Some possibilities, depending on what qualities you want to capture, might be:
* Άρια (Aria): This is a close phonetic approximation and a name used in Greece. It doesn't carry the same meaning, but it's a recognizable and easily pronounceable alternative.
* Αριάδνη (Ariadne): While not a direct translation, this is a classic Greek name with mythological significance (Ariadne helped Theseus escape the Minotaur). It shares a similar sound and is a strong, well-established Greek name.
Ultimately, the "best" translation depends on personal preference. There's no single perfect answer.
