The occurrence of a cross design is noteworthy. From comparative study of these etched designs it would appear that the central point in the chronology of the beads at Porkalam is \*c.\* 1st century A.D. with a margin on the earlier side. No other evidence except that of indirect comparative study of other finds including the typology of burials is available for dating the urn burial. - [Previous: v2.c42.619](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c42.619) - [Next: v2.c42.621](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c42.621) - [Up: v2.c42](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c42) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v2.c42.620](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c42.620) · Pramāṇa
