Calvizzano is located in the fertile plain south of the Regi Lagni, in the heart of the Campania plain, in a highly urbanized area. The municipality is located in the agglomeration northwest of Naples (the Giuglianese countryside) together with the municipalities of Marano, Mugnano, Villaricca, Qualiano and Giugliano in Campania.
According to the local historian Raffaele Galiero the name derives fromCalvisius (or Calvicius), a landowner belonging to the gensCalvisia. From here the name which would have transformed intoCalvisiano,Calbictian and finallyCalvizzano.
In the seventeenth century the notary Marco Antonio Syrleto, the first local historian, had formulated another etymological hypothesis for the toponym: according to him this would have derived from the fact that in ancient times, following the many wars and plagues, in this place many tombs containing only skulls were found, which were calledcalvi ; when healthy people came to this territory to live there, from the union of theCalvi to thesani, the nameCalvisano would have been born, later translated by the common people intoCarvizzano and then intoCalvizzano.[3]
