Can two different pronouns (that, who) be used to refer to the same antecedent (a statue representing a person)?
Solution 1:
To answer the OP's question:
Yes, it is fine to use different pronouns to refer to the same antecedent.
In the OP's example, the antecedent refers not to a statue but to a female figure in a statue. So the appropriate pronouns are "that" and "who". If the antecent referred to the statue itself, the appropriate pronouns are "that" and "which". For example, the statue that the OP mentioned, which was sculpted by XXX, depicts YYY being crowned by a female figure representing Victory.
