MM', the inflexional asymptote; ABED, the generating circle, 
the center being at C ; B D, a diameter of this circle. 
It was invented by one Diocles, a geometer of the second 
century B. c.. with a view to the solution of the famous 
problem of the duplication of the cube, or the insertion 
of two mean proportion- 
als between two given 
straight lines. Its equa- 
tion is a = 1/2 (a x). In 
the cissoid of Diocles the 
generating curve is a cir- 
cle ; a point A is assumed

then the property of the 
curve is that if from A any oblique line be drawn to MM', 
the segment of this line between the circle and its tangent 
is equal to the segment between A and the cissoid. But 
the name has sometimes been given in later times to all 
curves described in'a similar manner, where the generat- 
ing curve is not a circle.
