The Anchor is a symbol of well-grounded hope and a life well spent. It has long been a symbol of stability. It is believed that the anchor became a symbol of hope with early Christians. Drawings and carvings in the catacombs of Rome depict the early usage of this symbol in the Christian faith.
Early Freemasons were enamored with Antediluvian, or pre-flood, symbolism. This included Noah’s Ark, rainbows, doves, and more. The ark reminds us of the rough and unpredictable seas that we have to traverse in life. A strong belief in deity helps provide the safe passage.
“The anchor and the ark are emblems of a well-grounded hope and a well-spent life. They are emblematical of that Divine ark which safely wafts us over this tempestuous sea of troubles, and that anchor which shall safely moor us in a peaceful harbor where the wicked cease from troubling and the weary shall find rest.”
(quote: Albert Mackey, Encyclopedia of Freemasonry)
