John the Evangelist is one of the twelve apostles of Jesus Christ and is traditionally credited with writing the Gospel of John, three letters (1, 2, and 3 John), and the Book of Revelation in the New Testament. He is often depicted as the beloved disciple and is known for his deep theological insights and emphasis on love and light.
In Christian tradition, John is considered the patron saint of authors, theologians, and publishers. His feast day is celebrated on December 27. John the Evangelist is frequently represented in art with symbols such as an eagle, which signifies the lofty nature of his writings.
