Depiction of Jesus in the context of "Shroud of Turin"

Christ Pantocrator of Saint Catherine's Monastery is one of the oldest Byzantine religious icons, dating from the 6th century AD. The earliest known surviving depiction of Jesus Christ as Pantocrator (literally ruler of all), it is regarded by historians and scholars among the most important and recognizable works in the study of Byzantine art as well as Eastern Orthodox and Eastern Catholic Christianity.

In Christian iconography, Christ Pantocrator (Ancient Greek: Χριστὸς Παντοκράτωρ, lit. 'Christ the Almighty') is a specific depiction of Christ. Pantocrator or Pantokrator, literally 'ruler of all', but usually translated as 'almighty' or 'all-powerful', is derived from one of many names of God in Judaism.

The Pantokrator is largely an Eastern Orthodox, Eastern Catholic or Eastern Lutheran theological conception and is less common under that name in Latin Catholicism and Western Lutheranism. In the West, the equivalent image in art is known as Christ in Majesty, which developed a rather different iconography. Christ Pantocrator has come to suggest Christ as a benevolent, though also stern and all-powerful, judge of humanity.

The study of Jesus in comparative mythology is the examination of the narratives of the life of Jesus in the Christian gospels, traditions and theology, as they relate to Christianity and other religions. Although the vast majority of New Testament scholars and historians of the ancient Near East agree that Jesus existed as a historical figure, most secular historians also agree that the gospels contain large quantities of ahistorical legendary details mixed in with historical information about Jesus's life. The Synoptic Gospels of Mark, Matthew, and Luke are heavily shaped by Jewish tradition, with the Gospel of Matthew deliberately portraying Jesus as a "new Moses". Although it is highly unlikely that the authors of the Synoptic Gospels directly based any of their accounts on pagan mythology, it is possible that they may have subtly shaped their accounts of Jesus's healing miracles to resemble familiar Greek stories about miracles associated with Asclepius, the god of healing and medicine. The birth narratives of Matthew and Luke are usually seen by secular historians as legends designed to fulfil expectations about the Messiah.

The Gospel of John bears some influences from Platonism, and may also have been influenced in less obvious ways by the cult of Dionysus, the Greek god of wine, though this possibility is still disputed. Later Christian traditions about Jesus were probably influenced by Greco-Roman religion and mythology. Much of Jesus's traditional iconography is apparently derived from Mediterranean deities such as Hermes, Asclepius, Serapis, and Zeus and his traditional birthdate on 25 December, which was not declared as such until the fifth century, was at one point named a holiday in honour of the Roman sun god Sol Invictus. At around the same time Christianity was expanding in the second and third centuries, the Mithraic Cult was also flourishing. Though the relationship between the two religions is still under dispute, Christian apologists at the time noted similarities between them, which some scholars have taken as evidence of borrowing, but which are more likely a result of shared cultural environment. More general comparisons have also been made between the accounts about Jesus's birth and resurrection and stories of other divine or heroic figures from across the Mediterranean world, including "dying-and-rising gods" such as Tammuz, Adonis, Attis, and Osiris, although the concept of "dying-and-rising gods" itself has received scholarly criticism.

Aniconism is the cultural absence of artistic representations (icons) of the natural and supernatural worlds, or it is the absence of representations of certain figures in religions. The prohibition of material representations may only extend to a specific supreme deity, or it can encompass an entire pantheon, it can also include depictions of a prophet, saints, or sages, or even depictions of living beings and anything in existence generally. It is generally codified by religious traditions and as such, it becomes a taboo. When it is enforced by the physical destruction of images, aniconism becomes iconoclasm.

Aniconism has historical phases in both Buddhism and Christianity, though these movements have been largely rejected as Buddha in art, life of Buddha in art, Buddhas and bodhisattvas in art, God the Father in Western art, Holy Spirit in Christian art, the depiction of Jesus, The Trinity in art, and Manus Dei are common. By contrast Islam has predominantly been aniconistic throughout their histories, including representations of major figures such as Muhammad. The view of aniconism in Judaism has been challenged, with a number of medieval Ashkenazi illuminated manuscripts collected by David Kaufmann. The earliest phases of ancient Greek religion were rich in aniconic representation, even though Greek mythology is heavily anthropomorphic.
