What is the history of the Let us Pray prayer?

Let Us Pray

        O God, whose only begotton Son,
        by His life, death, and resurrection has
        purchased for us the rewards of eternal life,
        Grant, we beseech Thee, that whilst meditating
        upon these mysteries of the most Holy Rosary
        of the Blessed Virgin Mary, we may 
        imitate what they contain, and obtain what
        they promise: through the same Christ our Lord.

        Amen.

**When did it become part of the Rosary and where did it come from?

Thanks.**

The prayer comes from the Divine Office on the 7th of October, the feast of the most holy rosary of the Blessed Virgin Mary. It is said at the end of several of the hours. I assume it was piously introduced to the rosary after it was put into the Divine Office.

It’s NOT called “let us pray.” Its name is the “Prayer After the Rosary.”

The words “let us pray” precede many of the prayers said when there is a group praying.
