This narrative, so far as it goes, has served as the basis of the account
given in my text; and I can only trust that it may soon be embodied in
some more accessible form than that of a series of papers in the
Transactions of the Archæological Institute. In a like way, though
Kemble's "Saxons in England" and Sir F. Palgrave's "History of the
English Commonwealth" (if read with caution) contain much that is worth
notice, our knowledge of the primitive constitution of the English people
and the changes introduced into it since their settlement in Britain must
be mainly drawn from the "Constitutional History" of Professor Stubbs.

Bæda's "Historia Ecclesiastica Gentis Anglorum," a work of which I have
spoken in my text, is the primary authority for the history of the
Northumbrian overlordship which followed the Conquest. It is by copious
insertions from Bæda that the meagre regnal and episcopal annals of the
West Saxons have been brought to the shape in which they at present
appear in the part of the English Chronicle which concerns this period.
The life of Wilfrid by Eddi, with those of Cuthbert by an anonymous
contemporary and by Bæda himself, throws great light on the religious and
intellectual condition of the North at the time of its supremacy. But
with the fall of Northumbria we pass into a period of historical dearth.
A few incidents of Mercian history are preserved among the meagre annals
of Wessex in the English Chronicle: but for the most part we are thrown
upon later writers, especially Henry of Huntingdon and William of
Malmesbury, who, though authors of the twelfth century, had access to
older materials which are now lost. A little may be gleaned from
biographies such as that of Guthlac of Crowland; but the letters of
Boniface and Alcwine, which have been edited by Jaffé in his series of
"Monumenta Germanica," form the most valuable contemporary materials for
this period.
