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

The historical lettering style known for its rounded shapes and sharp points is Uncial. This style developed in the 4th to 8th centuries AD, particularly in the context of Latin and Greek manuscripts. Uncial lettering is notable for its broad, rounded characters, which were suitable for the pen used at the time, allowing for a fluid and legible writing style. The sharp points typically come from the way the lettering is formed, with variations in stroke thickness that contribute to an elegant appearance.

In contrast, Celtic lettering is often more intricate and features elaborate knotwork and interlace designs, which do not emphasize the rounded shapes and sharp points seen in Uncial. Gothic lettering is more angular and characterized by pointed arches and a dense structure, resulting in a very different visual style. Roman lettering, while having some rounded elements, is defined by its classic and more structured form, which leans toward straight lines rather than the distinctive rounded shapes of Uncial.

Understanding these nuances helps to clarify why Uncial is the correct choice, as it stands out for its combination of rounded forms and the sharp, pointed ends that define its unique style.
