That have any relation to the word Armageddon as well?
Yes ancient cultures are fascinating and should be more relevant in the zeitgeist; especially in respect to their knowledge and sophistication in thinking.
Armageddon comes from "Har Megiddo," an actual place of strategic importance and hence the site of many battles named before the name took on apocalyptic connotations.
to add to wl's comment, armageddon took on the meaning of an apocolyptic battle because it was mentioned in the Book of Revelations as the site of the final battle.
"Apocalypse" is also a great word. It means literally "the lifting of the veil" or removing the covering, so you can see what is underneath.
True story: I was once on vacation in Greece, and saw a strip club called Apocalypse. Based on the signage, they meant that in the sense of revealing hidden pleasures rather than some final battle, but I could also see some ways that visiting that club could lead to a nasty showdown.
It's exactly the same as "revelation". That word also comes from re-, "to strip back", and "veil". The strip club being called "revelation" also has the same double entendre.
A strip club being called "αποκάλυψη" would bring to mind, literally a revelation of something.
