Gilded belt buckles discovered across Europe have revealed a previously-unknown ancient fertility cult with ties across the continent, researchers believe.

Four bronze belt ends depicting a snake devouring a frog—thought to be a symbol of creation and/or fertility—were recently discovered in Moravia, Bohemia, Bavaria, and Hungary. Because of their near-identical shape and make, archaeologists now believe that these belt ends are evidence of an unknown pagan cult with far-reaching and diverse populations across Europe in the early Middle Ages.
