The image of "The Good Shepherd", a beardless youth in pastoral scenes collecting sheep, was the most common of these images, and was probably not understood as a portrait of the historical Jesus. The depiction of Jesus already from the 3rd century included images very similar to what became the traditional image of Jesus, with a longish face and long straight hair. As the Church increased in size and popularity, the need to educate illiterate converts led to the use of pictures which portrayed biblical stories, along with images of saints, angels, prophets, and the Cross (though only portrayed in a bejewelled, glorified state).
