Because the ownership and therefore the location of the MS is known it is of immense importance in understanding the origins of Freemasonry before the Grand Lodge era (from 1717). The Airlie MS has been analysed and discussed in considerable detail in Ars Quatuor Coronatorum (AQC), Vol.117.
Of all the MSS of the Scottish School only the origins of the Airlie MS (1705) are known with certainty. It is named after the family who owned it - the Earls of Airlie.
