An iron sword measuring 40 cm, the longest sword so far, was unearthed at Konthagai, which is a part of the Keeladi cluster near Madurai on Thursday.
The sword made of iron was found 71 cm below the ground, stated an official release.
The Deputy Director of Archaeology and the director of Keeladi excavations R. Sivanandam said the sword could have belonged to a warrior or a local chieftain of those times.
It was found along with the grave goods (favourite things of the deceased which are buried along with them in an urn), skeletal remains and black and red ware vessels in the urn.
It was the first sword unearthed during the eighth phase of the excavation being carried out at Konthagai, said M. Ramesh, Co-Director of Keeladi excavation.
