The visible universe; chapters on the origin and construction of the heavens
A popular astronomy treatise by the Irish amateur observer J. Ellard Gore, published in London by Crosby Lockwood and Son in 1892 for general readers interested in stellar structure and the nebular hypothesis. The plates are negative star charts: white dots of graded size on solid black grounds, linked by dotted lines and labelled with Greek letters, useful as star fields, constellation diagrams, and telescope-view textures.
