Jesus Christus is latin for Jesus Christ.
The depiction of Jesus in art took several centuries to reach a conventional standardized form for his physical appearance, which has subsequently remained largely stable since that time.
There are many paintings of Jesus. Here is an 11th-century Christ Pantocrator with the halo in a cross form, used throughout the Middle Ages. Characteristically, he is portrayed as similar in features and skin tone to the culture of the artist.
