Pg. 344 of David Markson’s copy of The Classical Tradition: Greek and Roman Influences on Western Literature by Gilbert Highet:
On which Markson placed a line in the margin next to a paragraph on Edward Gibbon’s The Decline and Fall of the Roman Empire that starts with the sentence:
“One of the greatest intellectual and artistic achievements of the baroque age was a study of the conflict between the Roman empire and the forces that destroyed it.”
Edward Gibbon’s great intellectual and artistic achievement The Decline and Fall of the Roman Empire—no surprise—makes a handful of appearances in Markson’s Notecard Quartet…
“Lo, there is just appeared a truly classic work.
Wrote Horace Walpole—within one day of the publication of Gibbon’s Decline and Fall.”
Markson wrote on pg. 40 of The Last Novel.
Another mention of Walpole in relation to Decline and Fall happened in the previous novel in the tetralogy, Vanishing Point, on pg. 61:
“Horace Walpole’s cautious suggestion to Gibbon that certain lesser technical portions of the Decline and Fall might be boring.
After which Gibbon never spoke to him again.”
Also from Vanishing Point (on pg. 176):
“Given pause by the coincidence of the Declaration of Independence having been signed in the same year as the publication of The Decline and Fall of the Roman Empire.”
“Sailing the circumference of Lake Geneva, Byron and Shelley took time to pay homage at the house in Lausanne where Gibbon had written a great deal of The Decline and Fall.”
From pg. 120 of Markson’s This Is Not A Novel.
