## History

MesoCalc was created in March 2013 by Baptiste Mélès (CNRS, Archives
Henri Poincaré, Université de Lorraine) with the scientific assistance
of Christine Proust (CNRS, Université Paris-Diderot) in the framework of
the SAW Project (Mathematical Sciences in the Ancient World), headed by
Karine Chemla (CNRS, Université Paris-Diderot).

MesoCalc includes computations made by Mathieu Ossendrijver
(Humboldt-Universität) and a calendar designed by Bruno Gombert
(Université Paris 1 Panthéon Sorbonne, ARSCAN), with their benevolent
acceptance.
