This remarkable book readably represents a formidable effort of research, drawing on the rich studies of history, art, and paleography that have accumulated over centuries, and particularly on the last forty years of archeology. Lillian Lan-ying Tseng colligates images that no one earlier has studied side by side, and draws from them quite original conclusions. I find her arguments ambitious, ingenious, and persuasive. . . . They show once and for all that pictures are as important as verbal records for understanding the history of cosmology and astronomy.
