Many of us have the image of Tísner on his head: that eye patch, that pear-shaped beard, that friendliness. We've seen him in some television interviews, we know he was the brother-in-law of Pere Calders –with whom he had gone into exile in Mexico– and also that he did the crossword puzzle of The Vanguard before Màrius Serra, but... what do we know about Tísner the writer? At most, that he is the author of Words of Opóton the Elder, his best-known novel, an alternate history in which the Aztec emperor Moctezuma conquers Europe; but this is not the only book he wrote.
