Bruno (the Itallian CAS translator) has come up with an interesting question - he asked me:

"What's the mean of the terms "Aidennic" ? I try to translate it but I have
no found this word."

"Aidennic"
Appears in The Hashish Eater:

And tread them to a fragrance that pursues
To win the portico, whose columns, carved
Of lazuli and amber, mock the palms
Of bright Aidennic forests-capitalled
With fronds of stone fretted to airy lace,
Enfolding drupes that seem as tawny clusters

I emailed him the answer:

"I don't have a definitive answer Poe used Aidenn as a poetic spelling of Eden (Garden of Eden) - so perhaps CAS is the same. I'm going to post your question on the ED message forum and see if any one else has any thoughts."

so any one?

In Arabic "Aidenn" means paradise. It alludes to the Garden of Eden

ok think that answers mine and Bruno's question.

Your analysis is correct - CAS would have known both sources, since the
source appears in the "Hernia" edition of the dictionary, and the encyclopedia he read as a boy - It is likely that Poe knew the Arabic
source as well, since "things eastern" were all the rage in the years
following the discovery of the rosetta stone, and the development of a
lively trade in antiquities - including documents - also probably in
some commentary of Fitzgerald's on translating the "Rubaiyat" of
Omar Khayyam -- much the rage in the 19th century, and the subject
memorizing by college boys - especially the stuff on drinkings - Clark
and I went through the whole thing one night from memory while comparing
old Fitz with an excellent "new" translation that still lies about here
somewhere.

I've always assumed that Smith studied from a first-edition Webster's
__New International Dictionary__ -- am I correct? In either case,
what's the "Hernia" edition of the dictionary you're referring to?
