The Birds of Australia 1910-28 by Gregory Mathews is a monumental work which took over 18 years to produce, comprising over 630 superb original hand coloured lithographs, drawn by J. Keulemans, R. Green and H. Gronvold. Rarer than John Gould’s work on Australian birds, with only 225 sets ever produced, most of which are in institutional collections and the last record of the complete individual lithographs being offered for sale in Australia was over 20 years ago. Gregory Macalister Mathews (1876-1949) born in NSW to a wealthy grazing family. He settled in England at the turn of the century and over the next 40 years with the help of his secretary Tom Iredale, he devoted his life to Australian ornithology. His contribution, particularly taxonomy was profound. Along with John Gould’s Birds of Australia, 1840-1869, Mathew’s’ The Birds of Australia, is a cornerstone of Australian ornithology.
