MOON VERSUS MACHINE

Compared with that of Banks, Mr. Green’s equipment was comparatively modest. On May 5th, 1768, at a meeting of Council of the Royal Society it was resolved that the instruments for the use of the Observers of the South Latitudes be the following:

Two [2] reflecting telescopes of two [2] foot focus…[1] brass Hadley’s sextant, [1] barometer bespoke of Mr Ramsden, [1] Journeyman’s Clock bespoke by Mr Skelton, two [2] Thermometers of Mr Bird, [1] Stand for Bird’s Quadrant, [1] dipping needle bespoke by Mr Ramsden’. H.C. Cameron, Sir Joseph Banks, Angus and Robertson, Sydney, 1966

Who was Mr. Green? Charles Green was former Assistant to James Bradley and Nathaniel Bliss, Astronomer Royals of Greenwich Observatory. He was engaged by the Royal Society to represent them and assist Lieutenant James Cook RN observe and record the Transit of Venus due to take place at Tahiti on 3rd June 1769.

Why was Harrison’s marine chronometer ‘H-4 bolted to a window seat in the [Greenwich] Observatory’ when Green set off for Tahiti aboard HMS Endeavour with Lieutenant James Cook. See: Captain Cook, John Harrison, Charles Green – Three Yorkshire Men Walked Into A Bar

‘H-4 [was] bolted to a window seat in the Observatory’.  Dava Sobel, Longitude, Fourth Estate, London, 1998

No doubt H-4 sat under the watchful eye of Rev. Nevil Maskelyne. Britain’s fifth Astronomer Royal. Maskelyne had been elected to that high post in 1765 on the death of Rev. Nathaniel Bliss. Maskelyne held a conservative stranglehold over the position until 1811.

‘How elaborate his [Joseph Banks] preparations were we may gather from a letter from John Ellis, Fellow Royal Society to Linneaus: ‘No people ever went to sea better fitted out for the purpose of Natural History”. John Ellis, cited H.C. Cameron, Sir Joseph Banks, Angus and Robertson, Sydney 1966

Lieutenant James Cook RN was charged, at the behest of England’s prestigious Royal Society, with conveying Joseph Banks and his party of ten (10) to Tahiti and there observe the Transit of Venus.

‘The Transit was more than just an astronomical curio, it was the key to a wealth of information about the universe, information that would be seized upon by the intensely curious men of science who characterised the age’. Vanessa Collingridge, Captain Cook, The Life, Death and Legacy of History’s Greatest Explorer, Random House, London, 2003

Tahiti in the southern hemisphere was a logical choice from where to observe and record the event if, as predicted by Edmond Halley, planet Venus did indeed pass across the face of the sun on 3 June 1769.

Endeavour’s voyage to Tahiti  might best be described as a ‘piggy-back’ joint venture. The Royal Society did send ‘men of science’ – William Wales and John Dymond – to the icy north to observe the Transit from Hudson’s Bay. The institution however could not alone finance Tahiti.

The Admiralty agreed to supply a ship, its commander and crew. In truth the Transit was a smoke-screen. Government intended to extend the Tahiti voyage.

Following the Transit, Cook’s ‘secret Admiralty orders’ sent Endeavour south to search ‘down under’ for the fabled Great South Land. Of  Bank’s party of ten (10) botanists, naturalists, artists and servants only four (4) – including Banks himself – survived the second phase of the voyage.

THE BACK STORY

Edmond Halley’s imagination had been fired on observing;‘a more common transit of Mercury from St Helena a century earlier in 1677’. Dava Sobel. ibid.

As early as 1716 Halley of comet fame postulated there would be two (2) such transits in the decade 1760, furthermore Halley predicted another century would pass before such a phenomenon would be seen again.

The reigns of three (3) English Kings –  Charles I (1625-1649) Charles II (1660-1685) and George III (1760-1820) intersect here.

1649 – 30 January, London: In 1649 King Charles I of England and Scotland was beheaded in Whitehall.

1649 – 19 May, Westminster: An Act of Parliament passed in May 1649 declared England a Commonwealth of nations – England Ireland and Scotland.

1653: Oliver Cromwell was installed as Lord Protector of the Commonwealth in 1653 a position he held until his death in 1658.

‘During his five-year reign, Oliver Cromwell had done what no other ruler in English history had done. He had secured the British Isles as a single state including Scotland and Ireland, and secured England’s future as a colonial trading empire.

 Above all he had built an English navy which in number and quality of ships, in its finances and administration, in its officers and men, and in its global reach was superior to any in the world’. Arthur Herman, To Rule The Waves, Houghton & Stoughton, London, 2005

1655: Jews, driven out of England by King Edward I in 1290, were formally readmitted during Cromwell’s rule to invigorate the Commonwealth’s flagging economy.

1658 – 3 September: Oliver Cromwell ‘mighty general [of] The Parliamentary Revolution who, in 1649 drove the beheading of Charles I, died of natural causes in September 1658. Cromwell’s own macabre dead-heading had yet to come.

Heir Apparent Prince Charles who, following his father’s beheading, fled to the continent. He lived in exile for nine (9) years firstly in France then, when the French sided with Cromwell, moved to the Netherlands.

1659 – 60:  On Oliver Cromwell’s death and, the failure of his son Richard to maintain Britain as a Commonwealth under The Protectorate, Prince Charles was invited to return to England and restore the Monarchy.

1660 – February, Holland: Samuel Pepys the celebrated diarist sailed to Holland with his uncle Edward Montague. Both ardent Royalists their mission was to retrieve the now thirty (30) year old Prince Charles.

1660: Antagonist and protagonist passed each other on the high seas, Richard Cromwell fleeing to a long exile in France, Prince Charles on his way to a triumphant entry into London.

1660 – May, Westminster: Charles with all ‘pomp and circumstance’ was crowned King Charles II of England and Scotland the land of his father’s birth.

Captain Robert Holmes who commanded the retrieval voyage went on to snatch New York (New Amsterdam) from the Dutch.

Montague, later first Earl of Sandwich, made marines an integral arm of the Naval Service. He was killed in a sea battle during the third Anglo-Dutch war.

Samuel Pepys is regarded as the father of Britain’s modern Royal Navy. According to Arthur Herman, To Rule the Waves, Pepys was ‘a skilled bureaucrat who could subdue critics with a relentless barrage of facts and figures’.

Richard Cromwell returned to England in secret and lived there as Richard Clarke until his death in 1712.

France, like England a maritime nation, had particular interest in the ‘The Art of Navigation’. In the 1660s King Louis XIV established the French Royal Observatory and Royal Academy of Sciences.

King Charles II, having spent considerable time in France, was well aware the French king continued to pour immense resources into the sciences.

1674: After the turmoil of Civil War and Cromwell’s Protectorate, the King was forced to play catch-up. To that end in 1674 he commissioned Christopher Wren the celebrated architect and astronomer plan a Royal Observatory.

Wren, fresh from designing the rebuild of St Paul’s Cathedral destroyed in the 1666 Great Fire of London, selected Greenwich Castle to be perfectly placed ‘for perfecting the Art of Navigation’.

Although the castle had been destroyed by Cromwell’s Model Army during the Civil War its solid foundations were intact. As with St. Paul’s in 1666 on the Observatory build, Wren relied on Robert Hooke’s expertise in the science of surveying.

1675: Construction of the Observatory began in July 1675 and remarkably in just one (1) year the Royal Greenwich Observatory was up and running.

1676: The King appointed Rev. John Flamsteed Britain’s first Astronomer Royal. He held that exalted position for forty-five (45) years until his death in 1720.

However Flamsteed’s long tenure was plagued by bitter controversy centred on his life’s work – Lunar Tables and Star Catalog – noting upwards of 3000 stars. Flamsteed, a perfectionist, refused to publish until absolutely satisfied of the accuracy of his Tables on which so many lives depended.

Two (2) personages whose stars remain luminous in today’s world of science – Sir Isaac Newton and Edmond Halley purloined Flamsteed’s writings and un-attributed had them printed and published.

Not until after his death (1720) were Flamsteed’s writings published under his own name. To add insult to injury, although Flamsteed could not have known, King George I appointed Halley to succeed him as Astronomer Royal.

 1720–42: Halley’s tenure of twenty-two (22) years was coloured by continuing accusations over the double-dealing and plagiarism linked to his and Newton’s nefarious dealings with Flamsteed.

These two (2) men faced the same problem as Flamsteed. How to accurately determine longitude when ships were at sea beyond sight of land?

Although half a century earlier Wren’s collaborator Robert Hooke (1635-1703) the celebrated polymath of his day, held the clock offered ‘a certain way of determining longitude’ both Newton and Halley hitched their wagon to the stars.

Hooke spent much energy in an attempt to conquer time-keeping. As early as 1655 he introduced English clock-makers to an improved pendulum. In a further effort to make a time-keeper that could achieve the Holy Grail, determining longitude at sea, Hooke produced the ‘balance spring’.

In  Paris Christiaan Huygens of Holland, now in the employ of King Louis XIV, was making similar progress.

‘With his marine clocks, John Harrison tested the waters of space-time….He wrested the world’s whereabouts from the stars, and locked the secret in a pocket-watch’. Dava Sobel. ibid.

The fifth Astronomer Royal Rev. Nevil Maskelyne appointed in 1765 persecuted John Harrison the carpenter- artisan whose marine chronometer, H-I, had shown as early as 1736-37 on a voyage to Lisbon in HMS Centurian, capable of determining a ship’s position in relation to the land. See: Malicious Maskelyne  and  Lotto and Longitude 

‘John Harrison the man who solved the problem of longitude in 1759’. Peter Ackroyd, Revolution.

Is it not ironic in 1768, as HMS Endeavour was being made ready for Tahiti and into the southern oceans, the robust jealousies and in-fighting among scientists of Flamsteed and Newton’s day were still centred on Lunar Tables and Star Catalog versus a reliable time-keeper?
