Short answers, pulled from the story.
Lancelot de Carle was a French scholar, poet, and diplomat who served as secretary to the French ambassador Antoine de Castelnau during the trial and execution of Anne Boleyn. He stood in the shadows of the Tower of London on the 2nd of May 1536 to witness the final hours of the queen.
The poem titled Epistre Contenant le Procès Criminel Faict à l'Encontre la Royne Anne Boullant d'Angleterre was dated the 2nd of June 1536. It was written in the immediate aftermath of the tragedy to blend diplomatic report with poetic lament.
Henry VIII ordered the suppression of all copies and the punishment of the author upon learning of the poem's existence in June 1537. The work detailed the arrest, charges of adultery and incest, and the grim execution of Anne Boleyn.
Historians believed the text was written by Crispin de Milherve until 1844 when a French scholar proved the attribution was doctored. Further comparison of genuine manuscripts in 1927 revealed the two poems were identical and written by the same hand, identifying Lancelot de Carle as the author.
Lancelot de Carle was born around 1508 in Bordeaux into a lineage of legal power and literary ambition. His father Jean de Carle served as the second president of the Parlement of Bordeaux from 1519 to 1521.
The work remained unpublished until 1545 and circulated in thirteen extant copies mostly in manuscript form. These copies were hidden in libraries from Bordeaux to Brussels before the poem was finally printed.
