Are we trying to figure out the clue? I've come to the conclusion that there were as many as five Dionysiuses. The third one was the son of some Kabir, known in Thrace as Sabazius.
Another option is to focus on the "aspects" of Dionysus. But that doesn't quite fit: based on the description of the clue, it would logically suggest a resilient bull, and the bull is considered the first aspect, not the third.
