"The Prisoner", towards the eponymous series. It's rumoured that Patrick McGoohan himself, when the band asked for permission to use lines from the show, said "What was the band's name again?...a rock band, you say?...do it!". Picture those words in your mind along with that trademark cadence to Patrick McGoohan's voice and you're spot on.
The eponymous track is inspired by a nightmare bassist Steve Harris had after watching the film Damien: Omen II. According to him, the lyrics were also influenced by Robert Burns' "Tam O' Shanter".
The spoken introduction by Barry Clayton was King James' Version of "Revelations 12:12" and "Revelations 13:18".
Dickinson's scream seems to be inspired by Roger Daltrey's scream at the middle of "Won't Get Fooled Again".
"Run To The Hills" is about the native-american massacre. The videoclip features images from various films.
"Still Life"it is inspired by Ramsey Campbell's "The Inhabitant of The Lake."
Nicko's hidden backwards rant in the beginning of the song is taken from the satirical album "The Collected Broadcasts of Idi Amin" by Bird and Alan Coren.
"Sun And Steel" is about legendary Japanese Swordsman Miyamoto Musashi. Several passages of the song also references Musashi's book "A Book Of Five Rings."
"To Tame A Land", towards Dune. It's a shame Frank Herbert wasn't quite so accommodating regarding Dune - the song had to be renamed To Tame A Land. This lack of accomodation was "mentioned" by Bruce in the 1983 World Piece Tour:
Next song is all about a gentleman who wrote a science-fiction book called Dune(...). He's an American called Mr. Frank Herbert, this particular gentleman, alright? And Mr. Herbert, as it turns out, is a bit of acuntactually, because he... among other things he said that if we called this track that we wrote on the album "Dune", that he'd sue us and stop the album coming out, and all kinds of very unpleasant things... So we had to re-title the track which is on the new album, and we had to call it To Tame A Land.
Powerslave
"The Duellists" is inspired by Ridley Scott's movie of the same name.
The coverart of the album references a lot of Maiden's stuff.
"The Loneliness of the Long Distance Runner" takes it's title from the book by the same title by Robert Heinlein. It's also based on the Alan Sillitoe short story.
