Motif in "Oedipus the King"?

Question

Motif: "an image that repeats throughout a text"

according to this definition, are "sight and blindness" appropriate motifs? i was confused because sight and blindness are not actual images...

Answer 1

Do unto others as you would do your mother?

Answer 2

Yes, sight and image are motifs. So is suicide. So are graves, tombs and burials.
