So here might be a place in which to ask: Eça de Queiroz nentions "the poet of Vozes d'Aurora", in a novel (Os Maias), but I couldn't find any results on it, is it a fictitious creation?
I was raised in Portugal so I had to study the Maias in school and read multiple analysis. This book has been over analyzed to death in Portugal even though you will probably only find most of those analysis in Portuguese
