Tony Prost writes as follows:
"Virtually nothing is known of Nonnos of Panopolis, except the attribution to him of the 48 book Dionysiaca, and the 21 Book Paraphrase of the Gospel of John. Some experts dispute that the same person wrote both poems. However there are enough unique words which appear in the Paraphrasis which have parallel citations only in the Dionysiaca to make the transmitted provenance convincing."
Prost also includes a translation of about 1/3 of Nonnos' Paraphrase. You should read the beginning of Chapter 2 (lines 1 - 57; down to "Galileans with long Hair".
In this selection, phrases in the first and last lines, viz., "Dawn painted rose the Rocks" and "Galileans with long Hair" pick up, with modification, well-known Homeric formulas. The first is illustrated at, e.g., H & P, p.439, line 104 (in Odyssey, Book 9), "As soon as Dawn's rose fingers touched the sky". The other formula (a modification of a Homeric reference to the Achaians) is illustrated at, e.g., H & P, p. 362, line 58 (in Iliad, book 8), "Akhaian fighting men with flowing hair".
