The mughal emperor Akbar makes every effort to have the inscriptions read, but at that time nobody knows about the script in which the inscriptions have been written, so the effort fails.
Much later, in the modern days, historians discover Ashoka’s pillars (The great Mauryan ruler of ancient India) and learn about the Brahmi script in which Ashoka’s inscriptions have been written. The script on the delhi’s iron pillar is then identified to be written in the same Brahmi script.
What’s so wonderful about it? one should ask what’s so mysterious about it?
More than 1600 years back, to build an iron pillar of this huge size in a single forge itself is an indication of the advanced metallurgy of the ancient Indians. Even in today’s modern technological world it is a great achievement to forge such a huge pillar in a single forge!!!
But there’s more, this pillar which contains more than 98% of pure iron, even after 1600 years has not caught rust!!! It is 100% corrosion resistant inspite of the fact that it is 98% iron!! This indicates one of the great technological achievements of the ancient Indians. Even today it is next to impossible to construct such a huge corrossion resistant iron pillar. Corrosion resistant technologists from all over the world have studied this pillar.Modern day technology uses limestone in the blast furnaces which carries away most of the phosphrous content in the ore in the form of slag. Ancient Indians instead by solid state reduction (used charcoal as a reducing agent) to extract pure iron with low carbon content from the ore.
One of the research opinions about the iron pillar’s corrosion resistant nature is that the high amount of phosphorous (which is 1% of the pillar as opposed to modern day proportions which is 0.05%) has formed a thin protective layer on the surface of the pillar thereby making it corrosion proof. Since other ancient iron works of the same period do not contain such a high quantity of phosphorous, it indicates that the extra phosphorous was intentionally added to the iron pillar.
The inscriptions on the pillar identify the king as “Chandra” (which most historians have related to the great Gupta ruler Chandragupta Vikramaditya) reads as follows (Source Wikipedia)
He, on whose arm fame was inscribed by the sword, when, in battle in the Vanga countries, he kneaded (and turned) back with (his) breast the enemies who, uniting together, came against (him);-he, by whom, having crossed in warfare the seven mouths of the (river) Sindhu, the Vahlikas were conquered;-he, by the breezes of whose prowess the southern ocean is even still perfumed;-
(Line 3.)-He, the remnant of the great zeal of whose energy, which utterly destroyed (his) enemies, like (the remnant of the great glowing heat) of a burned-out fire in a great forest, even now leaves not the earth; though he, the king, as if wearied, has quitted this earth, and has gone to the other world, moving in (bodily) form to the land (of paradise) won by (the merit of has) actions, (but) remaining on (this) earth by (the memory of his) fame;-
(L. 5.)-By him, the king,-who attained sole supreme sovereignty in the world, acquired by his own arm and (enjoyed) for a very long time; (and) who, having the name of Chandra, carried a beauty of countenance like (the beauty of) the full-moon,-having in faith fixed his mind upon (the god) Vishnu, this lofty standard of the divine Vishnu was set up on the hill (called) Vishnupada.
This pillar was erected in the honour of the god Vishnu who is one of the trimurthi (Three gods who represent the life cycle of the Universe: Brahma-The Creator, Vishnu-The Maintainer, Shiva-The Destroyer)
By the way it is interesting to note that more than 2300 years back, ancient Indians knew about the process of iron rusting!
