The eagle and the snake are a symbol on Mexico’s flag, whose origins are unclear (reminding me the origins of “gringo”). They are also the title of a revolutionary novel, written by Martín Luis Guzmán, published in 1928. The Mexican Academy of the Spanish Language asked Susana Quintanilla to compile a critical edition of El áquila y la serpiente. Today, she presented a moving account of the effort involved. During her talk, she showed what looked like a published book, although I couldn’t find evidence of its existence online. I can only recommend, instead, her article in Letras Libres (in Spanish).
