Historical Background Old South Arabian Script (OSA) was used before the Islamic era not only in the southwest corner of the Arabian Peninsula, but actually in the entire Peninsula. In addition, samples of OSA have been found as far as Uruk in Mesopotamia, Delos in Greece, and Giza in Egypt. Archaeological finds show that as far back as the 8th century BCE, OSA was used in trade, religious writing, and in civil records. Following the spread of Islam in Yemen, the decline of OSA began in the 7th century CE as it was gradually supplanted by Arabic script. OSA was typically known by the name of the then-dominant peoples in the Southern Peninsula. At various times, it was known as Sabaean, Qatabani, or Hadramite, among others. Although it was used for a variety of languages, OSA is most strongly associated with Sabaean. Many Peninsular languages borrowed OSA before introducing further changes of their own. Prime examples are the Thamudic, Safaitic, and Lihyanite scripts which eventually developed into independent scripts. The westward migration of the Sabaean people into the Horn of Africa introduced the South Arabian consonantal alphabet into the region. The transplanted script formed the roots of the Geez script of Ethiopia, which, in time and under presumably external influences, developed into a rich syllabary unlike any other Semitic script in history. Even a cursory examination of the letter forms of Modern Ethiopic writing reveal a striking similarity to South Arabian Script. OSA inscriptions typically reveal a dominant right-to-left directionality, although there are also many cases of alternating directions, known as boustrophedon writing. Figure 1 is a fine example of this style of writing. OSA inscriptions were discovered early in the 19th century. Soon thereafter, two orientalists, Gesenius and Rödiger, made great strides towards deciphering the script. Styles of Writing Old South Arabian inscriptions have survived primarily on stone, ceramic, and metallic surfaces. Hundreds of artifacts have been found and, to this day, continue to be discovered. Some of the best examples number of inscriptions on softer materials, such as wood and leather, have also been discovered. Although there is a significant difference between the styles of letters on the hard surfaces and those on the soft. Old South Arabian (Musnad) is composed of 29 letters , that is one letter more than the Arabic alphabet, which is between “S” and “Sh”, and names “Samekh”. Aspects of difference between Musnad and the present Arabic writing is that Musnad is written in separate letters, and the shape of the letters do not change according to its place in the word. However, some letters change according to the beginning of the writing. Musnad is either prominent, or deep. Prominent writings are for important writings and deep writings are for ordinary. The material on which the Musnad was written were stones, rocks, wood, and metal. In the course of its development the Musnad use appeared in the “Lehyanite’, “Thamudic”, “Safaitic”, pen to which many changes and amendments were made. And from it “Habashi’ writing was born. As regards his place among the Arabs of the Peninsula , when we look at the internet and its role in cultural dialogue , the Arabs of the Peninsula considered Musnad inscription which was indisputably their national writing until the dawn of Islam. It was used by people in all parts of Arabia in their homeland and abroad . It was their means of chronology and record of their glories and history.2- Features of Musnad Script: 1. It is written from right to left and vice versa. 2. Its letters are not joined. 3. Shape of letters are uniform despite their positions in the word. 4. Words are separated by vertical lines. 5. A letter is doubled in case of assertion. 6. No points and punctuations. 7. Easy to be learned by beginners. My OSA Musnad Font My design and technical work is only a treatment of the OSA Musnad as a symbol of writing. And it is possible to use in computer.. My design is not aimed at demonstrating the linguistic and intellectual structure of the Old South Arabian (Musnad). It is so simple that it could be easy to learn by learners and those who are interested in the OSA Musnad letters in computer. The basis of such importance is that it spares a lot of time and effort for researchers and students in this field. Formerly they used to write the Musnad texts either by handwriting or scan them , But now they can easily write its texts in OSA Musnad by using keyboard directly, so that they can change , amend and fulfill easily and accurately . So, we made use of speed, easiness and accuracy. And anyone interested in the South Arabian history in any part of the world can due to this design read and write OSA Musnad letters most easily. This design will also be used by historians and archeologists. , as well as specialist linguistics . The design also demonstrates the aesthetics of the Himyarit writing. About this font family Old South Arabian is An Arabic, Old South Arabian and Latin typeface for desktop applications ,for websites, and for digital ads. Old South Arabian font family contains two types: Old South Arabian and Old South Arabian serif. The font includes a design that supports Arabic, Old South Arabian and Latin languages. Old South Arabian typeface comes with many opentype features.

The idea of a brand-new grotesk is certainly rather foolish – there are already lots of these typefaces in the world and, quite simply, nothing is more beautiful than the original Gill. The sans-serif chapter of typography is now closed by hundreds of technically perfect imitations of Syntax and Frutiger, which are, however, for the most part based on the cool din-aesthetics. The only chance, when looking for inspiration, is to go very far... A grotesk does not afford such a variety as a serif typeface, it is dull and can soon tire the eye. This is why books are not set in sans serif faces. A grotesk is, however, always welcome for expressing different degrees of emphasis, for headings, marginal notes, captions, registers, in short for any service accompaniment of a book, including its titlings. We also often come across a text in which we want to distinguish the individual speaking or writing persons by the use of different typefaces. The condition is that such grotesk should blend in perfectly with the proportions, colour and above all with the expression of the basic, serif typeface. In the area of non-fiction typography, what we appreciate in sans-serif typefaces is that they are clamorous in inscriptions and economic in the setting. John Sans is to be a modest servant and at the same time an original loudspeaker; it wishes to inhabit libraries of educated persons and to shout from billboards. A year ago we completed the transcription of the typefaces of John Baskerville, whose heritage still stands out vividly in our memory. Baskerville cleverly incorporated certain constructional elements in the design of the individual letters of his typeface. These elements include above all the alternation of softand sharp stroke endings. The frequency of these endings in the text and their rhythm produce a balanced impression. The anchoring of the letters on the surface varies and they do not look monotonous when they are read. We attempted to use these tricks also in the creation of a sans-serif typeface. Except that, if we wished to create a genuine “Baroque grotesk”, all the decorativeness of the original would have to be repeated, which would result in a parody. On the contrary, to achieve a mere contrast with the soft Baskerville it is sufficient to choose any other hard grotesk and not to take a great deal of time over designing a new one. Between these two extremes, we chose a path starting with the construction of an almost monolinear skeleton, to which the elements of Baskerville were carefully attached. After many tests of the text, however, some of the flourishes had to be removed again. Anything that is superfluous or ornamental is against the substance of a grotesk typeface. The monolinear character can be impinged upon in those places where any consistency would become a burden. The fine shading and softening is for the benefit of both legibility and aesthetics. The more marked incisions of all crotches are a characteristic feature of this typeface, especially in the bold designs. The colour of the Text, Medium and Bold designs is commensurate with their serif counterparts. The White and X-Black designs already exceed the framework of book graphics and are suitable for use in advertisements and magazines. The original concept of the italics copying faithfully Baskerville’s morphology turned out to be a blind alley. This design would restrict the independent use of the grotesk typeface. We, therefore, began to model the new italics only after the completion of the upright designs. The features which these new italics and Baskerville have in common are the angle of the slope and the softened sloped strokes of the lower case letters. There are also certain reminiscences in the details (K, k). More complicated are the signs & and @, in the case of which regard is paid to distinguishing, in the design, the upright, sloped @ small caps forms. The one-storey lower-case g and the absence of a descender in the lower-case f contributes to the open and simple expression of the design. Also the inclusion of non-aligning figures in the basic designs and of aligning figures in small caps serves the purpose of harmonization of the sans-serif families with the serif families. Non-aligning figures link up better with lower-case letters in the text. If John Sans looks like many other modern typefaces, it is just as well. It certainly is not to the detriment of a Latin typeface as a means of communication, if different typographers in different places of the world arrive in different ways at a similar result.
