Object Details
- Baker, Richard P.
- Description
- This painted plaster model showing contour lines fits in an open wooden box.
- In a catalog from about 1905, Baker described the surface shown as “An area which can be derived by deformation from 92 [e.g. model MA.211257.014] without losing the descriptive character of contours, except that the inloop curve becomes an outloop (which may occur in infinitesimal transformation). The contours are now curves of the type of equipotential lines, and the configuration is made as symmetrical as possible.”
