Taprobane is the name of a legendary island in the Indian Ocean, first mentioned by the Greek historical writer Onesicritus (c.360-290 BC). Although it is generally accepted to be the island of Ceylon, now Sri Lanka(d), there are dissenting voices such as that of Dhani Irwanto, who insists(a) that Taprobane is to be identified with the Indonesian island of Kalimantan (formerly Borneo), where he also locates Atlantis(b) and the Garden of Eden(c). Irwanto argues against Sumatra being Taprobone, an idea supported by some, such as Arysio Santos who also identified Atlantis as Taprobane.
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 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 it 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.(d)
Irwanto also claims that the biblical Garden of Eden and the legendary island of Taprobane were situated on the island of Kilimantan. 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 details in Ptolemy’s description with a place in western Sumatra called Tanjungemas renowned for its gold mines in the ancient times.
