Thanks both. I had an inkling about 36A, but couldn't find anything that would then fit 30D - which does seem a bit of an odd clue, although I can now see how it works.
Nelson, am up for a big hint if you feel you could share a little. Perhaps where the perimeter quotation begins...or whatever you think appropriate,....
36 is just the two letter abbreviation for It, attraction, that's only ever used in crosswords, followed by a two-letter word for the soul in Egyptian religion. The resulting word/answer is another word for Sheba, Yemeni people.
