Core
The word sun comes from the Old English word sunne, which itself comes from the older Proto-Germanic language’s word sunnōn. During the reign of the Roman Empire, Helios was replaced with the Latin name Sol. Like Helios, Sol is a term that is still used to describe the Sun.
Sol is the Roman equivalent of the Greek sun god Helios. And maybe in earlier times English-speakers did use these names. According to straightdope.com, the first cited use of Sol as a proper name for the sun is the 1450 Ashmole Manuscript Treatise on Astrology, which stated: Sol is hote & dry but not as mars is.
