In Christianity,
sculpture of old man with longer beard is Father in heaven.
sculpture of young man with slight beard is Word incarnated on earth as Jesus.
sculpture of a dove would be Holy Spirit manifesting into his bird form.
Since Zeus on the other hand is old looking God that has many children and its been quite a culture for Romans about tradition of gods in human appearance in heaven.
The Romans must have love when they heard about story that a couple of Gods in heaven manifesting themselves on earth to do a suicidal act for sake of giving salvation to humanity
