It is unclear who is the inventor of sausage, although there is archaeological evidence of its use dating back to 50,000 BC. Humans made the first sausages by stuffing meat from animals they had killed into the emptied and cleaned intestines of the same animals.
The earliest instances of sausage making were an effort to preserve the meat by cutting or mincing it and stuffing it into the intestinal casing. Historically, sausages show up in civilized cultures as early as ancient Greece where most of the sausage consumed was made from pork. There is even a mention of blood sausages in the "Odyssey." Despite consuming it, however, there is no proof the Greeks invented sausage.
