Tamil ⇋ Indus ⇋ Egyptian Connection - 5 - Bronze Mirror

Is Keeladi, Vaigai Valley Civilisation dates back to Sumerian civilisation dating back to 4500-1900BC instead of 600BC?

In my introduction blog, I have already explained the purpose of finding the similarities between Tamil and Sumerian. 

This blog will introduce the bronze mirror excavated in Adichanallur.  This was reported by Catalogue of the Prehistoric Antiquities publised in 1915 as follows.

Item number : 15. Disc with concentric circles aabove (D-7”). Probably used for frying cakes.

Item number : 23. Circular flat place with incised concentric circles on the upper surface; projecting triangular handle (D-6”). Intended for frying cakes.

With the image we can make out that without knowing that it can be a mirror, Mr. Alexander Rea has deciphered it as the frying cakes (as Tamils have the food named Dosa which is cooked using such frying pans).  The design on the center and the concentric circles around proves that it is a bronze mirror.

Bronze mirrors have been recovered from sites like Rakhigarhi, Lothal, Dholavira and Mohenjodaro (locations of Indus Valley Civilisation) as well. One illustrated here have more or less similar design.

The Egyptian bronze mirror looks as follows.  The mirror of Adichanallur might have missed the handle as shown.

Brooklyn museum explains the mirror as follows.

The Egyptians first used mirrors in the Old Kingdom (Third through Sixth Dynasties; circa 2675–2170 B.C.E.) if not earlier. The design—elliptical disks supported by handles shaped like papyrus plants—symbolized the moment when the creator-god emerged from the primordial swamp in the form of the sun. The Egyptians believed that all life began in this so-called First Moment. When they picked up their mirrors each morning they were thus reminded of creation.

The shape of mirrors changed over time. In the Eighteenth Dynasty, the traditional oval disk was replaced by a circular form. Handles appeared in a wide variety of shapes, including images of animals, adolescent girls, and papyrus flowers.

How about the similarity of all these mirrors?

The comparison between these findings will surely take the civilisation on the River Vaigai back to the same time as Egyptian 2675–2170 BC and Mohenja-daro Indus 2700 to 18/1700BC Civilisations instead of 600BC.
