Abstract :There is little authentic knowledge about the ancient history of Idukki region. The urn burials in
the high ranges that date back to the megalithic period are the sole indication of human presence over
the region. The burial vaults called Pandukuzhis, the Menhir and dolmens found in the Anchunad valley
in the present Deviculam taluk substantiate this argument. The rock art in the Anchunad Valley has the
depictions of the material life and culture of the prehistoric and megalithic periods. These petro graphs,
petro glyph and dolmens and other remains of Mesolithic and megalithic cultures of the Valley help us to
reconstruct the history of the prehistoric and megalithic people. They give us an insight into the mental
world of the prehistoric and megalithic people’s imaginary relations, fantasies and social milieu of ideas
and institutions. The Anjunadu Valley is considered as the treasure house of pre-historic and megalithic
culture. The Anjunadu Valley is littered with a lot of dolmens and petrographs and petroglyph. This is
the only place in Kerala where we can see petrographs and these are linked with the dolmens of the
valley. These rock art sites of the valley as well as the megalithic remains of the valley give us an insight
into the material milieu of subsistence of prehistoric and megalithic times. The present study is an
attempt to situate Anjunad Valley in the pre-history of Kerala.
