If you are interested in the subject, then books just don't come any better than this; it's pure magic. I admit the style takes a little getting used to at first but, once you are into it the detail and information available is amazing. Mr Allen must have had a classical education and then some!
It covers all the constellations and the Milky Way in consummate detail and the information isn't just regurgitated piecemeal. It's interspersed with items of poetry which, for me, really brought the descriptions to life. Bear in mind however that it was written in 1899 and some of the statements Allen makes may refer to constellations that are no long extant, and search as I might I found nothing about the teapot or the steering wheel :-) But this is to nitpick, if you want to know the meanings of the names of the stars and constellations, never mind that at the finish we aren't really sure whether the names are based on tales from Sumer, Akkad, Babylon, China, Egypt, Greece, Rome, Arabic or the 16th / 17th centuries, this is the book, it's a journey in itself.
