In existographies, Joseph Hager (1757-1819) was an Italian-born ancient languages scholar noted for his 1801 translation of some Babylonian bricks, the dissertation of which he makes an early Brahma = Abraham connection.
In 1797, the directors of the East India Company obtained 10 or 12 specimens of bricks near Hillah (Helle), a small town on the Euphrates, near Bagdad, the then supposed location of ancient Babylon, which contained indented scroll or label in letters. The bricks reached London in 1801 and were the task of copying them and describing them was given to Hager.
Babylon | Egypt
In 1801, Hager, in his Dissertation on the Newly Discovered Babylonian Inscriptions, over-zealously attributes these inscriptions to be the world’s oldest language, conjecturing that the tower of Babel was bigger than the Egyptian pyramids, and that the Egyptians themselves, who pretend to be the instructors of all nations, probably derived their pyramids and obelisks from Babylon; the gist assertion (pgs. xviii-xix) of which he explains as follows:
“By the Babylonian bricks here exhibited, the whole difficulty in regard to their origin is removed; as it is evident that Babylon, in point of cultivation, was much earlier than Persepolis, and that the Chaldeans were a celebrated people, when the name of the Persians was scarcely known. To confirm this opinion, and by it to prove that the Persepolitan characters were derived from the Babylonian, I have thought it necessary to begin this work by a brief examination of the antiquity, extent, and sciences of the Babylonians; and through scantiness of original monuments, to prove by astronomy, architecture, and languages, their well-founded claim to antiquity. At the same time, I have endeavored to show that not only the Persians, but also the Indians, were disciples of the Chaldeans; and that the Egyptians themselves, who pretend to be the instructors of all nations, probably derived their pyramids and obelisks from Babylon. Proceeding then to the Babylonian inscriptions, I have shown their similarity to that celebrated alphabet which the Indians call divine or celestial, (deva-nagari) because they believe that it was communicated by the Deity himself in a voice from heaven; and I have tried to prove that they were not derived from heaven, but from our earth, and from the borders of the Euphrates. I have confirmed my assertion by means of the Tibetan characters, those acknowledged descendants of the Indian ones, and thus endeavored to invalidate the opinion of that great antiquity and boasted originality of the Bramins.”
This Babylon (2300BC) before Egypt (3100BC) conjecture, to note, is in correct, being that modern evidence indicates that earliest mention (Ѻ) of the city of Babylon is found in a clay tablet from the reign of Sargon of Akkad (2334–2279BC).
Brahma | Abraham
On Brahma and Abraham, Hager says:
“In regard to Brama [Brahma], I shall only observe, that according to the researches of the learned Thomas Hyde , the Persians, those neighbors of the Indians, called their most ancient religion the religion of Abraham, and that Zoroaster [c.1000-600BC] (Ѻ), their legislator, himself is never called otherwise but Ibrahim, or Abraham Zerdusht [N1]. The same may be said of the Arabians, the neighbors of the more southern India, amongst whom Abraham was believed to have founded the famous temple of Mecca, to say nothing of the Egyptians, whom he instructed, as Josephus (37-100) (Ѻ) attests, in the Chaldaic astronomy [N2]. Whilst we find then such a number of Persian words in the ancient language of India, which prove the great communication which must have existed between both countries, there is no wonder if the name of Abraham, the prophet of Persia, had been likewise adopted in India, and the testimony of those authors confirmed who pretend the Bramins to have been disciples of the Persians [N3]; and the Chaldaic name of the sacred fire, the worship of which is one of the principal points of the religion of Zoroaster, shows the primeval origin of the ancient religion of Persia.”
Quotes | On
The following are noted quotes on Hager:
“Let me not be called a wicked atheist for seeing the likeness between Brahma and Abraham; for what says the learned Joseph Hager : ‘As the Indian alphabets are all syllabic, and every consonant without a vowel annexed is understood to have an A joined to it, there is no wonder if from Abraham was made Brahma; and thus we see other Persian words in the Sanskrit having an a annexed as deva from div, appa from ab, deuda from deud, etc.’”
