Does Odysseus meet the cyclops before or after he lands on island of phaeacia how do you know?

After. This can be inferred from Book IX of Homer's _Odyssey_. After Odysseus and his men escape from the cave of the giant cannibalistic Cyclops Polyphemus, they return to their ship and set sail. A storm at sea blows them off course, however, and the group washes up on the island of the Phaeacians.
