Piana Apple, Casolana Apple, or Altino Apple
They are tough trees with very scented and medium-size fruits with the characteristic flat-rounded shape, a white and slightly acidulous pulp, aromatic and crunchy. In the past it was a very well-known and widespread variety, already mentioned by the poet Gianbattista Marino (Croce 1925) who, between the 16th and 17th century was guest of the Lords of Conca, owners of the important feudal state of Palena, and by Belli (1930), who talks about "casolana apple". An explicit reference to this apple is also ascribed by some authors to Boccaccio who, in his Friar Puccio's tale, taken from the Decameron, talking about a woman, wrote: "… fresca bella e rotondetta che pareva una mela casolana" (... lusty, comely, and plump like a casolan apple) (Manzi 1999).
