they were farmers, fishermen.’
‘By and large …?’
‘They were great explorers, too.
They discovered North America five hundred years before Columbus
thought he had. They got as far as the Mediterranean, Russia.
You have to remember that most accounts of the Vikings are
written by the Christians who displaced them. Somewhat biased
accounts.’
‘You know this for a fact?’
The Doctor gave Jo a hurt look.
‘What I do know
for a fact
is
that they’re the only humans ever to name a day of the week
after bathtime. Washing once a week was pretty advanced stuff
two thousand years ago.’
Jo laughed.
‘Well,’ said the Doctor. ‘Shall we
look around?’
Jo nodded. ‘Let’s.’
The Doctor brought up the outside
view on the TARDIS’s scanner screen. They were treated to the
sight of a peaceful forest, with snow deep on the ground and
thick on the branches of the trees, although it appeared to be a
bright and sunny day otherwise.
‘Seems quiet enough,’ said the
Doctor.
He shut down the screen, opened
the door and they headed out.
‘Cold,’ said Jo.
‘Will you be warm enough?’ asked
the Doctor. ‘I could always fetch my Inverness cape for
you?’
‘I’ll be fine,’ said Jo hurriedly.
She shot a quick smile at the Doctor so as not to hurt his
feelings.
Their feet crunched noisily into
the snow, which was frozen hard.
‘Which way do we go?’ asked
Jo.
‘I’m not sure,’ said the Doctor.
‘Let’s circle around. It can’t be far. There should be a large
temple complex. And a village serving it.’
Jo stopped and looked back over
her shoulder. ‘Will the TARDIS be all right?’
‘She’s tougher than I am,’ said
the Doctor seriously. ‘And, anyway, I have a theory.’
‘Yes?’
‘Yes. You see, the whole nature,
shape and even the modern blue pigment of the TARDIS is so
deeply unfamiliar to the primitive mind that, although the optic
nerve registers its presence, the brain cannot decode what it is
seeing. The primitive visual cortex is unable to relay
information about it consciously to the viewer. In effect, even
though her chameleon circuit is still damaged, she’s as good as
invisible. She’ll be just fine.’
‘That’s remarkable,’ said
Jo.
‘She is a remarkable old girl in
many ways,’ said the Doctor. ‘Let’s move, shall we? We’ll be
warmer if we walk a little faster.’
They made their way deeper into
the forest. As long as there wasn’t another snowfall it would be
easy enough to find their way back to the TARDIS from the trail
of their footprints in the snow.
The woodland was on sloping land,
and they headed gently downhill through a mixture of birch and
ash and conifers until, finally, they saw the trees thinning out
a little in front of them.
‘I hear a river somewhere,’ said
Jo.
‘Yes,’ said the Doctor, nodding.
‘That way.’
Very soon they glimpsed clear
green water flowing rapidly in a wide and strong river, whose
banks were covered with snow and ice.
‘This way,’ said the
Doctor.
‘How do you know?’
‘Because rivers mean settlements
sooner or later.’
‘Sooner, I hope. I’m
freezing.’
‘I could still go back for my cape
…’
‘Look, Doctor! What’s
that?’
Jo pointed downstream to the
opposite bank, where there was a huge wooden construction. As
they moved closer, they saw what it was – a vast waterwheel fed
by a channel from the river. Then they saw that beyond it was
another one, exactly the same, and beyond that, more – six of
them in total – and all drawing water from the channel
underneath the heavy wooden wheels, which turned slowly but with
a power that was somehow threatening.
‘Fascinating.’
‘Is there a way across?’
‘Let’s head downstream. Maybe
there’s a bridge. I wouldn’t want to cross that river, even on a
summer’s day.’
The river was deep and moved in
