The extreme heat waves rolling through Europe have caused an unusually dry summer for Hungary, where the water levels of the Danube River have become drastically low. Archaeologists were hoping to find remnants of the presumed site of the medieval Pentelic Monastery, but instead stumbled upon a piece of an ancient Roman altar dedicated to Jupiter, the chief god of the Roman pantheon. The Discovery Of A Roman Altar Dedicated To Jupiter In The Danube RiverThe find was made by archaeologists from Hungary’s Intercisa Museum during a survey near Szalki Island starting on August 3, taking advantage of the lower water levels of the Danube. Researchers soon found the limestone altar, as well as two pieces of inscribed limestone slabs. Due to potential dangers like this, the Intercisa Museum warned the public against exploring for artifacts themselves in the newly-exposed parts of the Danube.
