First of all, I'm very happy that you replied to me, thanks!!! I thought I might have stepped on your toes by asking for an elaboration on the meaning, some writers don't like that... they seem to think I need to figure it out on my own.lol I think that you're words only make me appreciate your poem even more!!!
Secondly, I found your intentions of the Siren representing something mythological and Columbus etc etc to be very interesting!! I did think of Columbus when I re-read a few times because of the reference to caravelles and the wonderful imagery in the 2nd and third lines but I also think that the lines (which I love btw)
"like a siren seeking to entice
make accursed the enticed."
made me think of the siren as perhaps representing the objects and things that that the natives had not seen before and were 'enticed' by... the ignorance of the Europeans thinking that they were 'accursed' because they were different when really they became 'accursed' (died of diseases, were forced into religions and were held captive and other such atrocities) because they were enticed by, and reached out in friendship to, the Europeans.
Either way, those lines are very powerful and no matter how interpeted I think it still reflects your greater meaning.... one last time, I will say, I really loved this poem, thanks for sharing it as well as your ideas, I truly appreciate it.
