Molossus of Epirus: The Molossus of Epirus (Greek: Μολοσσός της Ηπείρου) is a large dog breed originating from Greece.  It is a livestock guardian that has been bred since the age of Alexander the Great for protecting livestock from carnivorous mammals including the wolf, European jackal and the brown bear in the mountainous regions of Greece, especially Epirus.  The Molossus is a pure Greek breed and is believed to be one of the main ancestors of today's Molosser breeds, such as the English Mastiff and the Neapolitan Mastiff,

Mastinaro: A mastinaro (plural "mastinari") is a Neapolitan Mastiff breeder.  Specifically, "mastinari" are the group of Neapolitan men who have worked since World War II to work as breeders at great personal sacrifice

Dutch barn: Dutch barn is the name given to markedly different types of barns in the United States and Canada, and in the United Kingdom.  In the United States, Dutch barns (a. k. a. New World Dutch barns) represent the oldest and rarest types of barns.  There are relatively few—probably fewer than 600—of these barns still intact.  Common features of these barns include a core structure composed of a steep gabled roof, supported by purlin plates and anchor beam posts, the floor and stone piers below.  Little of the weight is supported by the curtain wall, which could be removed without affecting the stability of the structure.  Large beams of pine or oak bridge the center aisle for animals to provide room for threshing.  Entry was through paired doors on the gable ends with a pent roof over them, and smaller animal doors at the corners of the same elevations.  The Dutch Barn has a square profile, unlike the more rectangular English or German barns.  In the United Kingdom a structure called a Dutch barn is a relatively recent agricultural development meant specifically for hay and straw storage; most examples were built from the 19th century.  British Dutch barns represent a type of pole barn in common use today.  Design styles range from fixed roof to adjustable roof; some Dutch barns have honeycombed brick walls, which provide ventilation and are decorative as well.  Still other British Dutch barns may be found with no walls at all, much like American pole barns.

Neapolitan piastra: The piastra was the most common silver coin of the mainland Kingdom of Sicily, also known as the Kingdom of Naples.  In order to distinguish it from the piastra issued on the island of Sicily, it is referred to as the "Neapolitan piastra" as opposed to the "Sicilian piastra".  These two piastra were equal but were subdivided differently.  The Neapolitan piastra was divided into 120 "grana" (singular: "grano"), each of 2 "tornesi" (singular: "tornese") or 12 "cavalli" (singular: "cavallo").  There were also the "carlino" worth 10 grana and the "ducato" worth 100 grana.

Neapolitan Mastiff: The Neapolitan Mastiff or Mastino (Italian: "Mastino Napoletano" ) is a large, ancient dog breed.  This massive breed is often used as a guard and defender of family and property due to their protective instincts and their fearsome appearance.

Dutch Smoushond: The Dutch Smoushond ("Hollandse Smoushond", "Dutch Ratter") is a small breed of dog, descended from a type of terrier-like dog kept in stables to eliminate rats and mice in Germany and the Netherlands.  They are considered to be related to the Schnauzer.  It is very rare and not well-known outside the Netherlands, its country of origin.

New Haven-style pizza: New Haven-style pizza, locally known as apizza ( , from Neapolitan "’a pizza" (] ) "the pizza"), is a style of Neapolitan pizza common in and around New Haven, Connecticut.  It originated at the Frank Pepe Pizzeria Napoletana and is now served in many other pizza restaurants in the area, most notably Sally's Apizza and Modern Apizza.  This geographically limited pizza style has been favorably referenced by national critics.

Cane da presa: The Cane da Presa Meridionale (Italian for "Southern Catching Dog") is the old, "functional" working variant of the Neapolitan Mastiff.  Before 1946 there was no distinction between Neapolitan Mastiff, Cane da Presa and Cane Corso, these were simply three different names for the same dog.  The modern Neapolitan Mastiff is unlike the original, a dog created by dog shows. Fans of the original Mastino have started an organisation which is trying to gather the remaining specimens which would fit the 1946 standard of the Neapolitan Mastiff.

Griffon: Griffon is a type of dog - a collection of breeds that were originally hunting dogs.  There are three lines of the griffon type recognized by the Fédération Cynologique Internationale (FCI): the griffon vendéens, the wirehaired pointers, and the "smousje" (Belgian companion dogs or Dutch Smoushond).  The griffon type is characterized by rough or wire-hair.
