Church Fathers on the Queenship of Mary My Question: Which Church Fathers thought of Mary as a Queen? 

The Church Fathers can be both early and late(max 500AD).
Many Church Fathers have written about the Queenship of Mary either directly or indirectly.

To start with, let us answer the question as to who are the Church Fathers according Catholicism?


  The Fathers of the Church are so called because of their leadership in the early Church, especially in defending, expounding, and developing Catholic doctrines. For the first two centuries, most of these men were bishops, although in later years certain priests and deacons were also recognized as Fathers. 
  
  The list includes such notables as: Clement of Rome (d. A.D. 97), Ignatius (d. 110), Polycarp (d. 155), Justin Martyr (the Church’s first major lay apologist; d. 165), Irenaeus (d. 202), Cyprian (d. 258), Athanasius (d. 373), Basil (d. 379), Cyril of Jerusalem (d. 386), Ambrose (d. 397), John Chrysostom (d. 407), Jerome (d. 420), Augustine (d. 430), Cyril of Alexandria (d. 444), Pope Leo the Great (d. 461), and Pope Gregory the Great (d. 604). 
  
  The Church demands four major characteristics to be exhibited in the life and works of an early Church leader if he is to be considered a Father of the Church. These are antiquity, meaning that he lived before the eighth century (the death of St. John Damascene [cir. A.D. 750] is generally regarded as the close of the age of the Fathers); doctrinal orthodoxy; personal sanctity; and approval by the Church. - Who were the Church Fathers?


Which Church Fathers thought of Mary as a Queen (prior to the year 500 AD)? 


  The Fathers of the Church unanimously called the Blessed Virgin Mary their Queen. Here is a sample of a few of the Fathers in their own words:
  
  St. Jerome tells us "We should realize that Mary means Lady in the Syrian language."
  
  St. Peter Chrysologus says "The Hebrew name ‘Mary’ means ‘Domina’ [Lady] in Latin. The Angel therefore calls her Lady so that the Mother of the Lord, whom the authority of her Son made and caused to be born and to be called the Lady, might be without servile fear."
  
  St. Ephrem has Mary saying:
  "Let Heaven sustain me in its embrace, because I am honored above it. For heaven was not Thy mother, but Thou hast made it Thy throne. How much more honorable and venerable than the throne of a king is his mother."
  
  St. Gregory Nazianzen calls her "the Mother of the King of the entire universe" as well as "Virgin Mother who brought forth the King of the entire world." - The Church Fathers On The Queenship Of Mary


The later Church Fathers are even more explicit in their wording as to Mary's Queenship as St. John Damascene calls her: "Queen, ruler, and lady".

Although not a Church Father, Catholic tradition sees Mary's Queenship in St. John's vision in the Book of Revelation 12:1-5: 


  “And a great sign appeared in heaven: A woman clothed with the sun, and the moon under her feet, and on her head a crown of twelve stars: And being with child, she cried travailing in birth, and was in pain to be delivered. And there was seen another sign in heaven: and behold a great red dragon, having seven heads, and ten horns: and on his head seven diadems: And his tail drew the third part of the stars of heaven, and cast them to the earth: and the dragon stood before the woman who was ready to be delivered; that, when she should be delivered, he might devour her son. And she brought forth a man child, who was to rule all nations with an iron rod: and her son was taken up to God, and to his throne.” - Biblical Basis of Mary's Royalty
