Geometrical distributions of vessels thrown.

<p>The geometrical space is formed by the first two principal components of the PCA performed on the coefficients of the elliptical Fourier analysis of the vessel outlines. Blue open markers represent all vessels thrown by the French potters; green open markers represent all vessels thrown by the Indian Multani potters. Using the same colour code, the 95%-confidence ellipses are superimposed, with their principal axes and centroids (solid markers). The solid black markers represent the model shape. Panel A: Small 0.75 kg spheres. Panel B: Large 2.25 kg spheres.
