The Ghost of Galileo

The appearance of Galileo's Dialogue in a forgotten painting launches John Heilbron's exploration of science and culture in Stuart England, and its deep connections with continental Europe. Ranging across art history, politics, and religion, he unravels the painting's mysteries, setting its sitters and painter against their rich cultural backdrop.

In 1643/4 the once-famous Francis Cleyn painted the unhappy young heir of Corfe Castle, John Bankes, and his tutor, Dr Maurice Williams. The painter is now almost forgotten,the painting much neglected, and the sitters themselves have left little to mark their lives, but on the table of the painting lies a book, open to an immediately identifiable and very significant page. The representation omits the author's name and the book's title; it sits there as a code, as only viewers who had encountered the original and the characteristic figures on its frontispiece would have known its significance. The book is Galileo's Dialogue on the two chief world systems (1632), the defence of Copernican cosmology that incited the infamous clash between its author and the Church, and its presence in this painting is no accident, but instead a statement of learning, attitudes, and cosmopolitan engagement in European discourse by the painting's English subjects.

Grasping hold of the clue, John Helibron deciphers the significance of this contentious book's appearance in a painting from Stuart England to unravel the interlocking threads of art history, political and religious history, and the history of science. Drawing on unexploited archival material and a wide range of printed works, he weaves together English court culture and Italian connections, as well as the astronomical and astrological knowledge propagated in contemporary almanacs and deployed in art, architecture, plays, masques, and political discourse. Heilbron also explores the biographies of Sir John Bankes (father of the sitter), Sir Maurice, and the painter, Francis Cleyn, setting them into the narrative of their rich and cultured history.
