"Create an image of Saint John the Evangelist in a classical style

"Create an image of Saint John the Evangelist in a classical style, with a serene and contemplative expression. He must be wearing traditional clothes, with a flowing tunic and rich details. In one hand, he holds a feather, symbolizing the writing of the Gospel. on the shoulder, there must be an eagle, representing spiritual vision and higher understanding. The background can be soft and bright, with a spiritual atmosphere that highlights the presence of Saint John and his symbols."
