(2002), Constructing an ellipse in a rosette section, Research Letters in the Information and Mathematical Sciences, 3, 25-351175-2777http://hdl.handle.net/10179/4353Geometry is a craft, an amalgam of science and art. A good development should be pleasing to the mind, kin to poetry. When, after sedentation of a century, a desk was moved in the Laurentian library1, it was discovered that the architect, Michaelangelo, had inscribed an ellipse in a rosette section. Clarifying the nature of this ellipse eluded naive automated algebra. Herein I present a development intended for human appreciation. It is an introduction to the geometry of the rosette diagram. A sketch of the structure of the space of inscribed ellipses. A beginning to a pragmatic description of the meaning and relation between some algebraic equations. A plan of attack on a geometric problem with historical connections. This paper expresses core groundwork I have been conducting in order to embark on the search for a more classical construction of the complete elliptically decorated rosette diagram.enGeometryEllipseArticle
