Career
Born in Saye, Normandy, he rose from obscurity to become Sheriff of Cambridgeshire as early as 1071 until at least 1090. He treated Cambridge (then known as Cantebrigge or Grentebrige) as his own, knocking down 27 houses to build Cambridge Castle (probably initially of wood), confiscating land, building mills, seizing goods and raising taxes. The Abbot of Ely described him as "A hungry lion, a ravening wolf, a cunning fox, a dirty pig and an impudent dog".
After Picot"s death the canons were moved to nearby Barnwell to found Barnwell Priory.
His estates were forfeit and given to Pain (or Paganus) Peveril who had been the standard bearer to Robert Curthose in the Holy Land.
