I am indebted to Jacquetta Hawkes, The First Great Civilizations ( London, 1973), particularly for the translation of the Sumerian poem on the god-prince Enki as the original patron of agriculture and the arts. Joseph W. Alsop has written the only history of art collecting and patronage until Renaissance Italy in The Rare Art Traditions ( London, 1982): his researches and examples are admirable, although his thesis is open to question. The lines on the Druid temples are by William Stewart, translating into verse the Latin History of Scotland by Hector Boece, published in Paris in 1526, and republished as The Buik of the Cronicles of Scotland ( Edinburgh, 1535): Stewart lived in a century absolutely aware of the power of royal patronage. The words of Pericles are recorded by Thucydides in his History of the Peloponnesian War. My translation of Thucydides is taken from R. W. Livingstone illuminating editorship of The Legacy of Greece ( Oxford, 1922). I am further indebted to J. C. Stobart, The Grandeur That Was Rome (rev. ed., London, 1934) for his discussion of the patronus in Roman society, and to Sir Mortimer Wheeler, Roman Art and Architecture ( London, 1964) for the stress on the secular nature of Roman art.
The quotation from Percy Bysshe Shelley comes from his Ode to the West Wind. Equally he lamented ruined empires in Ozymandias with its legend on the pedestal of the destroyed statue:
'My name is Ozymandias, king of kings. Look on my work, ye Mighty, and despair!' Nothing beside remains . . .
