Radial design involves elements arranged around or extending out from a central point in a circular or spiral pattern. This type of symmetry and balance can be found in many artworks like Buddhist sand mandalas, Navajo sand paintings, Hawaiian feather capes, rose windows, Mimbres burial bowls, Aztec calendars, the Spiral Jetty land art piece, and the dome of St. Peter's Basilica. Radial design provides unity, harmony, and equal power through similar differences arranged around a center point.
