First to acknowledge the many real virtues of Barker's biographical sketch of the younger brother of Louis XIV. The author has done solid research and mounts plausible arguments to demonstrate financial intelligence and real military accomplishments on the part of a historical figure who is often derided or neglected. Based on her exploration of contemporary accounts - and the extensive Orleans family account books - it becomes clear that the later financial independence and power of the Orleans cadet branch of the Bourbon dynasty had its roots in policies and practiced advocated by the Philippe, the Duke of Orleans.
The down side is Barker's treatment of Philippe's sexuality, which is rooted in a Freudian psychoanalytical approach which has not held up well since the time of the book's publication. "Brother to the Sun King" was published in 1989, and it shows. While Barker deserves some praise for not simply repeating early condemnations of Philippe's life and relationships, all-too-often she seems to be very uncomfortable dealing with sexual matters. The authors makes broad statements, generalizations, and attempts at psychological explanations that veer into psychobabble. This passage, in the final chapter, is somewhat indicative:
"Monsieur and Madame could never recapture the closeness of the early years of their life together as man and wife. The decompensation [?] of Philippe's personality was complete, leading to his retreat into self-destructive tendencies and into the more abject forms of homosexual behavior. In turn, the increasing bitterness of Liselotte and the rejection of her femininity (probably a sublimated lesbianism) were too pronounced for marital reconciliation in any true sense of the word to be possible."
There are no notes, no annotation, for that passage. Nor does Barker provide any first hand primary source evidence for actual same-sex sexual activity on Philippe's part in the last two decades of his life. I am homosexual, and a historian, and yet I really don't know what she
means by "self-destructive tendencies . . . and the more abject forms of homosexual behavior."
An example of a more successful approach to an early modern individual of same-sex sexual orientation is "King James and the History of Homosexuality" by Michael B. Young, recently revised and republished by Fonthill Media in 2016. Perhaps it is time for a similar re-examination of Philippe's sexuality - and the way it was viewed by his contemporaries.
