quadrata

The term "quadrata" refers to square capitals, an early form of the Latin alphabet. These capital letters were characterized by their elegant and clear formation, with slightly heavier downstrokes and lighter upstrokes, and the use of serifs. They were primarily seen in imperial Roman stone inscriptions and set a high standard for the Roman alphabet's appearance. Unlike rustic capitals, which were more flowing and used for books, square capitals were more formal and often created with a chisel, mimicking brush strokes. Both square and rustic capitals largely disappeared by the late 7th century AD.123
