The Triqueta or Trinity Knot is steeped in history. The shape is one continuous line interwoven symbolising no beginning and no end. Originating in ancient Celtic times, the emergence of the Celts and the use of the knot across Europe is evident in the Bronze and Iron Ages. By 400 BCE, they existed in what is today, Austria, Britain, France, Netherlands, Belgium, Switzerland, Germany, Northern Spain (Galacia), Turkey, and Hungary. Over a 250-year period until 60 CE, The Romans completely conquered the Celts, pushing them to the fringes of northern Spain, northern France, and Britain. While Celtic imagery and symbols can be found across Europe they are most notably associated with Celtic Britain (Ireland, Scotland, and Wales).
The number three was significant to the world of the Celts: three stages of life; the three domains of earth, sea, and sky; as well as the past, present, and future. The same numerical significance existed for the Christian faith and therefore the Celtic Knot was adopted as one of its symbols and aligned perfectly with the concept of the Trinity.
The College adopted the symbol when it became Mary MacKillop College in 2009. The symbol’s Celtic origin is another link to Mary MacKillop who had a Scottish heritage. The top of the emblem shows a stylized flame that speaks of our motto, My Faith is My Light, and the passionate engagement with life and learning that we foster in the hearts and minds of the young women of Mary MacKillop College. In spiritual terms, it is the symbol of the Trinity and prosperity. In its interconnected and unbroken symmetry, it represents the triads of: Spirit, Mind, and Body; Power, Intellect, and Love; Past, Present, and Future. When the symbol is in full colour of red, green, and yellow, it represents the triad unity of the College Houses: Fitzroy, Penola, and McCormack, which again links to the fabric of the MacKillop story.
