    *My purpose today is to show three facts -- and by "show" I mean to prove them in such a way that you can reproduce the proof and see for yourself that what I assert is true (or, of course, prove it is NOT true if you think you can!). I will include links to high resolution images in the web version of this talk that you can download for that purpose.

    The facts are: First, The Lascaux Cave Bull painting shown here is an accurate star chart painted around 15,000 BC. - This is the oldest existing star chart by many thousands of years. Second, internal evidence in this painting indicate that the star chart must be older than 13,200 BC and younger than 17,000 BC. This gives solid boundaries on the possible times that this painting was made, totally apart from any other dating method. Third, but for God's Providence, this star chart would not be known today, and at best it would have faded into the mists of myth and folk lore.=====

    A full resolution image of this painting is at:http://www.free-hdwallpapers.com/wallpapers/architecture/1075.jpg.*This is a sky chart generated by the program Cartes du Ciel -- an excellent, free sky chart program. Actually this is the "negative" of a sky chart: the colors are inverted because I find it much easier to work with the inverted images.The "river" in the middle is the Milky Way.It shows the sky as it would appear to an observer at Lascaux Cave, France, around dawn on July 2, 15,000 BC, looking towards the South. Of course the observer could not see the stars below the horizon, but they would have been visible an hour or so earlier. The stars shown should be visible to the naked eye.

    *All of the stars in this portion of the sky are circled, with darker circles around the brighter stars (three colors for m4.3, 4.8 and 5.3). The circle diameter is 30 arc-minutes (1/2 degree), centered on the star. Orion, Taurus and Pleiades are marked -- Pleiades within the large circle, a smaller circle marking the Bull's eye (Aldebaran). =====

    *The blue lines connect stars in the sky map that follow the contours of the bulls. These lines continue beyond the picture to other stars (we will step back to show a larger view at the end).=====http://www.19thpsalm.org/CreationNarrativeLecture/LascauxSkyMap-Presentation/SkyMapOverlayLines.jpg - A link to the original image is shown so the viewer can see it at full resolution.*The pre-dawn scene here is that Orion is slipping below the horizon -- it will be gone in a few minutes -- and Taurus is soon to follow. Bellatrix (at Orion's bow hand) is just at the horizon and Betelgeuse will be there in just a few minutes. In the next few slides we will zoom in to get a better look.

First, look at Orion. Bellatrix, on the left shoulder, is right at the horizon, and Betelgeuse, on the right shoulder, will fall below the horizon in another few minutes. In other words, Taurus is about to disappear. Simultaneously, the Bull's nose is starting to dip below the horizon, but it will be about another half-hour before the Bull's eye reaches it.Note an unexpected surprise: the line between the nose of Taurus and the back of Bull #15 appears to represent the horizon line. In another minute or two, the painted line will be at the horizon.Until this match-up with the sky chart was made, there seemed to be no logical reason for that line's existence -- it doesn't seem to contribute to the painting otherwise. The line may be intended to join the three stars: 52 Orion at Bull #15's back on the left, Bellatrix in the middle, and Pi.02 Orion at the Bull's nose (and maybe also 32A Orion, to the left of Bellatrix). All of these stars are within about 30 arc-minutes of being on the line, which is excellent accuracy for any hand-made sky chart, especially one made without any precision tools (remember this is the stone age).This same configuration of stars in the sky, occurs every night throughout the year in which the fall of Orion and Taurus is visible -- any clear night between late June and late December in 15,000 BC.
