What are the origins of bologna?

Bologna (also known as mortadella) is a type of Italian dry sausage made from pork. The word "bologna" is thought to be derived from the Middle Latin word "botulus," which means "small sausage." Bologna is believed to have originated in the city of Bologna, Italy, in the 13th century. The first written record of bologna is from 1290, when it was mentioned in a document from the city of Bologna. Bologna is made from pork shoulder, pork tripe, and pork fat, and is typically seasoned with garlic, salt, pepper, and spices such as nutmeg, cinnamon, and cloves. Bologna is typically smoked and air-dried, and can be eaten on its own or used as an ingredient in other dishes.
