Second edition of an early treatise claiming to have squared the circle (geometrically constructed a square matching the surface area of a given circle, shown to be impossible in 1882). Falco (Valencia 1522-Madrid 1594), a humanistic poet and mathematician, and a Knight of the Order of Montesa, seems to have been a better poet than mathematician. His treatise has been called "more than commonly worthless" (De Morgan, *A budget of paradoxes*, 1872, p. 36), but it ends with a charming poem. In the first verse, the disappointed squared circle wonders who robbed it of its former noble form, and in the second Falco replies.
