| | Cissoid of Diocles |
 | | When informed of the oracle's admonition, Plato told the citizens "the god has given this oracle, not because he wanted an altar of double the size, but because he wished in setting this task before them, to reproach the Greeks for their neglect of mathematics and their contempt of geometry." |
 | | The curve invented by Diocles in about 180 BC later appears in the works of Fermat, Roberval, Huygens, Wallis, Newton, and others. |
 | | Problems on the cissoid's curvature, arc length, and areas bounded by its asymptote are found in modern calculus texts. |
