black letter script at English => English (The Britannica Concise) Of Explained:
Style of alphabet used in handwriting throughout Europe in the Middle Ages. It features uniform, vertical strokes that end on the baseline, angular lines instead of smooth curves and circles, and the overlapping of convex forms. Black letter and roman were the dominant letter shapes of medieval typography. The only extant work by J. Gutenberg, the 42-line Bible (1450s), was set in black letter type. Roman type largely superseded it in the Renaissance, though it persisted in Germany well into the 20th cent. Today black letter is often used for diplomas, Christmas cards, and liturgical writings.
