The story Saint Martin's goose
The tradition of eating goose on the day dedicated to Saint Martin is rooted in a centuries-old history. Along with the pig, the goose constituted the main reservoir of fats and proteins for rural communities, whose winter diet otherwise relied almost exclusively on cereals and polenta.
The bond between humans and geese spans across the greatest ancient civilizations. Starting from Egyptians to Omero, the goose was considered an excellent custodian, as exemplified by the famous geese of the Temple of Juno on the Campidoglio.
Among many ancient populations, this waterfowl was a sacred symbol linked to the afterlife, regarded as a pilgrim’s guide, and revered as the Great Mother of the Universe. Centuries later, the goose’s foot was used as a distinctive mark of recognition by the master builders of Gothic cathedrals, who called themselves “Jars” (the French word for ganders).
During medieval times, goose breeding continued to prosper in monasteries and feuds, supported by the decrees of Charlemagne. A turning point for the spread of this consumption in Northern Italy occurred around 1400 with the arrival of Ashkenazi Jewish communities from Northern Europe. Unable to consume pork meat for religious reasons, Jewish butchers specialised in processing goose, creating salamis and hams that remained a favourite food among wealthy families until the end of the nineteenth century.
Already rooted in Celtic tradition, November 11th entered the Christian calendar precisely thanks to Saint Martin and has always been associated with geese. Legend has it that despite being elected Bishop of Tours by popular acclaim, Martin did not wish to abandon his monastic habit and attempted to hide; however, it was the geese that flushed him out, leading to his appointment as a beloved bishop and, eventually, a Saint known for his profound kindness toward the poor.
Furthermore, during the last century and up until the early 1900s, the goose also served as a medium of exchange. Tenant farmers and sharecroppers used the animals to pay noble landowners part of their dues, or they would head to the market to trade geese for boots.
