The Great Stockholm Fire of 1759 was the city’s greatest fire since 1686.
 It raged in the Eastern Södermalm on Thursday July 19 and over the following night, reduced about 20 blocks with about 300 houses to ash, and rendered about 2000 persons homeless.
 While no deaths were reported, there were 19 injuries.
 In Sweden, the fire is named "Mariabranden" (Swedish "brand" = fire) after the Maria Magdalena Church, which was severely damaged.
 Outside Sweden, the fire is most famous because an occult anecdote claims the scientist and mystic Emanuel Swedenborg by a sort of clairvoyance could ”see” the fire from Gothenburg.

The Sense of Beauty is a book on aesthetics by George Santayana.
 The book was published in 1896 by Charles Scribner's Sons, and is based on the lectures Santayana gave on aesthetics while teaching at Harvard University.
 Santayana published the book out of necessity, for tenure, rather than inspiration.
 In an anecdote retold by art critic Arthur Danto of a meeting with Santayana in 1950, Santayana was reported to have said that "they let me know through the ladies that I had better publish a book... on art, of course.
 So I wrote this wretched potboiler."

 Extracts from the book were published in the "Daily Mail" on 21 September 2015, prior to its publication.
