Atlántida

Atlántida
 

I was reading some poetry and came across the word Atlántida, which I was able to translate but not really make sense of in context. It's from Roberto Bolaño's Tres:
"La sombra que provisionalmente llamas autor apenas se molesta en describir cómo la desconocida arregló todo para su momento Atlántida."

From what I could find, Atlántida means Atlantis, and it's also the name of an epic Catalan poem by Jacint Berdaguer, but I couldn't really figure out what "su momento Atlántida" might mean. I'd appreciate any insight!

Para desaparecer? without notice and in an instant?

I suppose, sinking/dissapearing and nobody knows where she is.
Saludos :D

Yes, that's what I was thinking too: a defining moment of disappearance. I wonder if it would be good enough to say in English "her Atlantis moment."

Thanks!!
