Bibles and other ritual objects were strewn about on the dusty grounds-pitiful relics that seemed to never have had a home. all this under a magnificent blue sky."" this is an example of what literary device?

In this case, I would say that Elie Wiesel, the author of "Night", uses two literary devices, one that superimposes over the other, but both are present here:

1. The least obvious one is personification. This one is achieved when Wiesel mentions the Bibles, and other ritual objects, and then mentions them as pitiful relics that do not have a HOME. Mentioning having a home, in relation to an object, is assigning a human characteristic to that object, and this is a condition to apply personification. It seems that Wiesel is talking about these relics as something that NEEDS a home.

2. The second, and most important and relevant one here is: Irony. Irony is achieved almost throughout the whole of "Night" but never more so than in this particular portion, which is also a direct quote from Elie Wiesel, the author and main character, himself. This irony is reached through two things, he use of the word "relics" and then the sentence "All this under a magnificent blue sky". The irony comes from learning that such precious objects to Jews, as a Bible, have been turned into something as unimportant or meaningless as a relic, and second, with the use of "All this under a magnificent blue sky" contrast the irony of the destruction and caos  mentioned before, and the beautiful sense of wonder, and even hope, that seeing a nice, sunny, blue sky can generate.

b)metaphor

explanation:

when reading the sentence carefully it says,"hope is a thing with feathers" it's like saying: hope is a thing like feathers

get what i'm saying? instead of using a smilie like or as they use "with"

it would be nice enough if i got .

"the sandy walls seemed to collapse in on themselves"

and

"the bloodshot waters seemed to have no bottom"
