Roman square capitals
Roman square capitals, also called capitalis monumentalis, inscriptional capitals, elegant capitals and capitalis quadrata, are an ancient Roman form of writing, and the basis for modern capital letters. Square capitals were used to write inscriptions, and less often to supplement everyday handwriting. When written in documents this style is known as Latin book hand. For everyday writing the Romans used a current cursive hand known as Latin cursive. Notable examples of square capitals used for inscriptions are found on the Roman Pantheon, Trajan's Column, and the Arch of Titus, all in Rome. Square capitals are characterized  by sharp, straight lines, supple curves, thick and thin strokes, angled stressing and incised serifs. These Roman capitals are also called majuscules, as a counterpart to minuscule letters such as Merovingian and Carolingian. Before the 4th century CE, square capitals were used to write "de luxe" copies of the works of authors categorized as "pagan" by Christians, especially those of Virgil; the only three surviving manuscripts using this letter, among them the Vergilius Augusteus, contain works by Virgil. After the 5th century the square capitals fell out of use, except as a display lettering for titles and chapter headings in  conjunction with various script hands for body text: for example, uncials. Square capitals were greatly respected by artisans of the Renaissance such as Geoffroy Tory and Felice Feliciano. A few centuries later, they were also a major inspiration for artisans of the Arts and Crafts movement such as Edward Johnston and Eric Gill, and so many signs and engravings created with an intentionally artistic design in the twentieth century are based on them. Edward Catich is noted for the fullest development of the thesis that the inscribed Roman square capitals owed their form, including the serifs, wholly to the use  of the flat brush, rather than to the exigencies of the chisel or other stone cutting tools. Although not universally accepted, the brushed-origin thesis had been proposed in the nineteenth century. Catich made a complete study and proposed a convincing "ductus" by which the forms were created, using a flat brush and then chisel. He promulgated his views in two works, "Letters Redrawn from the Trajan Inscription in Rome" and "The Origin of the Serif: Brush Writing and Roman Letters". During the early era of the movable type printing press, Roman square capitals became the primary inspiration for the  capital letters in early serif typefaces; Roman type, especially that developed by those associated with Aldus Manutius, came to produce a number of typefaces still used to the present day. The 1989 digital typeface Trajan from Adobe is a direct, all-capital adaptation of the Roman square capitals on Trajan's column.
