Exstracts From the Catholic Encyclopedia:
First century:
Seeing that this doctrine is not contained, at least explicitly in the earlier forms of the Apostles' Creed, there is perhaps no ground for surprise if we do not meet with any clear traces of the cultus of the Blessed Virgin in the first
Christian centuries.
AD 403:
Hence Epiphanius laid down the rule: "Let Mary be held in honour. Let the Father, Son, and Holy Ghost be adored, but let no one adore Mary"
?
St. Augustine in a famous passage (De nat. et gratis, 36) proclaims Mary's unique privilege of sinlessness
Middle ages:
It seems somewhere in these centuries Our lady's altar becomes available?
Phrases like:
Mary is there called "Mistress of the Heavens, Mother of the Heavenly and earthly Church, Recreation of Life, Mistress of the Tribes, Mother of the Orphans, Breast of the Infants, Queen of Life, Ladder of Heaven." This composition may be as old as the middle of the eighth century.
while Christ is continually referred to as "Jesus Mac Mary" (i.e. Son of Mary).
Later Middle Ages:
Even in Aldhelm's day
Our Lady was besought to hearken to the prayers of those who bent the knee before her shrine.
(Also in this time more and more miracles are being claimed regarding Mary. Most of them strange types of things which profits nobody nothing and doesn't give any glory to God)
And by the end of the Middle ages things like a Mary-Mass was "universal"
To me personally it seemed that things changed to atleast some extent over the last 2000 years.
