When Boniface was establishing religious houses in Germany he sent to Abbess Tetta, asking that Lioba might be allowed to come over and help him. She went, and Boniface put the monastery of Bischofsheim on the Tauber, a tributary of the Main, under her care. Here she carried on the traditions of Wimborne, for she taught and encouraged learning in every way. Her rule was sane and wise. Her biographer says of her, "She was careful always not to teach others what she herself did not practise. Neither conceit nor overbearing found any place in her disposition; but she was gentle and kind to everyone without exception. She was beautiful as an angel and her conversation was charming. Her intellect was renowned, and she was able in counsel. She was catholic in faith, most patient in hope, and of widespread charity. Though her face was always cheerful, she never broke into hilarious laughter. No one ever heard an ill-natured remark fall from her lips, and the sun never went down upon her wrath. Though she provided food and drink with the greatest liberality for others, she was very moderate herself; and the cup from which she used to drink was called by the sisters, on account of its size, 'darling's little mug.'" She knew that a heedful mind is necessary for both prayer and study, and so she insisted upon moderation in holding vigils. She allowed herself, and the sisters under her, a short rest after dinner, especially in the summer time; and would never willingly allow people to stay up late; for she maintained that loss of sleep meant loss of intelligence, especially in reading. Her methods were undoubtedly successful, for Rudolf says that among the other convents for women in Germany, there was scarcely one which had not teachers trained under Lioba, so eagerly sought after were her pupils. Here this account of some early double monasteries must end. In England they probably existed right up to the Danish invasions of 870, and disappeared in the general devastation of the country during the succeeding years. The organisation, however, appears again in this country in the C12, and even as late as the C15. The order of S. Gilbert of Sempringham in the C12 was a double one, and the only order which actually had birth in England. It was, however, entirely lacking in that intellectual activity which was a special feature of the earlier double monasteries, among both men and women, and which, from the secular point of view, gave to the Anglo-Saxon nunneries a place not incomparable with the women's colleges of the present day. The latest double monastery in England was that of S. Bridget of Sion, near Isleworth, on the Thames. Reference has been made only to the more important early double monasteries in England; but there are others which may or may not come under this category. Of these some are Whitern in Galloway, Carlisle, Caistor in Northamptonshire, Gloucester, Strenshall in Staffordshire, and Lyminge in Kent.
