The “loxodromic”curve and the herringbone

Abstract

In hemisphere domes the development of the spirals of the herringbone creates a “loxodromic” curve. The curve of the herringbone comes closer and closer to the poles of the sphere. A structure with an octagonal base, presents greater difficulties in the application of this technique; its structure does not have the same continuity as the round dome; as observed previously, each "vela" is a portion of an elliptical cylinder, and not a sphere.
