Beautiful as a word or perhaps a name for a fictional character but it's a little too out there for me. In the modern world I feel a child would be bullied with this name. It is unfortunate though because it's quite nice.
Ambrosius Aurelianus was a character of Arthurian legend, said to be the father of Myrdin Emrys (Merlin) and brother of Ûther Pendragon, father to Arthur. He was said to be of completely Roman lineage, and recovered his rightful kingship of Britain from Vortigern, the usurping king.
