He was also instrumental in making a selection* which would, in general, be on the same level as my book The Exact Sciences in Antiquity. It may also provide a general background for my more technical History of Ancient Mathematical Astronomy and for my edition of Astronomi cal Cuneiform Texts. Several of these republished articles were written because I wanted to put to rest well-entrenched historical myths which could not withstand close scrutiny of the sources. Examples are the supposed astronomical origin of the Egyptian calendar (see [9]), the discovery of precession by the Babylonians [16], and the "simplification" of the Ptolemaic system in Copernicus' De Revolutionibus [40]. In all of my work I have striven to present as accurately as I could what the original sources reveal (which is often very different from the received view). Thus, in [32] discussion of the technical terminology illuminates the meaning of an ancient passage which has been frequently misused to support modern theories about ancient heliocentrism; in [33] an almost isolated instance reveals how Greek world-maps really looked; and in [43] the Alexandrian Easter computus, held in awe by many historians, is shown from Ethiopic sources to be based on very simple procedures."/><meta property="og:title" content="Astronomy and History Selected Essays"/><meta property="og:type" content="book"/><meta property="og:site_name" content="Google Books"/><meta property="og:image" content="https://books.google.com.sg/books/publisher/content?id=v1bmBwAAQBAJ&printsec=frontcover&img=1&zoom=1&edge=curl&imgtk=AFLRE71LP6EdtBD2i0kPcJy5aN4RmTThJ463tmuSKC5SKe_ym6usLJ5m_qs-2MQkBVBGuijW9A2rhtnGPsBhbmxq8_Lq0BP8mcNwUBXZOHIzQ1j0zWOoZ29zc1ntmyEIEmpwseVsVDyu"/><link rel="image_src" href="https://books.google.com.sg/books/publisher/content?id=v1bmBwAAQBAJ&printsec=frontcover&img=1&zoom=1&edge=curl&imgtk=AFLRE71LP6EdtBD2i0kPcJy5aN4RmTThJ463tmuSKC5SKe_ym6usLJ5m_qs-2MQkBVBGuijW9A2rhtnGPsBhbmxq8_Lq0BP8mcNwUBXZOHIzQ1j0zWOoZ29zc1ntmyEIEmpwseVsVDyu"/><script></script><style>#gbar,#guser{font-size:13px;padding-top:1px !important;}#gbar{height:22px}#guser{padding-bottom:7px !important;text-align:right}.gbh,.gbd{border-top:1px solid #c9d7f1;font-size:1px}.gbh{height:0;position:absolute;top:24px;width:100%}@media all{.gb1{height:22px;margin-right:.5em;vertical-align:top}#gbar{float:left}}a.gb1,a.gb4{text-decoration:underline !important}a.gb1,a.gb4{color:#00c !important}.gbi .gb4{color:#dd8e27 !important}.gbf .gb4{color:#900 !important} #gbar { padding:.3em .6em !important;}</style></head><body class=""><div id=gbar><nobr><a target=_blank class=gb1 href="https://www.google.com.sg/search?tab=pw">Search</a> <a target=_blank class=gb1 href="https://www.google.com.sg/imghp?hl=en&tab=pi">Images</a> <a target=_blank class=gb1 href="https://maps.google.com.sg/maps?hl=en&tab=pl">Maps</a> <a target=_blank class=gb1 href="https://play.google.com/?hl=en&tab=p8">Play</a> <a target=_blank class=gb1 href="https://www.youtube.com/?tab=p1">YouTube</a> <a target=_blank class=gb1 href="https://news.google.com/?tab=pn">News</a> <a target=_blank class=gb1 href="https://mail.google.com/mail/?tab=pm">Gmail</a> <a target=_blank class=gb1 href="https://drive.google.com/?tab=po">Drive</a> <a target=_blank class=gb1 style="text-decoration:none" href="https://www.google.com.sg/intl/en/about/products?tab=ph"><u>More</u> »</a></nobr></div><div id=guser width=100%><nobr><span id=gbn class=gbi></span><span id=gbf class=gbf></span><span id=gbe></span><a target=_top id=gb_70 href="https://www.google.com/accounts/Login?service=print&continue=https://books.google.com.sg/books%3Fid%3Dv1bmBwAAQBAJ%26printsec%3Dfrontcover%26dq%3Dsubject:%2522Science%2B/%2BSpace%2BScience%2B/%2BAstronomy%2522%26hl%3Den%26sa%3DX%26redir_esc%3Dy&hl=en&ec=GAZACg" class=gb4>Sign in</a></nobr></div><div class=gbh style=left:0></div><div class=gbh style=right:0></div><div role="alert" style="position: absolute; left: 0; right: 0;"><a href="https://books.google.com.sg/books?id=v1bmBwAAQBAJ&printsec=frontcover&dq=subject:%22Science+/+Space+Science+/+Astronomy%22&hl=en&sa=X&redir_esc=y&output=html_text" title="Screen reader users: click this link for accessible mode.

papers assembled here on a variety of topics in ancient and medieval astronomy was originally suggested by Noel Swerdlow of the University of Chicago. He was also instrumental in making a selection* which would, in general, be on the same level as my book The Exact Sciences in Antiquity. It may also provide a general background for my more technical History of Ancient Mathematical Astronomy and for my edition of Astronomi cal Cuneiform Texts. Several of these republished articles were written because I wanted to put to rest well-entrenched historical myths which could not withstand close scrutiny of the sources. Examples are the supposed astronomical origin of the Egyptian calendar (see [9]), the discovery of precession by the Babylonians [16], and the \"simplification\" of the Ptolemaic system in Copernicus' De Revolutionibus [40]. In all of my work I have striven to present as accurately as I could what the original sources reveal (which is often very different from the received view). Thus, in [32] discussion of the technical terminology illuminates the meaning of an ancient passage which has been frequently misused to support modern theories about ancient heliocentrism; in [33] an almost isolated instance reveals how Greek world-maps really looked; and in [43] the Alexandrian Easter computus, held in awe by many historians, is shown from Ethiopic sources to be based on very simple procedures.","my_library_url":"https://www.google.com/accounts/Login?service=print\u0026continue=https://books.google.com.sg/books%3Fop%3Dlibrary\u0026hl=en","is_magazine":false,"is_public_domain":false,"last_page":{"pid":"PA539","order":521,"title":"539"}},{"enableUserFeedbackUI":true,"pseudocontinuous":true,"is_cobrand":false,"sign_in_url":"https://www.google.com/accounts/Login?service=print\u0026continue=https://books.google.com.sg/books%3Fid%3Dv1bmBwAAQBAJ%26printsec%3Dfrontcover%26dq%3Dsubject:%2522Science%2B/%2BSpace%2BScience%2B/%2BAstronomy%2522%26hl%3Den%26sa%3DX%26redir_esc%3Dy\u0026hl=en","isEntityPageViewport":false,"showViewportOnboarding":false,"showViewportPlainTextOnboarding":false},{"page":[{"pid":"PP1","src":"https://books.google.com.sg/books/publisher/content?id=v1bmBwAAQBAJ\u0026pg=PP1\u0026img=1\u0026zoom=3\u0026hl=en\u0026sig=ACfU3U3dYPflmIH2Ozg_4Tif2C-tbPytcg","flags":32,"order":0,"uf":"https://books.google.com.sg/books_feedback?id=v1bmBwAAQBAJ\u0026spid=AFLRE72vcNIwdfRyeeY1zCMWP8iOpACab0iCyeUdVmZJiOKotAsW2-RgaMMM61njr4iIF_KhgKMg\u0026ftype=0"},{"pid":"PP3","src":"https://books.google.com.sg/books/publisher/content?id=v1bmBwAAQBAJ\u0026pg=PP3\u0026img=1\u0026zoom=3\u0026hl=en\u0026sig=ACfU3U0meJDPhub5-elbRo2QjPqIZvpUzA"},{"pid":"PP4","src":"https://books.google.com.sg/books/publisher/content?id=v1bmBwAAQBAJ\u0026pg=PP4\u0026img=1\u0026zoom=3\u0026hl=en\u0026sig=ACfU3U3-Pizc5xEgq-EtN0YhYObbAlp5Sg"},{"pid":"PP7","src":"https://books.google.com.sg/books/publisher/content?id=v1bmBwAAQBAJ\u0026pg=PP7\u0026img=1\u0026zoom=3\u0026hl=en\u0026sig=ACfU3U1SNvZMkOGc0qHVSGyL_YWXDdDvUg"}]},null,null,{});</script></div></div></div><script>(function() {var href = window.location.href;if (href.indexOf('?') !== -1) {var parameters = href.split('?')[1].split('&');for (var i = 0; i < parameters.length; i++) {var param = parameters[i].split('=');if (param[0] == 'focus') {var elem = document.getElementById(param[1]);if (elem) {elem.focus();}}}}})();</script>
