During the first visit here, my friend Rama Dasa from this village showed us ancient petroglyphs of Sanganakallu. Rama Dasa shared the knowledge about this hill which he's been exploring since childhood days. We saw hundreds of rock etchings depicting humans and animals such as bulls, horses, elephants, tigers, serpents and birds. I must mention the bull-axe wheel, a complex drawing consisting of 5 axes and 5 bulls. Rama Dasa said that every drawing had a meaning, they connected our world on this planet to the cosmic world. The 5 hour tour clambering up the dolerite dyke was a tiring exercise. By 1 PM it was too hot for comfort, we ended the tour.
December 22, 2013The second visit. We- Mohan mama, Rama Dasa and I -arrived here quite early, it was winter solstice, an important day in astronomy. Rama Dasa had gone to a field behind this hill to mark the shadow of this hill's peak - he marks the position of the shadow every year to study its movement. With that observation Rama Dasa understands the relative position of Earth and Sun. In this picture below, the moon is positioned just above Peacock hill, few minutes after shooting this picture the moon sank behind the rocks. Being here on Winter Solstice Day was a coincidence, objective of this visit was to see the Neolithic tools factory atop this hill i.e. the summit between Peacock hill and Dolerite Dyke.
Rama Dasa demonstrates how a man would have worked the mill. In his hand is the grinding stone which would go round and round crushing grains in the pit.
The grinding stone had multiple purposes, not only it was used to grind grains but it could also be used to sharpen tools. For instance this is a well formed stone axe but its unfinished. The edges would be rubbed patiently until they become smooth cutting edges.
