Pierre Thomas, sior of the Ditch , born the April 6th 1634 with Rouen and dead the November 4th 1698 with Paris, is a Savant and author French.

His/her father, having sent Master of the accounts in Rouen, it child at the Jansenist S to Port-Royal to be informed there, it took there taste with the life of recluse and even of hermit. This inclination led it thereafter to be established near Port-Royal-of-Fields where it was related to the Dwarf of Tillemont, Singlin, Arnauld d' Andilly and Lemaistre.

Established with Paris in 1661, it was stopped with Lemaistre de Sacy in 1666 and was exiled, after one month of imprisonment to the Bastille, in Normandy in its ground of the Fossé close to Forging mill-the-Water. Thereafter, it paid annual visits in Paris during the bad season.

Independently of its collaboration with Sacy on the Bible of Mons, of the Ditch was the author of some hagiographies and Mémoires (1697 - 8) that Holy-Beuve extremely rented like reflecting the life of Port-Royal admirably.

It translated Hebrew into French and writing under the pseudonyms of Pierre Thomas Beaulieu and Pierre Thomas La Motte.
