"The Black Prince of Wallachia", tomb no. 10 of Curtea de Argeş
"The Black Prince of Wallachia" nicknamed as such due to the ring he was found wearing being similar to the ring of Edward of Woodstock, the Black Prince. The number 10 tomb was found at the Princely Church of Curtea de Argeş in 1920. It's yet unkown who exactly he is however because of the richly decorated items he was found wearing and the coat of arms appearing on the buttons, he was a Basarab. As of now evidence points to an Alexander, son of Basarab due to the inscription on his ring.
