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

After my son was born, I found myself reading him a lot of books. A LOT of books. Some were good, some were great, but I found myself wanting to develop something using my skills and interests to make something that only I could make. In short, I realized my son needed to be indoctrinated—I mean, introduced into the wonderfully wild world of fonts. So, I set about to make a board book to teach about typography, called “The Clothes Letters Wear.” You can learn more about the book here. I’ve made the captivating illustrations bright and colorful, and the use of different letter forms makes for a fascinating read to delight ages young and young at heart. And, as an added bonus, this children’s book has a custom designed font. I’m always looking for an excuse to design a new font, and this book created the perfect alibi. Drum roll, please. I now give you … Cabrito (“little goat” en Español). This new serif typeface incorporates the latest research on typographic legibility for children, features to make it—well, extra legible. A little background: studies show that Bookman Old Style is one of the most readable typefaces, and as a consequence or perhaps the reason why, it is used thoroughly for children’s books. This font became my initial inspiration for the typeface. Then, I found more legibility research saying that (brace yourselves) Comic Sans is also very legible for beginning readers, much due to the large x-height and softer, easily recognizable forms. In addition, forms that are closer to handwriting also seem to be more legible. Once I threw all that into my cauldron and stewed it a bit, the result was a pleasantly rounded typeface that includes not-so-strictly geometric, handwriting-inspired forms for the b, d, p, and q. Es guapo! Cabrito’s slender weights are simple and fun, with extras that turn any “bah humbug” into a smile. Add lighter touches to your project with the typeface’s included sparkles or rainbows (not included). Splash a little more color on the page with the firmer look of the thicker weights. Cabrito’s upright variations across all weights are matched by optically altered italics, too, giving you even more variety with the font family. This modern typeface’s bundle of alternates can be accessed in any OpenType-enabled software. The fashionable options involve a significant team of alternates, swashes, and meticulously refined aspects with ball terminals and alternate titling caps to decorate the font. Also bundled are swash alternates, old style figures, and small caps. Peruse the PDF brochure to check out these options in motion. OpenType-enabled applications like the Adobe suite or Quark allows comprehensive control of ligatures and alternates. This font family also provides the glyphs to aid a variety of languages. Cabrito is a welcoming, everyday font family by Jeremy Dooley. Use it to convey warmth and friendliness on anything from candy and food packages to children’s toys, company IDs or run-of-the-mill promotional material. Cabrito’s unique appearance and high legibility make it equally at home in print as it is on a screen.
