I've been looking for some site that could do this work but I not being lucky finding one...
What I would like to know, and maybe someone with more knowledge and ability for the stars stuff could answer me this: Was there a moment in time where Ophiuchus was in the sky's azimuth and, at the same time, having the Piscis Austrinus and Aquarius constellation on the Eastern horizon? Thank you in advance. Or...Secondary question...If there is a time in the year where were closer to this scenario when would it be? (All this for the Northern hemisphere, south of Portugal) -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

Now try again with another set of stars - see if the match is any better or worse.
 I notice you've deleted quite a few stars in the comparison (in the middle) - did the neolithic guys get so drunk they couldn't finish it?  I remember seeing an overlay once of a good match between a set of stars and New York subway stations or something. That was a good demonstration of what you can do with star patterns.

Maybe they've run out of stones or needed some space for their allucinated raves...

There are some pretty obvious patterns in the sky in that area. For one, Serpens (Caput and Cauda) and the bottom of Ophiuchus trace out a long snake-like line. The summer triangle (Vega, Deneb, and Altair) and, for that matter, the Milky Way should also be prominent in any drawing of the summer sky.

Michael, Altair was my departing point for being the shiniest star in the area, it's the one on the left in this image, the one on the lower right could be Vega and what about Deneb?...: http://i16.photobucket.com/albums/b14/ustr...ndres_fig04.jpg !Suppositions oh suppositons!

Actually, I don't see any recognizable patterns in either picture. Could you give us some background on this or a link?

Another very distinctive pattern is Delphinus the Dolphin, a very compact grouping of stars which should be visible even if the stars are drawn without respect to magnitude. Since I don't see it in either picture, I don't think either one is a good representation of that sky.
