THIS is the first of a series of six talks by Major Gordon Home, who has specialized in Roman archaeology for some years, and himself began the excavations of the Roman fort of Reeulver last year. He has written books on Roman York, Roman London, and Roman Britain, the last of which was published in 1927. The Roman occupation, which really began with the conquest of the Emperor Claudius, marks the beginning of a real social life for the country. Major Home in his first talk covers the two raids-they were no more-by Julius Cœsar, the gradual advance of the legions to the north and west, the first colonization of such towns as Camulodunum (Colchester), and the growth of peaceful conditions behind the military shield of the Northern walls. He deals with the exploitation and taxation of the wealthier Britons, and the consequent desperate revolt and its failure, and a century of increasing trade and wealth for Southern Britain. Finally, he describes the disaster of 367 A.D.. and the decline of Roman control owing to the gradual withdrawing of tho garrisons to guard the more vital centres of the crumbling empire.
