In Celtic calligraphy, the letter style taught consists of which type of letters?

Celtic calligraphy is traditionally known for its ornate and decorative uppercase letters, often characterized by intricate designs and embellishments. These letters can often be seen in manuscript illuminations and medieval texts, where the upper case serves not only a functional purpose but also an artistic one. The style emphasizes the beauty and complexity of the capitals, which are crafted with great care and skill.

While lowercase letters are certainly important in other forms of calligraphy, the focus in traditional Celtic calligraphy training often rests primarily on the uppercase forms. They serve as the foundation for demonstrating the unique characteristics of the Celtic style, including knotwork and elaborate strokes. Although italics can also be a type of calligraphy, they are not specifically associated with the intricacies of Celtic letterforms, which further supports the preference for uppercase letters in this context.
