During the iron age or darkest yuga, humanity is mainly focused on materialism. In the book of Daniel it is named as a last of four kingdoms, identified as the Roman Empire. The former three identifie as follows, according to the mentioned religious clergy:
| Yuga | Age | Salomon de Troyes | Jerome of Stridon |
| Dwapara | Bronze | Macedonian Empire | Macedonian Empire |
| Tetra | Silver | Chaldean Empire | Achaemenid Empire |
| Satya | Gold | Babylonian Empire | Babylonian Empire |
They differ in their second kingdom, respectively ruled by Belshazzar & Cyrus the Great, while the book even mentions Darius the Mede, a king between those protagonists:
- Did Anatoly Fomenko identifie Charles I as Cyrus II correctly?
- Did Joseph Scaliger fail to position Darius the Mede in mainstream history?
Which leads us to the following questions:
- Is Belshazzar a partial duplicate of Flavius Belisarius?
- Is Darius the Mede a partial duplicate of Narses the Eunuch?
Flavius Belisarius & Charles of Anjou both captured Naples with a trick, as Cyrus the Great did similarly with Babylon, all partial duplicates of final stage of the Trojan War: Is the seizure of Constantinopolis their original?
Michael Palaiologos also fought against duchies in Hellas & the 300 knights of John de La Roche, as did Xerxes the Great against the 300 of Leonidas: Have many medieval biographies been mixed, as might have happened to the mentioned protagonists?
The researchers of the New Chronology described the Macedonian Empire as a duplicate of the Ottoman Empire, in that context the mentioned Baylonian Empire then being the Latin Empire, which also might have partially been duplicated as following dynasties:
- Hohenstaufen, emperors in the Holy Roman Empire
- Justinian, emperors in the Eastern Roman Empire
Both ultimately lasted for about a millenium, in accordance with the biblical kingdom in the book of Revelation: Do the first three kingdoms in the book of Daniel rather represent internal conflict within the Tartarian Empire?
The last kingdom then probably refers to the hidden Illuminati Empire: Is our yuga actually Satan's Little Season, as described in the book of Revelation?
