Here are the matches for each description:
- This captures the moment right before a discus is released - Discobolus
- Another name for Myron's Disk Thrower - Discobolus (same as above, but referring to the artist)
- Most famous statues that survive today are this - Roman copies of original bronze Greek sculptures
Since the first two descriptions both refer to the same statue, "Discobolus" is the keyword for both.
