CXXXVI
The island of the amorous deity
          upon them an air, in her first port,
Which not alone to man does injury,
But moulders iron, and here life is short;
-- A marsh the cause, -- and Nature certainly
Wrongs Famagosta, poisoning, in such sort,
That city with Constantia's fen malign,
To all the rest of Cyprus so benign.
