Nicolai de Cusa Opera Omnia. Venice, 1514. 3 vols. folio.
The real title is "Haec accurata recognitio trium voluminum operum clariss. P. Nicolai Cusae ... proxime sequens pagina monstrat."[44] Cardinal Cusa, who died in 1464, is one of the earliest modern attempters. His quadrature is found in the second volume, and is now quite unreadable.
{48} In these early days every quadrator found a geometrical opponent, who finished him. Regimontanus[45] did this office for the Cardinal.
