The sources and their interpretation 77
of artefacts, eagerly acquired by antiquaries and museums. Some, furthermore,
lay underneath distinctive features in the landscape such as barrows or churches
and others were fairly elaborately constructed with tiled or stone-walled sides
or lay in stone sarcophagi, further facilitating their observation in the course
of agricultural activity. On the other hand, early medieval building techniques
tended to make use of wood rather than stone, making structural remains, in
the forms of holes and slots or isolated pad-stones for timber stakes, posts and
beams, more difficult to observe. Furthermore, in the case of western European
towns and rural sites on or near Roman villas, early medieval archaeology was
lost through the simple fact that its ephemeral traces overlay more easily recog-
nisable Roman structures, stone-built and with tiled or even mosaic floors.
Excavation techniques throughout Europe all too often involved the location
of stone walls, the recovery of the basic plan of the building through follow-
ing the lines of these walls, and then digging down in the areas so delineated
until a recognisable floor surface was found. These methods, even where, as
was not commonly the case, the excavators had any interest in post-Roman
archaeology, meant that evidence from the early Middle Ages usually ended
up on the spoil heap. Perhaps it is no coincidence, therefore, that some of the
first early medieval towns to be studied archaeologically were those without
Roman precursors – Dorestadt in the Netherlands, Hamwic in Britain, Hedeby
in northern Germany, Helg
¨
o and Birka in Sweden, for example. As the twen-
tieth century progressed, however, archaeology became ever more technically
sophisticated. Although excavation techniques altered radically, the recovery
of data is no longer restricted to ‘digging’ as field survey methods have devel-
oped.

The scientific aspect of archaeology has also expanded dramatically so
that complex technologies exist not simply for quantifying and dating various
materials but also for examining the early medieval natural environment and
the states of health, diseases and life expectancy of the people of the early
Middle Ages.
Again we are confronted not simply with an array of new data, better recov-
ered and of infinitely greater variety than existed in 1911. The lens through
which those data are viewed in order better to understand the early medieval
past has also changed radically. When medieval archaeology first emerged it
was, as mentioned, used simply as illustrative material and it can be argued
that this attitude has never completely disappeared. The theory of archaeol-
ogy has developed considerably in the last century.

has also become an academic discipline with an establishment in university

The classic introduction to excavation remains Barker (1993), but see now Roskams (2001). For
fieldwalking, see Fasham et al. (1980), and for ‘geophysics’, see Clark (1990).

overview.
