To the general modern authorities for French history for this period must now be added the valuable new Histoire de France edited by M. Ernest Lavisse (Hachette), of which the three half-volumes covering this period are now published. They are: Les Premiers CapÉtiens (987–1137), by Achille Luchaire, II. ii.; Louis VII., Philippe Auguste, Louis VIII., by Achille Luchaire, III. i.; and Saint Louis, Philippe le Bel, les derniers CapÉtiens directs, by Ch. V. Langlois, III. ii. A large collection of facts covering the whole subject of this book will soon be available in the relevant volumes of the Cambridge MediÆval History. The maps in R. L. Poole’s Oxford Historical Atlas are very valuable for the elucidation of the historical geography of the period.
