[Anitius Severinus Boethius]

The Nephilim were on the earth in those days--and also afterward--when the sons of God went to the daughters of men and had children by them. They were the heroes of old, men of renown.

According to Genesis, the Nephilim were both pre and post flood. Goliath was a Nephilim (described as over 9 feet tall) according to the Bible.
