From her time in Slovenia, Devra Bogdanovich  might recall the legend of the capital city of Ljubljana and its dragon: 

Legend has it that Ljubljana was founded by the Greek mythological hero Jason and his companions, the Argonauts, who had stolen the golden fleece from King Aetes and fled from him across the Black Sea and up the Danube, Sava and Ljubljanica rivers.

They stopped at a large lake in the marsh near the source of the Ljubljanica, where they disassembled their ship to be able to carry it to the Adriatic Sea, put it together again, and return to Greece. The lake where they made a stop was the dwelling place of a monster. Jason fought the monster, defeated it and killed it. The monster, now referred to as the Ljubljana Dragon, found its place atop the castle tower on the Ljubljana coat of arms.
