Poetry. Singladura. Borges.

Hello,

I am trying to translate the poem Singladura by Borges. I am having trouble with the first clause:

El mar es tina espada innumerable...

'tina espada' translated literally is bathtub sword, no? I don't understand how to logically translate the two words...

Thank you all for the help! :)

Hi there!

It is a typo. The original reads "El mar es una espada innumerable y una plenitud de pobreza."

Cheers!
