This will be my only post for 2021 as I’ve been working on my new book all to do with visualization and imagination in the arts and architecture; through time (almost complete). This post is from my 2020 paper given at Bridges Math/Art 2020. Two animations and one illustration sequence.
The Nazca giant-geoglyph spirals that are etched into the coastal plain desert of southern Peru suggest an easy construction method using a rod and a rope—where the rope is knotted at set path width increments. The rod is pushed into the ground and the rope freely rotated around it—and semi-circular paths are cut at each knot position. The rod is then moved one path width and a new set of semi-circular paths are cut—creating a Nazca spiral. The method can be further developed to create labyrinths—and can be used to create garden, field, sacred, or exhibition labyrinths.
