It is (often) said that participles in Ablative Absolutes in Early Latin have an adjectival nature (e.g., see Ruppel (2013: 124): "the Early Latin Ablative Absolute is not strongly verbal at all"). For some remarks on the verbal vs. adjectival passive distinction in Latin, please see this previous question.
If Ruppel's statement is correct, which I tend to think it is, one consequence that is not pursued by her is that the so-called "ablative of agent" could not appear in this non-finite participial construction in Early Latin. In contrast, in Classical Latin (e.g., see the following example from Caesar), Ablative Absolutes can appear with an ablative of agent:
Commisso ab equitibus proelio, ... (Caes. Civ. 1.41).
So my empirical question is: Are there any examples of "ablatives of agent" in Ablative Absolute constructions in Early Latin?
