On Poems Published in Ahana and Other Poems
On Two Translations of Revelation [2]
The translation is very good poetry. It is perhaps not quite the original, for what you describe is an obviously superhuman figure while the details in the poem might be those of a human figure and it is something subtle and not expressed but only hinted which gives the impression expressed only at the end that it is someone of the heavenly rout. That however does not matter; your version can be taken as an adaptation of the idea in the poem and not a strict translation of it.
