Question

which technique does homers use at ths beginning of book 9 of the odyssey to inform readers about ulysses adventures after the trojan

Answer 1

I believe the answer is: In medias red

In medias red is characterized by making exposition that bypassed by the combination of both descriptions of events that already happened or flash backs. This would create a non linear story line that help audiences understand why a certain thing happen to characters at current time.
