Britain thus acquired her first Astronomer Royal. , the final volume appearing in 2002, a work that by its very nature was a milestone in studies of the early years of the Royal Observatory, Greenwich Willmoth comments of Robert Hooke that he was unlikely to approve any longitude claim that rivalled his own (Willmoth 1993: 178) whilst of Bonds method, Pell himself had Found it ignorant and groundless and fals but resolved to speak favourably of it (Hooke The manuscript by Johannes de Sacro Bosco or Sacrobosco De sphaera mundi, mostly relating to the celestial spheres but also making clear Sacroboscos view that the Earth was a globe, was written ca. . His interest was benevolently exploited by courtiers and individuals to carry forward their own plans to found a national observatory in Britain where a skilled astronomer might be employed to make observations of and catalogue celestial objects for the purpose of discovering the longitude for the benefit of navigation. , though as the Society was not meeting and with its President, Lord Brouncker, unwell, he feared that they would decline to proceed. Hooke makes several notes about meeting Flamsteed on his second visit to the capital in 1674, the last being on 8th August (Hooke 1935: 112, 114116).

Journal for the History of Astronomy, xiv: 2, 40. van Helden, A., 1996. In 1884, a delegation of international representatives convened in Washington, D.C. to recommend that Earth's prime meridian (the north-south line marking zero degrees longitude) should pass through the Airy Transit Circle at the Royal Observatory in Greenwich, England. , of course; he continued, again with Bailys footnote: It was easy to perceive, from these demands, that the Sieur understood not that the best lunar tables of determining the longitude at sea (Bryden 1993: 1733). It was unambiguously stated to Chicheley in the 22nd June warrant that the Kings Will and pleasure is that according to such plot and designe as shall be given you by our trusty and well beloved Sir Christopher Wren, which had also specified that the location was upon the highest ground at or neare the place where the Castle stood In practice this meant at a maximum budget of 500 for the whole construction that the castles footings were recycled anew to serve for the observatory, to save the expense of relaying the foundations (Baily 1835: 39). Then as now the logic of state funding remains an arcane and sometimes dubious mystery to we, the humble citizenry. In 1674,Charles II appointed a Royal Commission to look into how the country could realise this potential.

Though this concept had contemporary currency, it is sufficient to observe that by the period of interest to us, the early 1670s, the problem could be posed with precision, but a precise solution to finding the longitude at sea eluded astronomers and navigators of the late 17th century. Annals of Science, 42 (1985), 6, 547548. State Papers Domestic, pp.2728. The Greenwich Meridian was chosen to be the Prime Meridian of the World in 1884. of finding longitude. Contrivd for Flamsteed to see the Bishop of Sarum, Seth Ward, during his visit. This is not to say there were no other instrumental contributions. Saunders comments that there are in fact ten engravings in the series as there are two copies of Howse Plate XI, Facies Sextantis Anterior. Its primary contributions were in practical astronomynavigation, timekeeping, determination of star positions, and almanac publication. The site was handed over to the National Maritime Museum (NMM) piecemeal and opened to the public. Positional circles joining in the north and south points of the observers horizon are laid through distances of 30 degrees on the celestial equator, thus giving unequal sections of the ecliptic. In more concrete terms by the middle of 1662 and in the spring of 1663 he had issued charters to The Royal Society For the text Oestmann refers to see the illustration of the Johann Hecker preface at http://www.astrology-and-science.com/h-flam2.htm, which is taken without attribution from the original in Flamsteeds hand (A28) described by Willmoth as Hecker his large Ephemeris , at Mr. Rookes chamber at Gresham College; in the vacation at Mr. Balls chamber in the Temple. 50, K). In a MS paper by Flamsteed, entitled Notes to my state of the Observatory, mentioned in page 5, it is stated (page 51) that this lady was the Duchess of Portsmouth between 16361657 (Forbes 1976: 8). Flamsteed, for all his faults, knew a good man when he met one. The expansion in authoritative post-war scholarship on all aspects of the early history of the Royal Observatory, which became an even greater expansion after the tercentenary in 1975, is reflected in the Reference section of this chapter and the following chapter (see Section 2.14). The source for the information on the operation of the Equatorial Sextant Nautical Almanac Offices and NASA We know that Flamsteed wrote to Moore on 20th February 1673, when he referred to the gift of the Towneley micrometer, and had a reply a year later, on 7th March 1674, with Moores apology for his lapse in writing due to the excuse of our much busines in the WarrFootnote 12 (Forbes et al. The Place illustrations certainly give a strong flavour of how things were there in the late 1670s. Royal Observatory - Wikipedia Then a short time later Frances Willmoth, the daughter of a Royal Greenwich Observatory scientist living in Sussex, began reading for an MPhil and subsequently a PhD at the University of Cambridge Though he gave his teachings in Paris, Sacrobosco may have been English John of Holy Wood though the evidence for this, even if later in the medieval period, seems to be by assertion or simply appellation. John Hill was Purveyor for Measuring Works at the Ordnance Office, see Tomlinson (1979: 236). that he borrowed from the Royal Society, and Flamsteed brought his own three feet quadrant A few days before, on 27th June/7th July 1675, Hooke had been up at 3:00am to see the beginning of the total eclipse of the Moon that morning http://astro.ukho MS.2972. comes from the Ars Poetica of the Roman poet Horace (65BC8BC). at Garaways.

Consequently the north-south axis of the familiar Christopher Wren/Robert Hooke building at Greenwich, now known as Flamsteed Flamsteed assured Moore that for the futur my opinion of him shall be much more charitable. William Viscount Brouncker, a mathematician, was the first president of the Royal Society, 1662 to 1677. The bottom-line cost of 520 to build, if not equip, the Greenwich Observatory, which to us today appears a derisorily small amount, was then a significant sum to commit to a project that guaranteed no successful outcome. Notes and Records of the Royal Society of London, 47 (1) January, 1731. Mural Arc at over 200 (Birks 1999: 161), so approximately 40% of the cost of the Wren/Hooke Royal Observatory. MS.RGO Flamsteeds salary was just 100 per year, but after his preferment in 1684 this was now augmented by the glebe and tithes of the living of Burstow See also Howse (1980: 32, 237, endnote 29).

Within the Room were moveable instruments, a three-feet quadrant of navigation goes back to the committee set up not two years after its foundation, consisting of Brouncker, Moray, and Henry Bond, and only eighteen months before the events Brouncker and Moray, Hooke, Morland, Pell, Titus, Ward, and Wren, with Charles Scarborough and Jonas Moore had been requested by Charles to assess this method John Flamsteeds horoscope for laying the groundwork of Greenwich astronomy and astrology [in German]. Journal Book: minutes of ordinary meetings of the Royal Society. MS.RGO MS.RGO s design in some way, and Hooke was ever prone to take umbrage, but quite how Flamsteeds arrogance was manifested we know not; perhaps he again said he did not claim to have improved on Newtons telescope? A CENTURY AT ZERO LONGITUDE - The New York Times Though the building work for the Observatory took a year or so and seems to have proceeded with little mishap, there was evidently many a slip in the provision of the most accurate observational equipment for Greenwich. from a number of contemporary accounts,Footnote 6 which have, from the mid-1970s and the tercentenary of the Royal Observatorys foundation, for 30years or so attracted wider scholarly interest (see Section 2.14). Forbess conclusion is that Thus St Pierre was fully justified in being sceptical of the authenticity of these data, and in being puzzled as to how, when and where they had been acquired (Forbes 1976: 47). After late Aprils letters written to Pell we therefore reach the point in the summer of 1675 where the building of Charless observatory was directed in his Warrant: Whereas in order to the finding out of the longitude [of] places for perfecteing Navigation and Astronomy Wee have resolved to build a small observatorie within our Parke at Greenwich upon the highest ground at or neare the place where the Castle stood with lodging-roomes for our Astronomicall Observator and assistant. Willmoth Bury St Edmunds, The Boydell Press. Derek Howse devoted a whole edition to the engravings, all being reproduced in detail within (Howse 1975b, Hake 19211922: 3969, D2). A total of 520.45 was spent on construction, with costs being kept down by using recycled materials. et al. Indeed on 22nd April, the day after achieving that invitation, Hooke and presumably, as he is mentioned in the diary entry, Moore too visited Bishop Ward (Hooke 1935: 98). , Mr Bruce, Sir Robert Moray, Sir Paule Neile, Dr Wilkins, Dr Goddard, Dr Petty, Mr Ball, Mr Rooke, Mr Wren, Mr Hill.

In 1642, being then called Greenwich Castle, it was thought of so much consequence, as a place of strength, that immediate steps were ordered to be taken for securing it. s Gresham College meeting of the 18th February, Flamsteed taking with him letters that were his first written responses to the St Pierre method Certainly the 1975 tercentenary of the foundation at Greenwich stimulated a good number of publications, very important figures amongst the authors being Eric Forbes and Derek Howse, with a significant contribution coming from William McCrea, the latters work being aimed at an informed general audience (Flamsteed 1975, Forbes 1975a, b and Forbes 1976; Howse 1975a, Howse 1975b; McCrea 1975). Our Will and pleasure is that according to such plot and designe as shall be given you by our trusty and well beloved Sir Christopher Wren knight, our surveyor Generall, of the place and scite of the said Observatori(e) you cause the same to be fenced in built and finished with all convenient speed, by such artificers and Workemen as you shall appoint thereto and that you give order unto our Treasurer of the Ordnance for the paying of such materialls and workemen as shall be used and employed therein out of such monyes as shall come to your hands for old and decayd powder, which hath or shall be sold by Our order of the 1st of January last.

However, Flamsteeds best instrument only became available in 1689. By the 30th June he wrote to Moore that I shall soone be aweary of Cambridge and that the company of an anatomist in the college made my being here onely not intolerable; notwithstanding such a bleak prospect, the night he wrote those words he also told Moore he intended to set up his 14ft. telescope and, if it were clear, to begin observations (Forbes et al. See Forbes, et al. For a modern analysis of the horoscope see Gnther Oestmann (Oestmann 2002), his abstract reads: The paper deals with the astronomical and astrological contents of a horoscope cast by John Flamsteed in 1675 for the foundation of Greenwich Observatory. His salary of 100 per annum was to be paid as a charge under the Board of Ordnance, where of course Thomas Chicheley (16141699) and Jonas Moore were, respectively, Master-General and Surveyor-General.
