conchoidal

Albrecht Dürer born on 21 May 1471 was a German painter, print-maker, mathematician, and theorist. His work on geometry is called the “Four Books on Measurement”. He wrote about linear geometry (Dürer’s geometric constructions include helices, conchoids and epicycloids) and two dimensional geometry (i.e. the construction of regular polygons).

But he is mostly know for the engraving “ Melancolia I” because it was the subject of a lot of interpretations. One of them states that the image explain mathematical knowledge from Durer’s point of view: “Mathematical knowledge is referenced by the use of the symbols: compass, geometrical solid, magic square, scale, hourglass”. The magic square from the image is well-known and also the truncated rhombohedron is now known as Dürer’s solid.
