William Blake (1757 - 1827) was a real-life English poet who is frequently mentioned in The Mentalist, specifically concerning Red John. The two poems quoted so far that bear significance are "The Tyger" and "Cradle Song".
A name of a Red John suspect, Brett Partridge, recall the title of his painting "A Brace of Partridge".
Another episode that remind Blake is The Great Red Dragon: Blake paints a series of pictures inspired at this character, by the "Book of the Revelation" (also known as "St. John's Apocalypse", from the Bible).
