Artichoke production in Italy Artichoke production in Italy Artichoke production in Italy has a long history. Italy is the world's largest producer of artichokes. With Spain and France, the three countries produce more than 80% of the world's artichokes. There are two theories as to its origin: artichokes may have come from the Levant, derived from the cardoon or thistle through a cross-fertilization process, while others attribute it to the work of Italian horticulturists. The first record of artichoke cultivation in Italy was during the fifteenth century in Naples, where it was considered a new food species. In 1466, Filippo Strozzi brought the first
Projective variety Projective variety In algebraic geometry, a projective variety over an algebraically closed field "k" is a subset of some projective "n"-space P over "k" that is the zero-locus of some finite family of homogeneous polynomials of "n" + 1 variables with coefficients in "k", that generate a prime ideal, the defining ideal of the variety. Equivalently, an algebraic variety is projective if it can be embedded as a Zariski closed subvariety of P. A projective variety is a projective curve if its dimension is one; it is a projective surface if its dimension is two; it is a projective hypersurface
