What can we infer from the line, "Here was a man who fired his arrows well"?
Oedipus was good archer
Oedipus was highly skilled in many things
Oedipus was a good statesman but a bad father
Oedipus killed Laius with an arrow
I believe this is stating not about the physical arrows, but his skill set. So therefore I think it's option 2 "Oedipus was highly skilled in many things"
