Who canonized Saint Anne?

St. Anna was the prophetess mentioned in the second chapter of St. Luke's Gospel. This was many centuries before the canonization process came about.
Saint Anne, the mother of the Virgin Mary, is sometimes referred to as Saint Anna or even Hannah. Old Testament personages are generally not accorded the title of saint as Anna the prophetess. Saint Anne has been venerated by the Church since the earliest days and her cult was extended for the Universal Church in 1584.
