Divina Proportione is based from the original studies from Luca Pacioli. Luca Pacioli was born in 1446 or 1447 in Sansepolcro (Tuscany) where he received an abbaco education. Luca Pacioli was born in 1446 or 1447 in Sansepolcro (Tuscany) where he received an abbaco education. [This was education in the vernacular (i.e. the local tongue) rather than Latin and focused on the knowledge required of merchants.] He moved to Venice around 1464 where he continued his own education while working as a tutor to the three sons of a merchant. It was during this period that he wrote his first book -- a treatise on arithmetic for the three boys he was tutoring. Between 1472 and 1475, he became a Franciscan friar. In 1475, he started teaching in Perugia and wrote a comprehensive abbaco textbook in the vernacular for his students during 1477 and 1478. It is thought that he then started teaching university mathematics (rather than abbaco) and he did so in a number of Italian universities, including Perugia, holding the first chair in mathematics in two of them. He also continued to work as a private abbaco tutor of mathematics and was, in fact, instructed to stop teaching at this level in Sansepolcro in 1491. In 1494, his first book to be printed, Summa de arithmetica, geometria, proportioni et proportionalita, was published in Venice. In 1497, he accepted an invitation from Lodovico Sforza ("Il Moro") to work in Milan. There he met, collaborated with, lived with, and taught mathematics to Leonardo da Vinci. In 1499, Pacioli and Leonardo were forced to flee Milan when Louis XII of France seized the city and drove their patron out. Their paths appear to have finally separated around 1506. Pacioli died aged 70 in 1517, most likely in Sansepolcro where it is thought he had spent much of his final years. De divina proportione (written in Milan in 1496–98, published in Venice in 1509). Two versions of the original manuscript are extant, one in the Biblioteca Ambrosiana in Milan, the other in the Bibliothèque Publique et Universitaire in Geneva. The subject was mathematical and artistic proportion, especially the mathematics of the golden ratio and its application in architecture. Leonardo da Vinci drew the illustrations of the regular solids in De divina proportione while he lived with and took mathematics lessons from Pacioli. Leonardo's drawings are probably the first illustrations of skeletonic solids, an easy distinction between front and back. The work also discusses the use of perspective by painters such as Piero della Francesca, Melozzo da Forlì, and Marco Palmezzano. As a side note, the "M" logo used by the Metropolitan Museum of Art in New York City is taken from De divina proportione. “ The Ancients, having taken into consideration the rigorous construction of the human body, elaborated all their works, as especially their holy temples, according to these proportions; for they found here the two principal figures without which no project is possible: the perfection of the circle, the principle of all regular bodies, and the equilateral square. ” —De divina proportione

I love geometric sans serifs, their crispness and rationality. Le Havre taps into this style, but for a while, I've wanted to create a font recalling the printed Futura of the 1940s, which seems to have an elusive quality all its own. After seeing an old manual on a World War II ship, I developed a plan for "Le Havre Metal" but chose to shelve the project due to Le Havre's small x-height. That's where Steagal comes in. When Robbie de Villiers and I began the Chatype project in early 2012 (a project which led one publication to label me the Edward Johnston of Chattanooga!), we started closely studying the vernacular lettering of Chattanooga. During that time, I also visited Switzerland, where I saw how designers were using a new, handmade aesthetic with a geometric base. I was motivated to make a new face combining some of these same influences. The primary inspiration for the new design came from the hand-lettering of sign painters in the United States, circa 1930s through 1950s. My Chatype research turned up a poster from the Tennessee Valley Authority in Chattanooga, Tennessee, which exhibited a number of quirks from the unique hand and style of one of these sign artists. Completing the first draft of Steagal, however, I found that the face appeared somewhat European in character. I turned then to the work of Morris Fuller Benton for a distinctly American take and discovered a number of features that would help define Steagal as a "1930s American" vernacular typeface--features I later learned also inspired Morris Fuller Benton's Eagle. The overall development of Steagal was surprisingly difficult, knowing when to deliberately distort optical artifacts and when to keep them in place. Part of type design is correcting optical illusions, and I found myself absentmindedly adjusting the optical effects. In the end, though, I was able to draw inspiration from period signs, inscriptions, period posters, and architecture while retaining just enough of the naive sensibility. Steagal has softened edges, which simulate brush strokes and retain the feeling of the human hand. The standard version has unique quirks that are not too intrusive. Overshoots have almost been eliminated, and joins have minimal corrections. The rounded forms are mathematically perfect, geometric figures without optical corrections. As a variation to the standard, the “Rough” version stands as the "bad signpainter" version with plenty of character. Steagal Regular comes in five weights and is packed with OpenType features. Steagal includes three Art Deco Alternate sets, optically compensated rounded forms, a monospaced variant, and numerous other features. In all, there are over 200 alternate characters. To see these features in action, please see the informative .pdf brochure. OpenType capable applications such as Quark or the Adobe Creative suite can take full advantage of the automatically replacing ligatures and alternates. Steagal also includes support for all Western European languages. Steagal is a great way to subtly draw attention to your work. Its unique quirks grab the eye with a authority that few typefaces possess. Embrace its vernacular, hand-brushed look, and see what this geometric sans serif can do for you.
