Analysis of Epitaph Of Constantine Kanaris

I am Constantine Kanaris:
I, who lie beneath this stone,
Twice into the air in thunder
Have the Turkish galleys blown.

In my bed I died-a Christian,
Hoping straight with Christ to be;
Yet one earthly wish is buried
Deep within the grave with me-

That upon the open ocean
When the third Armada came,
They and I had died together,
Whirled aloft on wings of flame.

Yet 'tis something that they've laid me
In a land without a stain:
Keep it thus, my God and Saviour,
Till I rise from earth again!
