  1. Thallus

    Thallus, was an early historian who wrote in Koine Greek. Some scholars believe that his work can be interpreted as the earliest reference to the historical Jesus, and argue that it was written about 20 years after the Crucifixion. He wrote a three-volume history of the Mediterranean world from before the Trojan War to the 167th Olympiad, c. 112-109 BC. Most of his work, like the vast majority of ancient literature, perished, but not before parts of his writings were repeated by Sextus Julius Africanus in his History of the World. The works are considered important by Christian scholars because they believe them to help confirm the historicity of Jesus. Some people believe that Thallus details the crucifixion of Jesus but explains that the darkness that fell over the land at the time of Jesus' death was not a miracle as reported in the Canonical gospels, but merely an eclipse. However, this is impossible as only a lunar eclipse can occur at Passover, and lunar eclipses are not visible at mid day due to the moon being directly opposite the sun, and therefore below the horizon. An eclipse can therefore not be used to establish a pre-Markan origin for the story spoken of in the Gospel of Mark as some people claim.
