining some of these we can begin to see the influences which may have led to development of the Germanic/Norse rune alphabets. It is commonly thought that the Etruscan and Latin alphabets were sources, but as you will see below, there may have been others, also. All of the data that follows are from the information and graphics from the Omniglot website.
First, let's look at the major runic alphabets (called "futharks" based upon the first six symbols). There are many other variants, but the Elder, Anglo-Saxon, and Younger Futharks are the most well-known.
Runes were used to write many languages including, Gothic, German, Frisian, English, Danish, Swedish, Norwegian, Icelandic, Lithuanian, Russian, Hebrew and other Semitic languages (due to trade relations with the Khazars, a Semitic tribe of traders of the Silk Road).
The runes might be read from left to right or from right to left, even on the same artifact. Translation of runic inscriptions is therefore extremely difficult, and complicated by the fact that rune masters sometimes wrote cryptic puzzles or in secret script.
"The Elder Futhark is thought to be the oldest version of the runic alphabet, and was used in the parts of Europe which were home to Germanic peoples, including Scandinavia. Other versions probably developed from it. The names of the letters are shown in Common Germanic, the reconstructed ancestor of all Germanic languages."
"A number of extra letters were added to the runic alphabet to write Anglo-Saxon/Old English. Runes were probably bought to Britain in the 5th century by the Angles, Saxons, Jutes and Frisians (collectively known as the Anglo-Saxons), and were used until about the 11th century. Runic inscriptions are mostly found on jewelry, weapons, stones and other objects. Very few examples of runic writing on manuscripts have survived. " [The chart that follows is incomplete. There are additional A-S runes, which you can seehere.]
Younger (or Scandinavian) Futhark
"This version of the runic alphabet was used sporadically in Scandinavia, in particular in Denmark and Sweden, until about the 17th century ." [There are variants of the Younger Futhark also, which you can seehere.]
The commonality of symbols of all of the following alphabets makes sense when one considers the migration of ancient peoples from the east to the west. The people and languages of northern Europe are considered "Indo-European" because of this migration. It's not unreasonable that customs, languages, alphabets, mythology, etc. share common origins. Staggering, isn't it!
"The Etruscan alphabet is thought to have been developed from the Greek alphabet by Greek colonists in Italy. The earliest known inscription dates from the middle of the 6th century BC.
More than 10,000 Etruscan inscriptions have been found on tombstones, vases, statues, mirrors and jewelry. Fragments of a Etruscan book made of linen have also been found.
Most Etruscan inscriptions are written in horizontal lines from left to right, but some are boustrophedon (running alternately left to right then right to left).
Used to write: Etruscan, a language spoken by the Etruscans, who lived in Etruria (Tuscany and Umbria) between about the 8th century BC and the 1st century AD. Little is known about the Etruscans or their language."
"The Old Italic alphabets developed from the west Greek alphabet, which came to Italy via the Greek colonies on Sicily and along the west coast of Italy. The Etruscans adapted the Greek alphabet to write Etruscan sometime during the 6th century BC, or possibly earlier. Most of the other alphabets used in Italy are thought to have derived from the Etruscan alphabet."
