iefs concerning the Hoogley Bridge, and the culture-relationship of
the bridge-builders to the surrounding people in both cases is that of
an advanced civilisation to tribesmen. Now if these conditions of
modern India are repetitions of the conditions of ancient Britain in
the days of Lundinium, and of this there can be but little doubt,
there is no difficulty in understanding to what part of history these
traditions have led us. We are again in the days when London Bridge
was a marvel--a marvel which sent travelling through the Celtic homes
of Britain a new application of the treasure myth which they had
inherited from remote ancestors. The marvel lived on through the ages
when London was in the unique position of being an undestroyed city in
Saxon times, times which witnessed the destruction of all other
cities of Roman foundation,[32] and the sending forth of the Celtic
refugees to Brittany.[33] The accumulation during a long-continuing
period of conceptions of treasure being found by way of the bridge
leading to London, would become the direct force for keeping the
tradition alive; and while the facts of history show us the important
position of London during the period which witnessed the departure of
the Celtic Bretons to their continental home,[34] the facts of
tradition show us the Celtic tribesmen deeming it a way to wealth
through the magic potency of dreamland. The Celtic tribesmen stood
outside Roman Lundinium. Its life was not their life, and their
conversion of its position into a mythic treasure house or a mythic
road to treasure, and their association of it with the bloody rites of
the foundation sacrifice, are in strict accord with the historical
relationship of the tribal life of Celtic Britain to the city life of
Roman Lundinium.

I may be permitted perhaps to emphasise this significant accordance of
history and tradition when working together. I have already alluded to
the fact that I have worked out the history of London independently,
and upon lines quite different from the present study. I have
therefore a wider grasp of the two currents of history and folklore in
this particular case than could in the ordinary way fall either to the
historian or to the folklorist. That I can find in both just the
complementary facts which help to realise the whole situation, to fill
in the gaps of history which nowhere directly tells of the
relationship of Roman Lundinium to the British Celts, to extend the
outl
