Os Rubaiyat de Manuel Bandeira e de Torrieri Guimarães. Denise Botman.
In: Revista InComunidade, Edição de ABRIL de 2017.

Summary:
This article discusses a number of peculiarities in the translations into Portuguese by Bandeira and by Guimarães, both said to be based on the French translation by Toussaint. After examination and comparison of the text it appears that the translation by Guimarães is not based on Toussaint, as claimed by the translator but on Bandeira, which is considered to be an example of plagiarism or fraud, or both.
