Dhani Irwanto (1962- ) is an Indonesian hydraulic engineer, who is the latest proponent of the Sundaland location for Atlantis, in his April 2015 book, Atlantis: The lost city is in the Java Sea. A review of his book online(a), shows quite clearly that the author has made a serious effort to match Plato’s narrative with his chosen location for Atlantis, namely off the southern coast of the island of Kalimantan in the Java Sea. Irwanto also uses his professional expertise to analyse Plato’s many references to the waterways of the Atlantean capital and its extensive plain. The review also includes a number of maps and video clips used to support Irwanto’s views.
Irwanto has also adopted(c) the 32-point checklist of dos Santos and expanded it to 60 points. He has now published a YouTube video supporting his theory(d). The first 30 pages of his book can be read online(f).
Irwanto also claims that the biblical Garden of Eden and the legendary island of Taprobane were situated on the island of Kalimantan*. In an extensive online(b) article in November 2015, he identified the Indonesian island of Sumatra as the land of Punt, which he thinks was also known as the Ophir referred to in the Old Testament (1 Kings 9.26 & 10.11).
In June 2017, Irwanto published an illustrated paper(e) on Aurea Chersonesus, referred to by Ptolemy in his 2nd century Geographia . Irwanto has matched the details in Ptolemy’s description with a place in western Sumatra called Tanjungemas renowned for its gold mines in ancient times.
On his website, since the publication of his book, Irwanto had continued to add a number of detailed articles that are of interest to students of Atlantology. One example came in late 2021, when he added an extensive paper entitled Decoding Plato’s Narrative to Find Atlantis, using a visual format, infographics(g) that is worth a look.
