Which historical lettering style is characterized by rounded shapes and sharp points?

The historical lettering style characterized by rounded shapes and sharp points is indeed the Celtic style. This style features intricate lettering that often includes loops, spirals, and angular forms which contribute to its unique aesthetic. The blending of rounded shapes with pointed finishes gives Celtic scripts a distinctive look that is both decorative and functional, effectively capturing the artistic spirit typical of early medieval manuscript illumination.

Celtic lettering is often seen in the context of early Irish and British written art, particularly in historical texts and religious manuscripts. The style reflects the cultural heritage and artistic traditions of the Celtic people, making it stand out from other historical lettering forms.

Other styles mentioned, such as Gothic, Roman, and Uncial, each have their own unique characteristics, but they don't embody the specific combination of rounded shapes and sharp points that define the Celtic style. Gothic lettering tends to be more angular and intricate without the pronounced rounded elements, Roman letters are typically more classical and uniform, and Uncial is known for its more rounded and even letters, but without the sharp points found in Celtic.
