As his contribution to Anglo-Islamic understanding, my husband asked me what the connection was between genius loci and the genie in the bottle. I couldn’t say that I knew, although I don’t suppose Osama bin Laden knows either.
Genius is complicated semantically. I think it has gone a step further than the OED suggests, now signifying an Einsteinian ‘brains’, not so much in contradistinction to a man of talent as 100 years ago. In Latin it meant first the tutelary deity accompanying a man through life, like Socrates’ daemon. The Middle Ages entertained what was said to be a Pythagorean belief in a good and a bad genius that lead us on to good or ill actions. It doesn’t quite fit in with the notion of a guardian angel because, although devils may teem, only the chief Devil or Satan is usually credited with temptation.
A genius might haunt a place and be a genius loci, yet here again is ambiguity, for a place could have its spirit without that bundle of associations being attributed to a personified immaterial spirit.
In Arabic, which I do not know, jinn (or djinn) is a collective plural for spiritual creatures less exalted than angels. They seem to have a material admixture, at least in popular understanding. The singular is jinni, but English people doggedly stick to djinn in the Arabian context.
The fateful step of rendering jinni as genie was taken by translators of the Arabian Nights into French in the early 18th century. It sounded similar and had similar meanings to the French version of genius, even though there was no etymological relationship between the words.
My copy of the Arabian Nights at home is the version of Edward Forster made in 1802.
