The origins of Freemasonry in its modern form - as distinct from the practical art of the stonemasons - is a
vexed question. Precisely how 'speculative' Freemasonry (the philosophical and ceremonial form familiar today)
evolved from 'operative' Masonry (the craft of the stonemason) is still the subject of much debate. However, the
evidence is that the transition happened in Scotland some time in
the 15th or 16th centuries.
It also seems logical that the link between the operative and speculative sides of the Craft is sacred geometry.
The use of such geometric principles plays an obvious part of the design and construction of the architecture
(operative masonry), and study of the spiritual and esoteric meaning of the geometry leads to the realm of philosophy
(speculative masonry). Therefore, there would have been a time when the stonemasons' craft embodied both
operative and speculative aspects, with those who designed the buildings being aware of both the practical and
spiritual/symbolic side of design and construction. It is from the latter that Freemasonry in its modern form
would have evolved.
Many Masons' marks can be found in the fabric of the building, which is not surprising given the number of
stonemasons employed on the project. But the obvious symbolic design of the building, and of the carvings, attests
to a more speculative bias. Other parts of the building also point to a speculative masonic - i.e. Freemasonic -
intent. There is, for example, the legend attached to the Apprentice
Pillar, which echoes the Masonic legend of the murder of Hiram Abiff during the building of the Temple of
Solomon.
As Rosslyn was the personal project of Sir William St Clair, from conception and design to construction - all
the carvings having to be personally approved by him - his own knowledge and regard for the art of sacred geometry
is abundantly clear.
This conjecture is supported by the close link that Sir William's descendants had with Freemasonry. The St
Clairs were hereditary Grand Masters of Freemasonry in Scotland from at least the early 1600s. It is claimed that
this privilege was granted much further back - indeed, that it was given to Sir William, the chapel builder, by
James II of Scotland. This is not certain, as the original charters were said to have been destroyed in a fire in
Rosslyn Castle. However, the famous Schaw Statutes of 1602 - important documents in Masonic history drawn up by
James VI's Master of Works, William Schaw - also acknowledged and reinstated the hereditary position of the St
Clairs, noting that:
“…from age to age it has been observed among us that the Lairds of Rosslyn have been patrons and protectors
of us and our privileges, like as our predecessors have obeyed and acknowledged them as protectors and
patrons.”
After noting that acknowledgement of this right has been neglected in recent years, Schaw goes on to renew the
Masons' recognition of 'the said Sir William Sinclair now of Rosslyn and his heirs male our only patrons,
protectors and overseers'.
The Masons were also sufficiently convinced of the St Clair claim to issue new charters in 1630 confirming the
hereditary right.
The St Clairs of Rosslyn held this position until the last male of the line, another Sir William, voluntarily
gave it up in 1736. Sir William's renouncing of his family's right led to the creation of the Grand Lodge of
Scotland - which promptly elected him as its first Grand Master, even though he was not a Freemason. Sir William
had to be initiated at Kilwinning, the Mother Lodge of Scottish Freemasonry, before he could take up the position.
He was buried in Rosslyn Chapel with full Masonic honours in 1778.
Later, Rosslyn Chapel passed to the St Clair Erskine family, the Earls of Rosslyn and its current owners. In the
19th century, two Earls of Rosslyn, James St Clair Erskine (d.1837) and his grandson Francis St Clair Erskine
(d.1890), were elected Grand Master Masons of Scotland, demonstrating the continued ties between the St Clair
family, Rosslyn Chapel and Freemasonry. A 'Grand Masonic Fette' (fête), attended by over a thousand people, was
held at Rosslyn in 1870.
Francis St Clair Erskine, 4th Earl of Rosslyn, was elected in 1871, and the following year announced that he did
not wish to stand for re-election. In response, the Freemasons of Scotland drew up a petition, a scroll bearing
over 6,000 signatures, successfully pleading with him to reconsider. This shows the esteem that Scottish
Freemasonry holds for the St Clair family and Rosslyn Chapel. Francis St Clair Erskine was buried, at his own
request, in the grounds of Rosslyn Chapel.
