Tatlock, Richard. An English benedictional, 1964: title page (translated and adapted from the Leofric missal)
Wikipedia 26 October 2019: (The Leofric Missal is an illuminated manuscript, not strictly a conventional missal, from the 10th and 11th century, now in the Bodleian Library at Oxford University where it is catalogued as Bodley 579. It comprises a sacramentary (probably created around 900 in Lotharingia) with additions probably made in England in the 10th century; a calendar with other computus material, probably English of the 10th century; and a variety of texts by different hands, some on additional leaves and some in blank spaces within the other manuscript sections, in English hands of the 10th-11th centuries.) https://en.wikipedia.org/wiki/Leofric_Missal
