ante diem vii kalendas septembres
- 55 B.C. — Julius Caesar invades Britain, but doesn’t stick around very long
- 1875 — Birth of John Buchan, 1st Baron of Tweedsmuir and Governor-General of Canada … and author of a decent biography of Augustus

quidquid bene dictum est ab ullo, meum est
ante diem vii kalendas septembres
And don’t forget that Buchan also wrote suspense – “The Thirty-Nine Steps”. From what I remember in school, he was considered a pretty good governor general, and encouraged the idea of a Canadian identity as separate from that of Britain. Unfortunately he died in office.
