The FirstBible of Charles the Bald (BNF Lat. 1) is a Carolingian-era Bible commissioned by Count Vivien in 845, the lay abbot of Saint-Martin de Tours, and presented to Charles the Bald in 846 on a visit to the church, as shown in the presentation miniature at the end of the book. It is also known as the Count Vivian Bible or the Vivian Bible. It is 495 mm by 345 mm and has 423 vellum folia.
It is also thought to be the third illuminated Bible to have been made at Tours following the Bamburgh and Grandval Moutier bibles.
