Calligraphic refers to the brushstrokes and lines in Cy Twombly's paintings that resemble calligraphy. These elements are often gestural, energetic, and expressive, contributing to the abstract nature and emotional depth of his works. Twombly's use of writing and text, inspired by ancient Roman graffiti, further emphasizes the calligraphic quality of his visual language, blending art and literature in unique ways.
