This dance recounts how Ludovic met in 2011 his now wife, Charlotte. They were at that time students in the high school Pierre de Fermat in Toulouse. They flirted for a while but essentially stayed with their own friends, which is why 1st man stays with men and 1st woman stays with women; the 1st couple only briefly touches. It is thanks to their friends that they finally got together on 21 November 2011; this is represented in the dance by the allemande turns of 2nd and 3rd couples, the “cupidos”. The title refers to the place where they met, the name of which comes from a mathematician.
