Archaeologists have discovered cup-like depressions and linear markings on a rock in Delhi's Central Ridge forest, potentially dating back to the pre-Ashokan era.

These findings, noticed by naturalist Pradip Krishen and activist Chetan Agrawal, show patterns resembling ancient rock art found in other parts of India.The carvings, embedded in a large outcrop near Sardar Patel Marg, suggest human activity predating Emperor Ashoka's inscriptions.Researchers like Nayanjot Lahiri argue these markings could be over 2,000 years old, possibly linked to early settlements.The discovery highlights the need for protection of such sites, as they offer insights into India's ancient past.While some cupules resemble Ashokan Brahmi script, others may predate the Mauryan era.The Delhi Forest Department is urged to safeguard the area, emphasizing that archaeological sites are endangered like flora and fauna.These findings add to ongoing debates about India's prehistoric cultural heritage.
