Medieval literature is rich with subjects of agricultural association derived from biblical texts, early church documentary accounts, and regional folklore. St. John the Baptist has been venerated at various times of the year as Herald of the Harvest, and since the Middle Ages on Midsummer Day—June 24, in part because of the metaphorical significance of his prophetic call for repentance before the baptism of Jesus: “His winnowing fork is in His hand, and He will thoroughly clear His threshing floor; and He will gather His wheat into the barn, but He will burn up the chaff with unquenchable fire” (Matthew 3:12). The holy days of the medieval harvest season reaffirmed the cycle of the Jewish agrarian calendar although these commemorations typically took place three to four months later with the cooler climates and later harvests of northern Europe.
The patron saint of harvesters and peasants, St. Isidore the Farmer (c. 1070-1130), was curiously honored less because of his agricultural diligence than his attention to prayer and worship even when interrupting field operations on his master’s estate in Spain. But St. Isidore, who is often portrayed in paintings and sculpture with a sickle fastened beneath his belt, remained steadfast in religious observations and his crops flourished. His wife, St. Maria Torriba (d. 1175), was also canonized for the miraculous provision of grain after she shared their few precious seeds with the needy and foraging birds.
