Which publisher issued the first part of Don Quixote in 1605?

Francisco de Robles issued the first part of Don Quixote in 1605.

Robles was a Madrid bookseller and publisher who acquired the rights to Cervantes’s manuscript in July 1604. He arranged for the work to be printed in Madrid and brought the first part to market early in 1605.

The distinction between publisher and printer explains a frequent quiz trap. Robles was the publisher-bookseller responsible for issuing the book, while Juan de la Cuesta operated the Madrid print shop that produced the physical copies. Both names are therefore closely tied to the first edition, but they held different roles.

The first part was titled The Ingenious Hidalgo Don Quixote of La Mancha. It became an immediate success, prompting unauthorized editions and later encouraging Cervantes to publish an authentic second part in 1615 after a spurious continuation appeared in 1614.
