Ventre-saint-Gris!
The usual oath of Henri IV. About equal to Corpus Christi. A similar juron is Par le ventre de Dieu (Ventre-dieu! or Ventrebleu!). Cris for Christ is familiarised by our common phrase the criss-cross or cris-cross row; and if saint refers to Christ we have a similar phrase in St. Saviours. Rabelais has Par sainet Gris; and William Price, the Arch-Druid, who died in 1893, describes himself in the Medical Directory as Decipherer of the Pedigree of Jessu Grist. Chaucer writes the word Crist.

But a correspondent of Notes and Queries sends this quotation

Ce prince [Henri IV.] avoit pris lhabitude demployer cette expression. Ventre-saint-Gris, comme une espece de jurement, lorsquil etoit encore infant, ses gouverneurs craignant quil ne shabituâl à jurer lui avoient permis de dire Ventre-saint-Gris, qui étoit un terme derision quils appliquoent aux Franciscans de la couleur de leur habillements.Feb. 10th, 1894, p. 113.
