Mary as Queen Mother

In ancient Israel, the mothers of the kings were the queens of Israel. This began with King Solomon, who had a throne brought for his mother, Bathsheba, to be placed at his right hand (1 Kings 2:19). From then on, the mothers of Israel and Judah were queens. I presume this was the case because the kings often had multiple wives but one mother.

Jesus is our King of Heaven, who sits on the throne for all eternity. Following the tradition of ancient Israel will make Mary of Nazareth the Queen of Heaven. Thus, we see her depicted with a crown, sitting on a throne with or next to her Son, Jesus.
