The Special Art of SF: “Lord of Light” by Roger Zelazny

“Lord of Light” takes place maybe 100 or 200 years after the landing of humans on the planet where it takes place. A bottle of wine brought from Earth is still drinkable (though to be sure a precious relic); there is one survivor-in-the-flesh of the native entities who resisted human incursion. Also, the godhood of the "crew" arose informally - the "passengers" saw them wielding superhuman powers and doing battle with demonic adversaries, and so labeled them.
