Sims-Williams, Patrick, The Book of Llandaf as a historical source, Studies in Celtic History, Woodbridge: Boydell & Brewer, 2019.  
Contents: Introduction; The Book of Llandaf and the early Welsh charter; The origin of the Llandaf claims; The charters in the Book of Llandaf: forgeries or recensions?; The authenticity of the witness lists; The integrity of the charters; The chronology of the charters; The status of the donors and recipients of the charters; The fake diplomatic of the Book of Llandaf; The Book of Llandaf: first edition or seventh enlarged revision?; A new approach to the compilation of the Book of Llandaf; The evidence of the doublets; The Book of Llandaf as an indicator of social and economic change; The royal genealogical framework; The episcopal framework; Afterword; Appendix I: Concordance and chart showing the paginal and chronological order of the charters; Appendix II: Maps of grants to bishops; Bibliography.
abstract:
The early-twelfth-century Book of Llandaf is rightly notorious for its bogus documents - but it also provides valuable information on the early medieval history of south-east Wales and the adjacent parts of England. This study focuses on its 159 charters, which purport to date from the fifth century to the eleventh, arguing that most of them are genuine seventh-century and later documents that were adapted and "improved" to impress Rome and Canterbury in the context of Bishop Urban of Llandaf's struggles in 1119-34 against the bishops of St Davids and Hereford and the "invasion" of monks from English houses such as Gloucester and Tewkesbury. After assembling other evidence for the existence of pre-twelfth-century Welsh charters, the author defends the authenticity of most of the Llandaf charters' witness lists, elucidates their chronology, and analyses the processes of manipulation and expansion that led to the extant Book of Llandaf. This leads him to reassess the extent to which historians can exploit the rehabilitated charters as an indicator of social and economic change between the seventh and eleventh centuries and as a source for the secular and ecclesiastical history of south-east Wales and western England.

Sims-Williams, Patrick, Buchedd Beuno: the Middle Welsh Life of St Beuno, Dublin: Dublin Institute for Advanced Studies, School of Celtic Studies, 2018.  
abstract:
Beuno was a seventh-century abbot, active in eastern and north-western Wales. The fourteenth-century Middle Welsh Life of St Beuno is an attractive literary text which is also important historically, being based on a lost Latin original, as shown in the comprehensive introduction to this edition. As the language of the text is unusually simple, the edition is accompanied by a short grammar of Middle Welsh and a full glossary so that it can be used by complete beginners.

Raybould, Marilynne E., and Patrick Sims-Williams, Introduction and supplement to the Corpus of Latin inscriptions, Aberystwyth: CMCS Publications, 2009. viii + 344 pp + 16 maps.  
abstract:
In this second volume Raybould and Sims-Williams complete their Corpus of Latin inscriptions of the Roman Empire containing Celtic personal names with a final collection of texts and translations. They also list and analyse the Celtic names found in both volumes and map their geographical spread, from the Atlantic to the Black Sea.

The illustration on the front cover shows part of a second-century tombstone in the museum at Mannersdorf am Leithagebirge, Austria (no. PAN 113 in this Supplement). Nertomarus and his wife Toutomara erected it to commemorate themselves. His name Nertomarus is from Celtic nerto- 'strength' and maros 'great' (compare medieval Irish nertmar and Welsh nerthfawr 'strong'), while Touto- mara combines touto- 'people, land' (Irish tuath, Welsh tud) with the feminine mara 'great'.

abstract:
[FR] La localisation des Celtes d’après Hécatée, Hérodote et d’autres auteurs grecsC’est par erreur que l’on a compris le texte d’Hécatée et d’Hérodote, deux contemporains des premières inscriptions celtiques du Nord de l’Italie et du Sud de la Suisse, comme des documents localisant les Celtes en Autriche et dans le Sud-Ouest de l’Allemagne, ce qui a eu pour résultat malheureux de conférer l’étiquette celtique à la culture halstattienne de cette région. En réalité, Hécatée et Hérodote renvoient à une localisation en Gaule – comme il a été confirmé plus tard par Timagète, Pythéas et Apollonius de Rhodes –, ainsi que, peut-être, dans une partie de la péninsule Ibérique, comme il a été affirmé par Éphore au IVe siècle. L’aire ou les aires celtiques de la péninsule auxquelles se réfèrent Hérodote et Éphore ne peuvent pas aujourd’hui être définies, mais il n’est pas nécessaire de les faire s’étendre à l’ouest de la Celtibérie – au centre de l’Espagne –, d’où proviennent, plus tard, les plus anciennes inscriptions celtiques de la péninsule. Au milieu du IVe siècle, le Pseudo-Scylax fait mention de l’installation de Celtes en Italie dans la plaine du Pô, de même peut-être que Apollonius au siècle suivant. À l’époque d’Apollonius, les Celtes étaient déjà engagés dans des migrations vers l’Ouest, si bien que tous les témoignages postérieurs concernant leur localisation, même les données toponymiques, sont d’une valeur incertaine comparée à celles des premiers auteurs, notamment Hécatée et Hérodote, malgré leurs limites et leur point de vue méditerranéen. Certes, les premiers auteurs sont eux-mêmes trop tardifs pour nous indiquer la région où sont apparus les Celtes et la langue celtique. Cependant, nous pouvons dire négativement qu’ils ne permettent d’appuyer ni une localisation à l’Est, en Allemagne ou en Autriche, ni une localisation à l’Ouest sur le rivage atlantique. Ce qu’ils nous disent s’accorde certainement avec une origine des Celtes située en Gaule, mais cette hypothèse ne peut être développée sans attribuer des identifications ethniques spéculatives aux données archéologiques préhistoriques.

[EN] Hecataeus and Herodotus, who were contemporary with the earliest Celtic-language inscriptions in northern Italy and southern Switzerland, have been misunderstood as localising the Celts in Austria and south-west Germany, with the unfortunate result that its archaeological ‘Hallstatt culture’ has been wrongly labelled ‘Celtic’. In fact, Hecataeus and Herodotus point to locations in Gaul (as later confirmed by Timagetus, Pytheas, and Apollonius of Rhodes) and possibly in part of the Hispanic Peninsula (as stated by Ephorus in the fourth century). The Celtic area or areas in the Peninsula to which Herodotus and Ephorus may refer cannot now be defined, but need not have extended west of Celtiberia in central Spain, which is later the source of the earliest Celtic inscriptions in the Peninsula. In the mid-fourth century the Italian Celtic settlements around the Po valley are referred to by Pseudo-Scylax, and possibly by Apollonius in the third. By Apollonius’ day, Celts were already migrating eastwards, so that any subsequent evidence for their location, including onomastic data, is of doubtful value compared to that of the earlier writers, especially Hecataeus and Herodotus, despite their evident limitations and Mediterranean perspective. Even the earliest writers are too late to guide us to the area where the Celts and the Celtic language emerged. Negatively, however, we can conclude that they neither support a location in Germany or Austria in the east nor support a location on the Atlantic seaboard in the west. What they say is certainly consonant with Celtic origins in Gaul, but that hypothesis cannot be taken further without attaching speculative ethnic labels to prehistoric archaeological data.

Sims-Williams, Patrick, “The four types of Welsh yn”, Transactions of the Philological Society 113:3 (2015): 271–406.  
abstract:

This paper discusses and categorises the various medieval and modern Welsh prepositions and particles yn and the initial mutations that follow them. It investigates possible manuscript variants such as Old Welsh int and it and Middle Welsh y, and examines variations in mutation. Historical explanations are suggested, including a new explanation of the absence of mutation in the productive yn + verbal noun construction, which is argued to have spread from the construction in which possessive pronouns between yn and the verbal nouns of intransitive stative verbs prevented yn from mutating the verbal nouns.

abstract:
After a hiatus following the Old Welsh period, Welsh manuscript evidence resumes c. 1250, and can now be studied in minute detail owing to the construction of a palaeographical chronology for the manuscripts and the availability of machine-readable and other modern editions. These reveal that the so-called ‘sandhi h-’ after first-person pronouns in modern literary Welsh is not ancient, but slowly emerged in the late thirteenth century as a hypercorrect phonetic tendency after nasal consonants which gradually became grammaticalised after pronouns ending in a nasal.
