How did Greek influence English?

[I lost the Reply that I had written, essentially:
Furthermore, we have "Sunday" which is basically a translation of the Roman/Latin "Solis dies". However, there is a complex Greek history behind this very name. I'll try to make it short.
The very ancient Greeks discovered seven planets (wandering stars) or deities, before the Baylonians and the Romans, while they had a lunar calendar; that is, they measured time by lunations (each consisting of 28 days). Now, at the beginning of each month, the seven gods were celebrated, beginning with the Moon and ending with the Sun (in Greek, Helios but, later Apollo as the Sun-god, represented as the colossus of Rhodes occupied by the Peloponnesian Dorians but destroyed by an earthquake). The seven feast-days became what we call the "week" among all Greek-speaking peoples such as the future Romans and the pre-Semitic Hebrews and, of course, in the Romance [Romanesque] languages (Italian, Spanish, French, etc.) and languages influenced by ecclesiastical Latin, such as English. //The Hebrews imagined that their deities (the Elohim) fashioned the world in 6 days and rested on the 7th day, which for the people became the holy-day or Sabath. The Christians followed suit but changed Sun-Day into "Day of the Lord" [Domini-ca], and Satur(ni)-day to Sabat(o), thus virtually reducing the work-days to 5. (The eve of a great Holy Day, such as "all-saints day (Nov. 1)" was considered also important or holy, as in the case of the English Hallow-ween or, in southern Europe, the night when some of the Departed may come back to visit; a table with food and wine is left prepared for them -- which is in the pagan tradition of Hekate's Suppers prepared for her, the Queen of the Night, in case she decided to come.) // A footnote: In a crypt (catacomb) under St. Peter's basilica in Rome there is a second-century mosaic that represents Jesus as Apollo (the sun-god) driving his chariot across the sky, for, after all, he had been conceived (in the Greek Gospels) as the light of the world and, as such, the Soter (Savior)....
