As a member of the Bullingdon ClubatOxford, Mount enjoyed a certain notoriety after being rolled down a hill in a portable toilet. "It was like coming out of Dracula's coffin", he told
The New Yorker in 2007.[4]
After Mount wrote in The Spectator (2004) lamenting the supposed demise of Classics teaching in the UK, and dismissing the Cambridge Latin Course, The Spectator published a riposte from the Dean of Wadham, James Morwood, saying: "His denunciation of the Cambridge Latin Course as 'the evil Latin-for-idiots school textbooks' is blind to the fact that it was this very course which rescued Latin from an apparently terminal decline in the 1960s."[14]
The Classical theme recurred in 2007 with the publication of Mount's best-seller, Amo, Amas, Amat ... and All That. Although this book repeated his ridicule of the education system, it was his exposure of the elitist implications of the study of Latin which “caused a measure of class controversy in the U.K."[4]
"Class war with classicists" was the headline in Spectator Australia after Mount wrote a Telegraph article in 2015 saying classics exams had been dumbed down. Mount detailed the abuse he received, including:『A classics student at King’s College London called me an 'antediluvian ape'. A classics teacher at Durham Sixth Form Centre predicted my next book would be 'bowel-achingly derivative'.』Mount fought back with: "The classics trolls instantly associate any dumbing down suggestions with far-right fogeyish snobbishness."[16]
Amo, Amas, Amat ... and All That, published by Hyperion in 2007, was a best-selling popular reference on the Latin language whose title harks back to Sellar and Yeatman's 1066 and All That. Dedicated to his brother (William) and sister (Mary), the book introduced the basics of Latin grammar and combined his own personal memories, Latin references in popular culture, and stories about ancient Rome. In it, he reveals his prep school nickname of "Mons" (Mons, montis m. mountain). Published in the United States as Carpe Diem: Put a Little Latin in Your Life.
