The history of Boyle

The Ó Baoighill of Donegal were one of the three great kindreds of Tír Chonaill, alongside the Ó Domhnaill and the Ó Gallchobhair, and ran the Boylagh peninsula on the western Donegal coast as a sub-lordship of the O'Donnell kingdom from the 11th century to the Plantation. The barony of Boylagh, west of the Glenties, still bears the family name. Cardinal Tomás Ó Fiaich, in his 20th-century scholarship, identified the Boylagh Boyles as among the surviving Gaelic clan structures in continuous local possession into the modern era, unusually, given the comprehensive Plantation displacement of most Donegal Gaelic surnames.

Richard Boyle, 1st Earl of Cork, the 'Great Earl of Cork', arrived in Munster in 1588 with twenty-seven pounds in his pocket and by his death in 1643 was the wealthiest man in Ireland, having acquired through the Munster Plantation an estate that ran to most of east Cork and west Waterford. His son Robert Boyle (1627–1691) was the founding figure of modern chemistry, Boyle's Law of gases, the founding of the Royal Society, the rejection of Aristotelian elemental theory. The Cork-Boyle line continues today as the Earls of Cork and Orrery, while the Donegal-Boyles remain heavily concentrated in the original Boylagh barony and across the wider Donegal-Sligo coast.

Stories of Boyle

Robert Boyle and The Sceptical Chymist
1661
In the spring of 1661, in the laboratory Robert Boyle had built behind the house of his sister Lady Ranelagh at Pall Mall in central London, Boyle, thirty-four years old, the seventh son of the Great Earl of Cork (Richard Boyle, the Anglo-Irish planter who had been the wealthiest man in Ireland at his 1643 death), former resident-experimenter at Oxford 1656–58 under the Cromwell government, founding member of the Royal Society (chartered in 1662, but operative as the Invisible College since 1645), completed the dialogue treatise The Sceptical Chymist: or Chymico-Physical Doubts and Paradoxes, touching the Experiments whereby vulgar Spagyrists are wont to endeavour to evince their salt, sulphur and mercury, to be the true Principles of Things, a octavo of about three hundred and eighty pages, published in London by F. Crooke in November 1661. The book, written in the dialogue form of four natural-philosophers in conversation, dismantled the Aristotelian four-element theory (earth, water, air, fire) and the Paracelsian three-principle theory (salt, sulphur, mercury) that had been the twin-foundation of European alchemy for two thousand years. In their place Boyle proposed the modern operational definition of a chemical element: a substance that cannot, by any laboratory technique then known, be reduced to a simpler form. The Sceptical Chymist is, by every careful judgment of the history-of-science (Marie Boas Hall, Lawrence Principe), the foundational text of modern Western chemistry.

Frequently asked

What does the surname Boyle mean?

Two distinct origins, both Anglicised as Boyle. The Gaelic Ó Baoighill, descendant of Baoigheall ('vain pledge'), was a 10th-century Donegal kindred, the third great northern dynasty alongside the O'Donnells and O'Dohertys.
