In 1555, only a year after the first edition of the book, a sequel by another anonymous author was attached to the original Lazarillo in an edition printed in Antwerp, Low Countries. This sequel is known as El Lazarillo de Amberes, Amberes being the Spanish name for Antwerp.
Lázaro leaves his wife and child with the priest, in Toledo, and joins the Spanish army in their campaign against the Moors. The ship carrying the soldiers sinks, but before it does, Lázaro drinks as much wine as he can. His body is so full of wine that there is no place for the water to enter him, and by that means he survives under the sea. Threatened by the tuna fish there, Lázaro prays for mercy and is eventually metamorphosized into a tuna himself. Most of the book tells about how Lázaro struggles to find his place in tuna society.
In 1620, another sequel, by Juan de Luna, appeared in Paris. In the prologue, the narrator (not Lázaro himself but someone who claims to have a copy of Lázaro's writings) tells the reader that he was moved to publish the second part of Lázaro's adventures after hearing about a book which, he alleges, had falsely told of Lázaro being transformed into a tuna (obviously a disparaging reference to Lazarillo de Amberes).
