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.
With the direction line (containing the quire signature and/or catchword) shaved on 4 pages, but still in very good condition, binding fine. An ill-fated attempt to solve an impossible problem, here by someone who thought he had succeeded.
