Michel Tronchay

Michel Tronchay (October 1668 – October 30, 1733) was a French Catholic priest, writer, philosopher, and the secretary of French historian Louis-Sebastien Le Nain de Tillemont. After Tillemont's death, Tronchay completed and published volumes 6–16 of Memoires pour servir a l'histoire ecclesiastique des six premiers siecles, a history of the first six-centuries of the Christian church. He also completed and published the final volume 6 of Histoire des empereurs et autres princes qui ont regne pendant les six premiers siecles de l'Eglise, a history of the Roman Empire. This work was often cited by Edward Gibbon in his Decline and Fall of the Roman Empire.

Tronchay published a biography of Tillemont in 1706, Idee de la vie et de T esprit de M. L. de Tillemont, and a history of Port-Royal-des-Champs Abbey titled Histoire abregee de l'abbaye de PortRoyal.

Tronchay was born in Mayenne in October 1668. He died October 30, 1733.
