August The Twenty-Third

ALMIGHTY God, who hast planted the day-star in the heavens, and, scattering the night, dost restore morning to the world; fill us, we beseech Thee, with Thy mercy, so that, Thou being our Enlightener, all the darkness of our sins may be dispersed, through our Lord Jesus Christ - Amen.

-- SARUM BREVIARY, A.D. 1085
