Mathematician and putti; Title page for: Gregory à Sancto Vincentio, Problema Austriacum Plus Ultra Quadratura Circuli, 1647. A lion skin is tense with the title of the book between two columns. A man signs a circle and a triangle in the sand with a stick. Two men look behind him. Right two putti that show medals, behind three putti that draw a circle with a passer.
