Basket of Fruit (Caravaggio) Basket of Fruit (Caravaggio) Basket of Fruit (c.1599) is a still life painting by the Italian Baroque master Michelangelo Merisi da Caravaggio (1571–1610), which hangs in the Biblioteca Ambrosiana (Ambrosian Library), Milan. It shows a wicker basket perched on the edge of a ledge. The basket contains a selection of summer fruit: ... a good-sized, light-red peach attached to a stem with wormholes in the leaf resembling damage by oriental fruit moth (Orthosia hibisci). Beneath it is a single bicolored apple, shown from a stem perspective with two insect entry holes, probably codling moth, one of which shows secondary rot
Algebraic variety algebraic sets. Using the Nullstellensatz and related results, mathematicians have established a strong correspondence between questions on algebraic sets and questions of ring theory. This correspondence is a defining feature of algebraic geometry. An "affine variety" over an algebraically closed field is conceptually the easiest type of variety to define, which will be done in this section. Next, one can define projective and quasi-projective varieties in a similar way. The most general definition of a variety is obtained by patching together smaller quasi-projective varieties. It is not obvious that one can construct genuinely new examples of varieties in this way,
