From the standpoint of calligraphy, a font family of capitals and uncials makes perfect sense. The Roman square capitals, the quadrata, are matched by round capitals of older Greek origin; the word "uncus" means hook-shaped like a beak or talon. Interrelated and often interchangeable, these capital letters served as book hands for both the Latin West and the Greek-speaking East before they evolved into minuscule alphabets. The Testament family is based on the few formal capital manuscripts of the Bible, Virgil and Homer that have survived from the ancient world. Throughout the Middle Ages both uncials and square capitals were used, often together, for headings and initial characters. By their nature the Roman capitals are the voice of Caesar and hold the place of authority, while the uncials speak for the Church in a balanced relationship. In ancient times church and state were not as separate as they are now, and the alphabets were not as different as typographic tradition has made them. In this calligraphic rendering it is clear that they are of the same substance and can be written in the same style, conveying even to the modern eye the eternal and classical quality of epic and scripture. Testament comes in all popular font formats, and includes support for a vaster-than-usual range of Latin-based languages.
