In one of his letters to Fronto, Marcus wrote: “So passionately, by Hercules, am I in love with you, nor am I frightened off by the law you lay down, and even if you show yourself more forward and facile to others, who are non-lovers, yet will I love you while I have life and health.” The Correspondence of Marcus Cornelius Fronto, ed. C. R. Haines, 1919.
