Riddle clue: Within the Birthplace of Apollo, seek the Temple of Delians. There is a secret passageway to an underground tomb behind a bronze statue. Find me in a pile of apples guarded by snakes.
Grave Discovery riddle solution
This clue is very sneaky, and incredibly easy to miss. The Temple of Delians is the name for the largest temple of Apollo in the Birthplace of Apollo (even though the game doesn't technically use that name while you're exploring). Look for a lower level of the temple to the rear of the bronze statue (as shown in the screenshot).
This area is laid out like a Tomb, but it doesn't count as one. There will be a smaller bronze statue in a darkened alcove with some blue curtains behind it. Light a torch, go down the stairs, turn right and go down the next stairs. Drop down the hole in the floor, kill the snakes and claim your reward: increased Seconds Burning Duration.
