Rated 5 out of 5 by from Great Course This is a great course if you like history the way I do. It covers ancient beliefs and explains away some myths about ancient beliefs. It also cover the progression of from ancient beliefs to start of modern astronomy. I really enjoyed it.

Rated 1 out of 5 by from The Remarkable Science of Ancient Astronomy Clearly not up to the quality of Teaching Company greats such as Philip Cary, William Kloss and Michael Starbird. The staging was glitzy, the presentation style of the professor was unpleasant and the course seemed to be stuck on denouncing the evil popularizers of ancient astronomy. Providing viewers with an understanding of the basic celestial mechanics that ancient astronomers must have understood would have been good starting point.

Rated 5 out of 5 by from exceeded my expectations I was amazed to learn how far the ancients had gone in the observation and analysis of astronomical phenomena. Also I had no idea of the diversity of the various calendars used by the various ancient cultures. The explanation of the concepts involved were easy to follow thanks to the excellent presentation and graphics.

Rated 3 out of 5 by from I found this course to be mildly interesting, it would be more so if I were a history buff. If the student is studying ancient history, related topics in ancient astronomy, and the ancient world in general, this course is for you. If you are studying current topics in astronomy you also might find this course useful. It can be a useful companion piece to other courses offered by the Teaching Company such as A Visual Guide to the Universe, and Our Night Sky. misconceptions.

Rated 2 out of 5 by from Condescending This lecture series could be mostly summed up with “Silly ancients, so superstitious” with some “Silly moderns, still superstitious” thrown in from time to time. The lecturer does allow the Greek natural philosophers some credit for their work, but points out they were all wrong anyway once he covers the discoveries of the renaissance. I imagine the lecturer has gotten tired of some of the more out-there ideas about ancient astronomy that circle the internet but when the course is titled “The Remarkable Science of Ancient Astronomy” I would think that some recognition of the work done was in order no matter how misguided the reasoning behind it was considered. The final lecture was the first time the lecturer show any signs of acknowledging the remarkableness that the course was supposed to be about. However, if you can get past the condescension there are some very interesting pieces of information to be gleaned that make it mostly worth it – just make sure you buy it on sale.

Rated 4 out of 5 by from Great course I have now taken 3 great courses from this company. I rank this course tied for second, with Prof. Leo Damrosch's "Gibbons' Decline and Fall of the Roman Empire." Prof. Bradley Schaeffer gives a very wide ranging, world-class presentation, with special emphasis on the Greeks, late in the course.. I can't think of anything not to like. You might feel a bit bogged down by some of the first dozen lectures (maybe) but when he gets to the Greeks and Europeans he really shines. He also covers the early astronomy,( actually mostly astrology), of China, the Mayans, the early Brits, the Australian Aborigines, the Hindus, and the Middle East, the Europeans, and the Polynesians as well, so every episode brings something different and he proceeds at a fast pace. He also puts extra emphasis on a new book's interpretation of the Bible's "Star In the East" seen by the 3 wise men.

Rated 4 out of 5 by from Good content and reasonably good presentation I hesitated about buying this lecture series because a couple of other reviews said the instructor's presentation was bad. I disagree. He's no master showman, but his presentation is perfectly all right. The subject is interesting but not terribly visual, so he mostly has to stand and talk. That's not easy to do without seeming a little dry. If you're interested in the content and don't need lots of gee-whiz graphical entertainment to hold your attention, this is a fine lecture series. I recommend it.

Rated 3 out of 5 by from Save your money Notwithstanding the title of this course, there is very little "science" and lots of supposition and speculation. Given the subject matter, I guess that is to be expected. But the presentation is sorely lacking, as Prof. Schaeffer has TERRIBLE cadence; he struggles with reading the teleprompter in a conversational manner, and often adds phrases and clauses after he has already ended a sentence (or so a listener would assume). Plus, the ONLY correct pronunciation of the word "height" is "hite," not "hithe" -- there is only one "h," and it is at the beginning, not the end.

Rated 4 out of 5 by from I am a history buff and lately have moved more into astronomy courses. This is my 3rd one. Also when we travel we try to visit observatories around the country. This helps my understanding of the wonders of the universe. Also, it gives insights into the development of "science" over the centuries.

Rated 2 out of 5 by from Archaeoastronomy - NOT! In a word - disappointing. I chose this course based on a lifelong interest in astronomy and his mentions of archaeoastronomy by Professor Edwin Barnhart in his GC Lost Worlds of South America and Maya to Aztec: Ancient Mesoamerica Revealed courses. But, I quickly discovered I got tricked by the course description in the catalog (and, admittedly, the courses 'giveaway' price which I now understand). I concur with BGZRedux that this course might be better titled How The Ancient WESTERN World Saw the Stars. Or, better yet, Astrohistory of Ancient Mesopotamia and the Eastern Mediterranean. It's certainly not a world view. Just as problematic for me was the mish-mash nature of the presentation. I'm the proud owner of over thirty GC DVD courses focused primarily on ancient history. Only once despite a variety of 'unique' presentation styles and approaches have I returned a course for 'unwatchability'; this was a close call on that count. Two of my basic criteria are that each lecture should, at least, address the subject of its title and NOT subject me to more repetition than necessary to provide a transition from the previous lecture. This course fails on both counts. Then, there is Professor Schaefer himself. I get that he's a recognized history of astronomy expert. I also now get that he's NOT an ancient historian (one example - calling the Lydians and the Medes (he calls them 'Medees') Greeks). He's also a very difficult to watch, perpatetic speaker/presenter with distracting gestures, too many mispronunciations, and a seeming inability to read back words that he, presumably, wrote with the proper inflection and pacing from a teleprompter. Additionally - as noted by other reviewers - he assumes too much innate knowledge of his audience regarding technical terms and references such as to the pin-and-slot gear. At times, he's bewilderingly technical and at others almost insultingly simplistic. In the interest of fairness, I have to give Professor Schaefer credit for the most comprehensive explanation of the Antikythera Mechanism I've ever heard and for enlightening me on the importance of astrology to the ancients. Would that there'd been more to praise. Pretty hard to believe that neither the Chinese, Mayans, Asian Indians, or Aztecs didn't merit more than about five minutes mention in only two of the lectures. Far less than Professor Schaefer allotted to pat himself on the back for his own research.

Rated 5 out of 5 by from Excellent course for learning what amazing things the "ancients" knew about astronomy. I had often wondered how they obtained their knowledge, and this course helped to show me. Excellent professor, as usual for The Great Courses!

Rated 5 out of 5 by from Nice general introduction I bought this a couple of weeks ago. I am most of the way through and have enjoyed the course. The instructor does a good job making complicated, and sometimes convoluted clear. He separates good science from bad and explains the differences. I enjoyed hearing him talk about his own research, as well. I especially appreciated his visuals. I've taken several of these courses and sometimes I feel there are not enough visual aids or that the aids were more like illustrations than actual teaching tools. That was not the case with these.

Rated 5 out of 5 by from Truly Remarkable I came to this course with little knowledge of astronomy, let alone how it developed in the ancient world. Professor Schaefer does an excellent job in making the advances easily understandable. I am impressed with his fine and measured delivery and the many graphics and illustrations he employs. While this course takes in a considerable time-period and geographical extent, I especially appreciate Professor Schaefer’s discussion of astronomy’s relationship to astrology, the lectures on the Christian Star of Bethlehem and the Islamic calendar, and astronomical developments in non-Western settings. Most of all, however, I came away with an even greater appreciation of the Greeks’ achievement. An example is that though I had been familiar with the name of Ptolemy, until this course I had only a hazy idea about his significance. Now I know a great deal more, not only about his preeminence, but also about several other very significant ancient Greek astronomers. Even more fascinating are Professor Schaefer’s two lectures on the ancient Greeks’ Antikythera mechanism. This is an analogue computer that could predict astronomical positions, eclipses, etc., the “…highest pinnacle of ancient astronomy” (Course Guidebook, Page 184), and which has come to be better understood in only in recent years through such advances as X-Ray Tomography. For one who has a keen interest in ancient Greece, this course deepens my understanding and appreciation. While one might assume that these lectures about astronomy in the ancient world are just so much dead and gone ancient history, Professor Schaefer ends the course showing how the transition to modern astronomy took place, and how the observations of ancient astronomers contributed to modern astrophysics. This makes a very interesting and informative course. The 266-page course guide is one of the best I have seen thus far in all the TC courses I have taken. The lecture summaries are great and include many illustrations from the video, a list of constellations, a timeline, and an extensive annotated bibliography

Rated 5 out of 5 by from Fills in Gaps I teach introductory astronomy at the university level. This course fills in many gaps in the history of astronomy left out of modern astronomy textbooks. I greatly appreciate the depth to which these lectures went into the subject. I think it is important to know how our current understanding came about. This course does just that. It will help me teach my astronomy course in the future.

Rated 3 out of 5 by from Unusual content, visually disappointing I recommend this course for those interested in the ancient world, calendars, the New Testament, Hajj, astrology, astronomy, or history of science. The content is unusual, sound and informative. It explodes common misconceptions. Like many Teaching Company courses, however, this one is tedious visually. It simulates a classroom (not a great idea in itself) and focuses the camera much too often, and much too long, on the professor who is reading from a teleprompter system while trying to make the hands move right. It's unnatural. I would much prefer to watch slides and film clips while listening to smart narration. The professor should be seen briefly, perhaps at transition points in the lecture as well as in the introduction and summation. Specialists in classroom visuals should be consulted to refresh the presentation style. However, one must appreciate the value for the cost. The Teaching Company brings courses rich in content to market at bargain prices.

Rated 4 out of 5 by from Interesting Parts of this course were very interesting but the discussion of some of the technical details - on the astrolabe, and some of the astronomical models could have used some more graphics to make it clearer how these were supposed to work.

Rated 4 out of 5 by from good but slanted overview I am a professional astronomer. I would say that this course is a good overview of many of the important topics in ancient astronomy, including navigation, calendars, alignments with the solstices (at Stonehenge and other places, and the theory he presents about Stonehenge is up-to-date), etc.. Schaefer's delivery is sometimes stilted, but it's fine once you get used to him, and he even gets in a few good jokes and annecdotes (love the story about the Red River meteorite). The visualizations done by the Teaching Company are generally very good and illustrative. I haven't looked at the course guide yet. I think the greatest value added in this course is hearing about Schaefer's practical naked eye tests of ancient astronomy, such as testing the visibility of constellations described in MUL.APIN or coming up with a model for the young crescent moon visibility. Real world tests like this are extremely valuable in archeology, and not many have been done in archeoastronomy by someone with chops in science and statistics like this. Indeed, I would have liked to have seen more evidence for some of theories he supports or dismisses (such as the Kate Spence Pyramids dating) without much comment. However, Schaefer's bias as a Christian is apparent when he talks about attempting to date the crucifixion or in his full lecture on the Michael Molnar astrological explanation for the Star of Bethlehem (which is *not* the most widely accepted explanation for the story). If this is the right explanation, then this would seem to provide strong evidence that astrology works! The Chaldeans saw the signs for the birth of a great king in Judeah, headed out, and they found Jesus! So either astrology works, or that was a meaningless coincidence, included in Matthew because... ? (For a better SOB explanation, I recommend the new book by Aaron Michael Adair.)

Rated 5 out of 5 by from Great story teller This is basically a history course telling how astronomy evolved from its earliest days. Dr. Schaeffer does a sterling job. He gives an update (2012) on the research of the Antikythera Mechanism plus he devotes 2 whole lectures to it which was the high point for me.

Rated 3 out of 5 by from Good Intro to Ancient Astronomy This is a fine general introduction to the topic, though you may already be familiar with much of this material if you watch science and history shows on TV. Dr. Schaefer misses no opportunity to disparage astrology, which I'll admit made me flinch. I did post-graduate research in South Asian culture, and was actually astonished at the sophistication of ancient Indian astrological traditions, for example how myths are used to code astronomical information (each Vedic deity is associated with a particular star, such as Vishnu with Altair). In Hindu cosmology, sidereal astrology makes a certain amount of sense as all events in time and space are bound together in consciousness. I learned to be less quick to mock non-Western traditions, and to be more to respectful of the perspectives of other cultures.

Rated 3 out of 5 by from Obvious questions left unaddressed I'm only through the first disk but there are some major issues that I'm surprised were not discussed. The lesson on the astronomy of the great pyramids did not discuss the alignment of pyramids with those in Orion's belt, which is discussed at length in nearly all Discovery Channel-type shows. There is also a huge block of evidence the pyramids were built over 12,000 years ago and celestial evidence is used as the proof - this discussion was also conspicuously absent. Perhaps the rest of the lessons will be more enjoyable but so far it feels like the book "The Golden Ratio" which basically says we modern people are smart and those old people didn't know much.
