Father's Day, or June 17 of this year, is in the middle of Argentinian winter. And like people do on wintery Sunday mornings, I was bundled up in bed with too many covers, pillows and comforters. Feeling good and not thinking about anything in particular, Father's Day was nowhere in the vicinity of my mind. My eleven year old son, Matías, came into the room with a handmade present for me. Up to this point, my Father's Day gift history was nothing unusual. Books, socks, hand-painted wooden spoons, the kind of thing any father would expect from his pre-teen son. So you can understand when I say I was bracing myself to fake excitement at my son's present. But this Father's Day was special. I didn't have to fake excitement. I was in fact excited beyond my own belief. Matí's handmade present was a complete alphabet drawn on an A4 paper. Grungy, childish, and sweeter than a ton of honey. He'd spent days making it, three-dimensioning the letters, wiggle-shadowing them. Incredible. A common annoyance for graphic designers is explaining to people, even those close to them, what they do for a living. You have to somehow make it understandable that you are a visual communicator, not an artist. Part of the problem is the fact that "graphic designer" and "visual communicator" are just not in the dictionary of standard professions out there. If you're a plumber, you can wrap all the duties of your job with 3.5 words: I'm a plumber. If you're a graphic designer, no wrapper, 3.5 or 300 words, will ever cover it. I've spent many hours throughout the years explaining to my own family and friends what I do for a living, but most of them still come back and ask what it is exactly that I do for dough. When you're a type designer, that problem magnifies itself considerably. When someone asks you what you do for a living, you start looking for the nearest exit, but none of the ones you can find is any good. All the one-line descriptions are vague, and every single one of them queues a long, one-sided conversation that usually ends with someone getting too drunk listening, or too tired of talking. Now imagine being a type designer, with a curious eleven year old son. The kid is curious as to why daddy keeps writing huge letters on the computer screen. Let's go play some ball, dad. As soon as I finish working, son. He looks over my shoulder and sees a big twirly H on the screen. To him it looks like a game, like I'm not working. And I have to explain it to him again. This Father's Day, my son gave me the one present that tells me he finally understands what I do for a living. Perhaps he is even comfortable with it, or curious enough about that he wants to try it out himself. Either way, it was the happiest Father's Day I've ever had, and I'm prouder of my son than of everything else I've done in my life. This is Matí's font. I hope you find it useful.

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.
