The two early Slavic alphabets, the Cyrillic and the Glagolitic, were invented by Saints Cyril and Methodius. These men were from Thessalonica, and they traveled to the southern Slavic regions to spread Christianity. An early tradition, in attributing the invention of an early Slavic writing to Cyril, does not indicate whether his contribution was the Cyrillic or the Glagolitic. It is just possible that both alphabets were invented by him. The earliest dated Old Slavic documents belong to the late 10th and the 11th centuries. The Cyrillic and the Glagolitic alphabets differed widely in the form of their letters, in the history of their development, and partly also in the number of the letters, but they were alike in representing adequately the many sounds of Slavic.

The Cyrillic alphabet was based on the Greek uncial writing of the 9th century It originally had a total of 43 letters; the two Hebrew letters tzade and shin were transformed into the Cyrillic letters for the sounds ch, sh, and shch. The modern forms of this alphabet have fewer letters. Glagolitic writing consisted of 40 letters, externally very unlike either the Greek or Cyrillic scripts.

Cyrillic became, with slight modification in each case, the national script of the Bulgarians, Serbs, Montenegrins, Russians, Belarusians, and Ukrainians. (The other Slavic peoples—the Slovenes, Croats, Bosnians, Czechs, Slovaks, Wends, Lusatians, and Poles—use the Latin alphabet.) For a time, Cyrillic was also adapted to the Romanian language, and in recent times, through the medium of Russian script, it became the writing of a number of Finno-Ugric languages (Komi, Udmurt, Mordvinian, Mansi, Khanty, etc.), Turkic languages (Chuvash, Turkmenian, Azerbaijanian, etc.), Iranian languages (Ossetic, Kurdish, Tajik), and Caucasian languages (Abkhaz, Circassian, Avar, etc.).

The history of the Glagolitic alphabet is particularly connected with the religious history of the Slavic peoples of southwest central Europe and the western Balkan Peninsula. In the second half of the 9th century, it was introduced, together with the Slavonic liturgy, into the Moravian kingdom, but with the banning of this liturgy by the pope it disappeared from Moravia. It was, however, accepted (also with the Slavonic liturgy) in Bulgaria and Croatia and spread along the Dalmatian coast southward into Montenegro and westward into Istria. Although the Glagolitic script soon disappeared among the Greek Orthodox Slavic peoples because of the victory of the Cyrillic, it continued, notwithstanding the opposition of the higher Roman Catholic authorities, to be employed among the Roman Catholics of the western Balkan Peninsula together with the Slavonic liturgy and finally succeeded in obtaining the special license of the pope. It is still employed in the Slavonic liturgy in some Dalmatian and Montenegrin communities; the inhabitants of these places are the only Roman Catholics to use the Slavonic liturgy. The earliest preserved Glagolitic secular document dates from 1309. Glagolitic had a short flourishing period in the 16th and 17th centuries.

Etruscan alphabet

The Etruscans, a highly civilized people who were the ancestors of the modern Tuscans and the predecessors of the Romans, inhabited what is now Tuscany in central Italy; their language, still mainly undeciphered, has come down in more than 11,000 inscriptions, the earliest being the 8th-century-bce Marsiliana Tablet, preserved in the Archaeological Museum in Florence. This is also the earliest preserved record of a Western alphabet. The early Etruscan alphabet, unlike any early Greek alphabet found in the Greek inscriptions, contains the original—the prototype—Greek alphabet, consisting of the 22 North Semitic letters, with the phonetic values given to them by the Greeks, and the four additional Greek letters at the end of the alphabet. The Etruscans introduced various changes in their script, and several features in the modern alphabets can be attributed to the influence of the ancient Etruscans. An example is the phonetic value of /k/ for the letters c, k, and q. Like the Semitic and the early Greek alphabets, Etruscan writing nearly always reads from right to left, though a few inscriptions are in boustrophedon style. The probable date of the origin of the Etruscan alphabet is the late 9th or early 8th century bce.

About 400 bce the “classical” Etruscan alphabet took its final form of 20 letters—four vowels and 16 consonants. Because the voiced and voiceless sounds b and p, d and t, g and k were not differentiated in the Etruscan language, the letters b and d never appear in pure Etruscan inscriptions, and after the disappearance of k and q, the letter C was employed for g and k.

The Etruscan alphabet had many varieties and several offshoots. Among the offshoots, apart from the Latin, were many alphabets used by Italic populations of pre-Roman Italy and by non-Italic tribes (e.g., the Piceni).

Latin alphabet

The adaptation of the Etruscan alphabet to the Latin language probably took place some time in the 7th century bce. From this century there is a gold brooch known as the Praeneste Fibula (preserved in the National Museum of Prehistory and Ethnography “Luigi Pigorini” in Rome). The inscription, written in an early form of Latin, runs from right to left and reads clearly: manios: med:fhefhaked:numasioi, which in Classical Latin is Manius me fecit Numerio (“Manius made me for Numerius”).

Dating from the end of the 7th or the beginning of the 6th century bce is a famous cippus (small pillar) from the Roman Forum; it is inscribed vertically on its four faces, in boustrophedon style. Another inscription, probably of the 6th century bce, is known as that of the Duenos Vase and was found in Rome, near the Quirinal Hill. It is also written from right to left. Some Sabine inscriptions belong to the 5th or the 4th century bce. There are also a few inscriptions belonging to the 3rd and 2nd centuries bce.

The Roman capital letters, a form of writing that was used under the empire with unparalleled effectiveness for monumental purposes, became a byword for precision and grandeur, despite a very unprepossessing beginning. Indeed, for the first six centuries of its existence, Roman writing was relatively unimpressive. Only with the advent of the 1st century bce were there signs of magnificence to come.

An opinion that used to be commonly held, and still is held by many, is that the Latin alphabet was derived directly from the Greek in a form used by Greek colonists in Italy. The theory rested on an assertion that the Latin alphabet corresponds to the Chalcidian variety of the western group of Greek scripts employed at Cumae in Campania, southern Italy. This theory is unlikely; indeed, as already mentioned, the Etruscan alphabet was the link between the Greek and the Latin. For instance, the most interesting feature in the inscription of the Praeneste Fibula is the device of combining the letters f and h to represent the Latin sound of f. This was one of the Etruscan ways of representing the same sound. Also, most of the Latin letter names, such as a, be, ce, de for the Greek alpha, beta, gamma, delta, and so on, were taken over from the Etruscans.
