The southern part of Manipur bordering Myanmar reveals petroglyphs and represents an ideal region for studying archaeological remains and human artistry heritage. This paper is an introduction to three petroglyphic rock art assemblages located in the Indo-Myanmar frontier. Comparisoned with dated archaeological materials of adjoining areas, the engraved figures ranges from pre-historic arts to the pre-colonial era of the region. The engraved figures are thematically organized, and contextualized within the subject matter. It argues that the engraved figures like beads, gongs, ponies, and guns are evidence to trade relations with the rest of the world since time immemorial. The motifs were analysed using select colonial ethnographic works, oral literature, folklores, tales current in and around the Indo-Burma frontiers.
