Tuesday, 8 September 2020
Hi, keep in touch with our projects through our Facebook page (put in Dorset Diggers and it will come up). During this difficult time we are still doing small projects (evaluations; test pitting; geophysics) ready for the time when we can return to excavations.

Grave Concerns
These six famous sites give us a
unique insight into the deep past and its peoples.
The Amesbury Archer gave us the
earliest example of gold use; the Wetwang Slack chariot burial helped to show
how these vehicles were made and used; The Spitalfield Roman has unique glass
wares; The Prittlewell tomb is on the cusp of pagan and Christian burial
rituals; The Sutton Hoo ship burial is the richest ever found in England; The
Mary Rose shipwreck opened a window on Tudor life at sea for the ordinary sailor.

Robert Boyle
Here is a short biography of the owner of Stalbridge House in the 17th century.
Robert Boyle FRS was born on 25th
January 1627 and died on 31st December 1691. He was an Anglo-Irish natural philosopher, chemist, physicist and inventor.
Boyle is largely
regarded today as the first modern chemist, and therefore one of the founders
of modern chemistry and one of the pioneers
of modern experimental scientific method.
He is best known
for Boyle's law, describing
the inversely proportional relationship between the absolute pressure and volume of a gas, if the
temperature is kept constant within a closed system. Among his
works, The Sceptical Chymist, is seen as
a cornerstone book in the field of chemistry. He was a devout and pious Anglican and is noted for
his writings in theology.
Boyle was born at Lismore
Castle, in County
Waterford, Ireland, the seventh son and fourteenth child of The 1st Earl of Cork ('the
Great Earl of Cork') and Catherine Fenton. Lord Cork, then known
simply as Richard Boyle, had arrived in Dublin from
England in 1588 during the Tudor plantations of Ireland and obtained
an appointment as a deputy escheator.
He had amassed enormous wealth and landholdings by the time Robert was born and
had been created Earl of Cork in October 1620. Catherine
Fenton, Countess of Cork,
was the daughter of Sir Geoffrey Fenton, the former Secretary of State for Ireland, who was
born in Dublin in 1539 and Alice Weston, the daughter of Robert Weston,
who was born in Lismore in 1541.
As a child, Boyle was fostered to
a local family, as were his elder brothers. Boyle received private tutoring
in Latin, Greek, and French and when he was eight years old, following the
death of his mother, he was sent to Eton College in
England. His father's friend, Sir Henry
Wotton, was then the provost of the college. After spending
over three years at Eton, Robert travelled abroad with a French tutor. They
visited Italy in 1641 and remained in Florence during
the winter of that year studying the "paradoxes of the great
star-gazer" Galileo Galilei, who was elderly but still
living in 1641.
Robert returned to England from continental Europe in mid-1644 with a keen
interest in scientific research. His father, Lord Cork, had died the
previous year and had left him the manor of Stalbridge in
Dorset as well as substantial estates in County
Limerick in Ireland. Robert then made his residence at Stalbridge House, between 1644 and 1652, and conducted
many experiments there. From that time, Robert devoted his life to scientific research
and soon took a prominent place in the band of enquirers, known as the "Invisible
College", who devoted themselves to the cultivation of the
"new philosophy". They met frequently in London, often at Gresham
College, and some of the members also had meetings at Oxford.
Having made several visits to his Irish estates beginning
in 1647, Robert moved to Ireland in 1652 but became frustrated at his inability
to make progress in his chemical work. In 1654, Boyle left Ireland for Oxford
to pursue his work more successfully. An inscription can be found on the wall
of University College, Oxford, the High Street at Oxford (now
the location of the Shelley
Memorial), marking the spot where Cross Hall stood until the early
19th century. It was here that Boyle rented rooms from the wealthy apothecary
who owned the Hall.
Reading in 1657 of Otto von
Guericke's air pump, he set himself, with the assistance of Robert Hooke,
to devise improvements in its construction, and with the result, the
"machina Boyleana" or "Pneumatical Engine", finished in
1659, he began a series of experiments on the properties of air. An
account of Boyle's work with the air pump was published in 1660 under the
title New Experiments Physico-Mechanical, Touching the Spring of the
Air, and its Effects.
Among the critics of the views put forward in this book
was a Jesuit, Francis Line (1595–1675)
and it was while answering his objections that Boyle made his first mention
of the law that the volume of a gas varies inversely
to the pressure of the gas, which among English-speaking people is usually
called Boyle's Law after his name. The person who originally formulated the
hypothesis was Henry Power in 1661. Boyle in 1662
included a reference to a paper written by Power, but mistakenly attributed it
to Richard Towneley. In continental Europe the
hypothesis is sometimes attributed to Edme Mariotte,
although he did not publish it until 1676 and was likely aware of Boyle's work
at the time.
In 1663 the Invisible College became The Royal
Society of London for Improving Natural Knowledge, and the charter
of incorporation granted by Charles II of England named Boyle a
member of the council. In 1680 he was elected president of the society, but
declined the honour from a scruple about oaths.
He made a "wish list" of 24 possible inventions
which included:
Ø
"the prolongation of life"
Ø
the "art of flying"
Ø
"perpetual light"
Ø
"making armour light and extremely hard"
Ø
"a ship to sail with all winds, and a ship
not to be sunk"
Ø
"practicable and certain way of finding
longitudes"
Ø
"potent drugs to alter or exalt
imagination, waking, memory and other functions and appease pain, procure
innocent sleep, harmless dreams, etc."
They are extraordinary because all but a few of the 24
have come true.
In 1668 he left Oxford for
London where he resided at the house of his elder sister Katherine Jones,
Lady Ranelagh, in Pall Mall. He experimented in
the laboratory she had in her home and attended her salon of intellectuals
interested in the sciences. The siblings maintained "a lifelong
intellectual partnership, where brother and sister shared medical remedies,
promoted each other’s scientific ideas, and edited each other’s
manuscripts." His contemporaries widely acknowledged Katherine's
influence on his work, but later historiographers dropped discussion of her
accomplishments and relationship to her brother from their histories.
In 1669 his health, never very strong, began to
fail seriously and he gradually withdrew from his public engagements, ceasing
his communications to the Royal Society. In the leisure thus gained he wished to "recruit his spirits,
range his papers", and prepare some important chemical investigations
which he proposed to leave "as a kind of Hermetic legacy to the studious
disciples of that art", but of which he did not make known the nature. His
health became still worse in 1691, and he died on 31 December that year, just
a week after the death of his sister, Katherine, in whose home he had lived and
with whom he had shared scientific pursuits for more than twenty years. Boyle
died from paralysis. He was buried in the churchyard of St Martin-in-the-Fields, his funeral
sermon being preached by his friend, Bishop Gilbert
Burnet. In his will, Boyle endowed a series of lectures that came to
be known as the Boyle Lecture.

'A Digger's Life: a load of rubbish'
The monthly meeting of the group saw Chris Tripp talk about how he got into archaeology and some of the sites he has dug over the last 30 years. From Bronze Age trackways, Roman warehouses and Iron Age settlements to Anglo-Saxon graves and Medieval cess pits. David Northam also talked through the possible project at Tumbledown Farm.
Saturday, 22 February 2020
Possible new site.
A new site has been looked at by members of the group at Weymouth. This area has been settled due to the river and access to the sea at this point. Good for trading and setting up mills. Roman and medieval features have been found around here.
Our Chairman David Northam showing us the site.
One area to investigate.
A second area to look at.
Some buildings that will be useful for storage and post excavation work.
Plans are afoot to do some geophysics surveying and the results will be published here soon.

Saw point
On his orders, Stalbridge House was taken down by the Earl of Uxbridge. This is the actual saw used to amputate the Earl of Uxbridge’s leg at the battle of Waterloo. Plus the bloody gloves used by his surgeon. The earl sounds like a cool customer, he merely remarked that the saw was ‘somewhat blunt’!

2020 AGM
