What is depicted on this piece of artwork? Another piece in the belongings of my late grandmother may she rest in peace.

This particular piece is a very beautiful piece in my opinion. This is a part of 7 pieces in total.

I am really intrigued by the artwork itself.

Is it possible for someone to identify this scene?
The picture depicts the Coronation of the Virgin or Coronation of Mary.


  The Coronation of the Virgin or Coronation of Mary is a subject in Christian art, especially popular in Italy in the 13th to 15th centuries, but continuing in popularity until the 18th century and beyond. Christ, sometimes accompanied by God the Father and the Holy Spirit in the form of a dove, places a crown on the head of Mary as Queen of Heaven. In early versions the setting is a Heaven imagined as an earthly court, staffed by saints and angels; in later versions Heaven is more often seen as in the sky, with the figures seated on clouds. The subject is also notable as one where the whole Christian Trinity is often shown together, sometimes in unusual ways. Although crowned Virgins may be seen in Orthodox Christian icons, the coronation by the deity is not. Mary is sometimes shown, in both Eastern and Western Christian art, being crowned by one or two angels, but this is considered a different subject. 
  
  The belief in Mary as Queen of Heaven obtained the papal sanction of Pope Pius XII in his encyclical Ad Caeli Reginam (English: Queenship of Mary in Heaven) of October 11, 1954. It is also the fifth Glorious Mystery of the Rosary. The Roman Catholic Church celebrates the feast every August 22, where it replaced the former octave of the Assumption of Mary in 1969, a move made by Pope Paul VI. The feast was formerly celebrated on May 31, at the end of the Marian month, where the present general calendar now commemorates the Feast of the Visitation. In addition, there are Canonical coronations authorized by the Pope which are given to specific Marian images venerated in a particular place. - Coronation of the Virgin


The Latin (Converte nos)is from Psalm 84 and is part of Complines and  the Little Office of the Blessed Sacrament amongst other places in the Divine Office of the Church:


  V. Converte nos Deus salutaris noster: 
  
  R. Et averte iram tuam a nobis. (Psalm 84:5)


In English:


  V. Convert us, O God our Savior.
  
  R. And turn away Thy wrath from us.
