Scesis Onomaton emphasizes an idea by expressing it in a string of generally synonymous phrases or statements. While it should be used carefully, this deliberate and obvious restatement can be quite effective:

• We succeeded, we were victorious, we accomplished the feat!
• Ah sinful nation, a people laden with iniquity, a seed of evildoers, children that deal corruptly. --Isaiah 1:4
• But there is one thing these glassy-eyed idealists forget: such a scheme would be extremely costly, horrendously expensive, and require a ton of money.
• Wendy lay there, motionless in a peaceful slumber, very still in the arms of sleep.
• May God arise, may his enemies be scattered, may his foes flee before him. --Psalm 68:1 (NIV)

Scesis onomaton does have a tendency to call attention to itself and to be repetitive, so it is not used in formal writing as frequently as some other devices. But if well done, it is both beautiful and emphatic.
