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 spend a lot of time following two obsessions: packaging and hand lettering. Alongside a few other minor obsessions, those two have been my major ones for so many years now, I've finally reached the point where I can actually claim them as “obsessions” without getting a dramatic reaction from the little voice in the back of my head. When you spend so much time researching and studying a subject, you become very focused, directionally and objectively. But of course some of the research material you run into turns out to be tangential to whatever your focus happens to be at the time, so you absorb what you can from it, then shelf it — like the celebrity bobblehead that amused you for a while, but is now an almost invisible ornament eating dust and feathers somewhere in your environment. And just like the bobblehead may fall off the shelf one day to remind you of its existence, some of my lettering research material unveiled itself in my head one day for no particular reason. Hand lettering is now mostly perceived as an American art. Someone with my historical knowledge about lettering may be snooty enough to go as far as pointing out the British origins of almost everything American, including lettering — but for the most part, the contemporary perspective associates great lettering with America. The same perspective also associates blackletter, gothics and sans serifs with Germany. So you can imagine my simultaneous surprise and impatience when, in my research for one of my American lettering-based fonts, I ran into a German lettering book from 1953, by an artist called Bentele. It was no use for me because it didn't propel my focus at that particular time, but a few months ago I was marveling at what we take for granted — the sky is blue, blackletter is German, lettering is American — and found myself flipping through the pages of that book again. The lettering in that book is upbeat and casual sign making stuff, but it has a slightly strange and youthful experimentation at its heart. I suppose I find it strange because it deviates a lot from the American stuff I'm used to working with for so long now. To make a long story short, what’s inside that German book served as the semilla, which is Spanish for seed, for the typeface you see all over these pages. With Semilla, my normal routine went out the window. My life for a while was all Bezier all the time. No special analog or digital brushes or pens were used in drawing these forms. They're the product of a true Bezier process, all starting with a point creating a curve to another point, which draws a curve to another point, and so on. It’s a very time-consuming process, but at the end I am satisfied that it can get to pretty much the same results easier and more traditional methods accomplish. And as usual with my fonts, the OpenType is plenty and a lot of fun. Experimenting with substitution and automation is still a great pleasure for me. It is the OpenType that always saves me from the seemingly endless work hours every type designer must inevitably have to face at one point in his career. The artful photos used in this booklet are by French photographer and designer Stéphane Giner. He is very deserving of your patronage, so please keep an eye out for his marvelous work. I hope you like Semilla and enjoy using it. I have a feeling that it marks a transition to a more curious and flexible period in my career, but only time will tell.

TT Ricordi useful links: Specimen | Graphic presentation | Customization options The TT Ricordi font family is a collection of three display heading serifs designed to significantly diversify the traditional font palette. Each font from the TT Ricordi family was drawn by a separate designer and has its own story. With that, all three fonts are close in thickness and similar in their character compositions and are featured in the uppercase set and the small capitals set, which replaces lowercase characters. The fonts have the broad support of Latin languages and support basic Cyrillic. The project originates from the pre-coronavirus tourist trips to Italy, during which our art director Yulia Gonina has accumulated many photographs of historical inscriptions and tablets. Many of these inscriptions had interesting character or unusual character shapes. We wanted to work with them, to try to reinterpret them, and, if possible, make them ultramodern and accessible to the modern font user. The fonts from the TT Ricordi typeface turned out to be quite display and contemporary, but at the same time, they retained subtle references to historic inscriptions. The fonts fit perfectly both on the covers of book classics and in glossy magazine layouts. They can also be used in posters and packaging, or as the main expressive element of company branding. In addition, all three serifs from the TT Ricordi font family go well with functional sans-serifs such as TT Norms Pro or TT Commons. TT Ricordi Nobili is a display serif with a rich Roman ancestry and contemporary world views. It stands out from the crowd with its subtlety and elegance. The font was drawn by Anna Tikhonova and was inspired by an inscription carved into the stone floor of a cathedral in Florence. Because people walked over the inscription, some of the letters got thinner and worn out over time. It is this feeling of disappearing or flickering elements that we wanted to capture and implement in the project. The TT Ricordi Nobili has high contrast, even though the font itself is quite thin. The serifs in the font are not massive at all, but at the same time, they are display serifs. There is a certain tension in TT Ricordi Nobili, and the viewer perceives this tension. We can say that behind the external classic facade lies a rather modern plot. The font has a large set of discrete ligatures which allow to create interesting combinations and expand the capabilities of the font. There are 709 glyphs in the TT Ricordi Nobili font, and a whole set of useful features, such as: aalt, ccmp, locl, numr, ordn, tnum, pnum, case, dlig, ss01, ss02, ss06, ss07, ss08, ss09, ss10, calt. TT Ricordi Todi is a wide serif with a classic base and a contemporary nature. The font turned out to be refined yet sharp, and in places even pushy and aggressive. The font was drawn by Yulia Gonina, and the project was based on plaques with engraved street names from the small Italian town of Todi. The main challenge was to decipher the characteristic features of the signs and emphasize them in a modern way. In addition, it was necessary to draw a Cyrillic alphabet that would not be inferior to the Latin alphabet in its expressiveness. The TT Ricordi Todi has fairly wide character proportions, and there is practically no contrast in them. The main feature of the font is the combination of smooth round shapes with deliberately squared shapes. In addition, the font is characterized by crisp and sharp character details, exaggerated ascenders and descenders, and muted contrast. Among the interesting font peculiarities, you can choose between the characteristic long descenders and ascenders and their more tempered versions, you can find a stylistic set with triangular dots, alternative versions of the EF characters and two letter ? shapes, round and squared. There are 876 glyphs in the TT Ricordi Todi font, and a whole set of useful features, such as: aalt, ccmp, locl, numr, ordn, tnum, pnum, case, dlig, salt, ss01, ss02, ss03, ss04, ss05, ss06, ss07, ss08, ss09, ss10, calt. TT Ricordi Fulmini is a fashionable contemporary serif firmly holding on to its historic roots. The font turned out to be like a thistle flower: bright and catchy, but still subtle and delicate. TT Ricordi Fulmini was drawn by Marina Khodak, and the initial inspiration for the project was the inscription on the altar from the National Gallery of Umbria in Perugia. As the font was pulled into “contemporaneity”, it was completely transformed and revealed its new side. The main catchy detail in the TT Ricordi Fulmini is the aggressive and rather sharp diagonal serifs. In addition, in the process of working on the font, several graphic solutions emerged, for example, the mono-serifs and the very calligraphic connections of diagonal strokes with their historic spirit. We wanted to keep them, and thus 4 thematic stylistic sets appeared in the font, thanks to which we can greatly change the perception of TT Ricordi Fulmini. In addition, the font has a set of interesting discrete ligatures. There are 793 glyphs in the TT Ricordi Fulmini font, and a whole set of useful features, such as: aalt, ccmp, locl, numr, ordn, tnum, pnum, case, dlig, ss01, ss02, ss03, ss04, ss05, ss06, ss07, ss08, ss09, ss10, calt.
