James Fitzmaurice-Kelly, Fray Luis de León: A Biographical Fragment
“ Meanwhile Luis de Leon (who, like Domingo de Guzman, was perfectly innocent of any share in these clandestine manœuvres) had taken possession of the Biblical Chair at Salamanca by reading himself in on December 7, 1579. Hitherto his reputation, great as it was, had been more or less local: that is to say, it depended mainly on his University lectures, which were exploited by certain unscrupulous persons. It was not till 1580 that, at the express command of his superior, Fray Pedro Suarez, [215] he issued his first book: a Latin commentary on the Song of Songs. ”
