The 19th-century musicologist Alexander John Ellis maintained that Salinas really meant to characterize 1/6-comma meantone, and made a mistake due to his blindness.Sarmiento was elevated to the cardinalate that year, and Salinas took the holy orders and was granted an annual pension by Pope Paul III.While in Naples, he befriended Diego Ortiz, who served there as Kapellmeister; he also became acquainted with Orlando di Lasso and Tomás Luis de Victoria.In 1571, alongside Fray Luis de León and Diego de Castilla (then the rector of the University of Salamanca), he formed part of the jury for the literary prize that had been organised to celebrate the Spanish victory at the Battle of Lepanto and the birth of prince Ferdinand.In 1577 he authored his treatise De Musica libri septem, where he described meantone temperament for the first time.
