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

Out of a lifelong inner struggle, Philip Bouwsma unleashes a masterpiece that reconciles classic calligraphy with type in a way never before attempted. Maestro takes its cue from the Italian chancery cursive of the early sixteenth century. By this time type ruled the publishing world, but official court documents were still presented in calligraphy, in a new formal style of the high Renaissance that was integrated with Roman letters and matched the refined order of type. The copybooks of Arrighi and others, printed from engraved wood blocks, spread the Italian cancellaresca across Europe, but the medium was too clumsy and the size too small to show what was really happening in the stroke. Arrighi and others also made metal fonts that pushed type in the direction of calligraphy, but again the medium did not support the superb artistry of these masters or sustain the vitality in their work. As the elegant sensitive moving stroke of the broad pen was reduced to a static outline, the human quality, the variety and the excitement of a living act were lost. Because the high level of skill could not be reproduced, the broad pen was largely replaced by the pointed tool. The modern italic handwriting revival is based on a simplified model and does not approach the level of this formal calligraphy with its relationship to the Roman forms. Maestro is the font that Arrighi and his colleagues would have made if they had had digital technology. Like the calligraphic system of the papal chancery on which it is modelled, it was not drawn as a single finished alphabet, but evolved from a confluence of script and Roman; the script is formalized by the Roman to stand proudly in a world of type. Maestro came together on screen over the course of several years, through many versions ranging widely in style, formality, width, slant, weight and other parameters. On one end of the spectrum, looking back to tradition it embodies the formal harmony of the Roman capitals and the minuscule which became the lower case. On the other it is a flowing script letter drawing on the spirit of later pointed pen and engravers scripts. As its original designers intended, it works with simple Roman capitals and serifs or swash capitals and baroque flourishes. The broad pen supplies weight and substance to the stroke which carries energy through tension in balanced s-curves. Above all it is meant to convey the life and motion of formal calligraphy as a worthy counterbalance to the stolid gravity of metal type. The Maestro family consists of forty fonts distributed over two weights. The OpenType version compresses the family considerably down to two fonts, regular and bold, each containing the entire character set of twenty fonts, for a total of more than 3350 characters per font. These include a wide variety of stylistic alternates, ligatures, beginning and ending letters, flourishes, borders, rules, and other extras. The Pro version also includes extended linguistic support for Latin-based scripts (Western, Central and Eastern European, Baltic, Turkish, Welsh/Celtic, Maltese) as well as Greek.
