OH… I hear ye.
Where does he fit on the Atticist - Katharevousa - Dhimotiki spectrum? Peter Green seems fond of Cavafy, and quotes him often in Alexander to Actium, suggesting at one point that Callimachus and Cavafy had the same taste in men (unavailable and maybe a bit dangerous).
Hmmm, I would say that Kavafis (or Cavafis) is in a category all of its own. He is more interested in what suits him than whether it is Katharevousa or Demotike he is using.
He loved Alexandria and was fascinated by Hellenistic times (especially Egypt during roughly that period) so maybe that is why Green refers to him.
This (translation )is written making heavy use of Katharevousa for example.
This one (translation) uses types of both in a sort of equal manner
Lastly in this one (translation) which by the way is one of his most famous poems he is using demotike more than Katharevousa.
As for his tastes, yes, many of his poems (not published or even acknowledged by him) make allusions to his “forbidden” passion.
Here’s wikipedia’s article on him (I checked it 
).
Mind you, we’re talking about MG pronunciation in all cases (here’s a decent recitation of the second one)
I should stop before I link to every single one of his poems

Great book
I’m reading Amanda Elyot’s “Memoirs of Helen of Troy” and it’s surprisingly good. She isn’t a classics person, & sometimes it shows, but she does O. K. I would recommend it-she does get the female perspective right without distorting things. The writing is good & the sex scenes are pretty good. Paige.
