Didonia (plural Didonias)

  1. (geometry) The curve which on a given surface and with a given perimeter contains the greatest area.
    • 1867, Peter Guthrie Tait, An Elementary Treatise on Quaternions:
      And hence, by Meusnier's theorem, the difference of the squares of the curvatures of curve and surface is constant; the curvature of the surface meaning here the reciprocal of the radius of the sphere which osculates in the reduction of the element of the Didonia.
