Nusasura: The Atlantis Island?

<Bahasa Indonesia>

A research by Dhani Irwanto, 1 June 2018

In 2017, I visited an island in the middle of the Java Sea, namely the Bawean Island, to deliver a presentation about the island’s connection with Atlantis. I spent a few days there, wandering around the tiny island to observe and talk to every resident I met. There is an interesting thing that I got when talking with them. Some people told a legend about the existence of a mysterious island located on the north of the island, in the middle of the Java Sea, which is now drowned. They also told about the frequent occurrence of fishing boats or vessels that ran aground or lost when sailing near the mysterious island.

After returning from the island, I thought about opening up the old maps composed by geographers from the sixteenth and seventeenth centuries. After I observed, many maps show the existence of an island located in the northeast of the Bawean Island, with various names such as Nusasua, Nisasira, Nusasira and Nisaira (see attached maps). Then I translated the names into Nusasura, which means “the shark islands” or “the islands of bravery” in the Austronesian language group. Is Nusasura the Island of Atlantis?

Slide1Slide2Slide3Slide4Slide5Slide6Slide7

In a research published in 2015, I undertook a hypothesis of the island of Atlantis, where there is the capital city of the kingdom of Atlantis, that is located on the northeast of the Bawean Island. The island is now drowned and overgrown by a coral reef named Gosong Gia or Annie Florence Reef. This coral reef was mapped in detail using multi-beam echosounder some time ago. From the pattern of the coral reef, the structure of the city and its dimensions narrated by Plato can still be seen. The location of the coral reef is more or less the same as the Nusasura shown on the above maps. Please note that the authors of the maps were informed by European sailors who sailed in the Java Sea. The sailors obtained the information about the islands in the Java Sea from the local residents or sailors, who probably also told of the mysterious island and then it was described by the European sailors.

Furthermore, I also observed the ancient records contained in Egypt. From here I obtained a word that sounds like Nusasura, Neserser. In the mythology of the Ancient Egyptians, the island and the lake of Neserser, “the island and the lake of flames” (in the volcanic region) where Osiris and Thoth came from, is often mentioned in their myths. As described in the Papyrus of Nu (in the Book of Dead), the myth tells that Osiris has his throne on the island of Neserser in the center of six or seven concentric circles with a gate at each and they are all in the “lake” of Neserser. The concentric circles were built for Ra by the dwellers of the lake. Thoth had his lands around the lake and he visited Osiris on the island. There was a great flood in the lake of Neserser and somehow these circles of Ra became hidden.

As written in many tomb texts from the Middle Kingdom and the Second Intermediate Periods in the Ancient Egypt, in the concepts of the divinities and the deceased, the Neserser island is a heaven-like place, a place where judgement is passed and the deceased is reborn equipped with a status (god or common being). The Hetep-fields is a kind of paradise under the supervision of the god Hetep with whom the deceased identifies himself, and where he leads the happy life reserved for the privileged. In the concept, Osiris, Horus and Thoth were given the status of gods or ancestral divinities.

The description of Neserser is resemblant to the story of Atlantis.

  1. Six or seven concentric circles were built for Ra on the island of Neserser, conforming to the Atlantis’ four circles of lands (including the central land) and three circles of water, built by the god Poseidon.
  2. Either Osiris or Atlas have their thrones on the central lands.
  3. The lake of Neserser is conforming to the almost closed sea around the Atlantis capital island. Plato describes the sea as a water with a mouth to the outer sea, thus arbitrarily can be called a lake. As described above, I made a hypothesis in 2015 that the sea is the ancient Java Sea where it had only one outlet.
  4. There was a great flood in the lake of Neserser which devastated the island of Neserser, and then it was hidden. This is also in conformity with the descriptions about the destruction of Atlantis.

Again, a sound-like word of Nusasura, Nisir, is also found on the Mesopotamian clay tablets, the name of a sea where Gilgamesh sets out on a series of journeys to search for his ancestor Utnapishtim that has been given eternal life. In 2016, I made a hypothesis that the Epic of Gilgamesh fit the conditions in Indonesia, from the descriptions such as full of noisy birds and cicadas, and monkeys scream and yell in the trees.

Detecting Ancient Coastal Civilizations from Coral Reefs

A research by Dhani Irwanto, 3 February 2016

Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps. Reefs grow best in warm, shallow, clear, sunny and agitated waters.

Coral reefs begin to form when free-swimming coral larvae attach to submerged hard surfaces. As the corals grow and expand, reefs take on one of three major characteristic structures – fringing, barrier or atoll. Fringing reefs, which are the most common, project directly from the hard surfaces, forming reefs and expand in horizontal and vertical directions. Barrier reefs also project, but at a greater distance. If a fringing reef forms around a rocky island that subsides completely below sea level while the coral continues to grow upward, an atoll forms.

The Sunda shelf was exposed during the Ice Age, the most recent glacial period occurring during the last years of the Pleistocene, from approximately 110,000 to 12,000 years ago. It was in the Sundaland that man first found the ideal climatic conditions for development, and it was there that he invented farming, structure building, seafaring and civilization from 70,000 years ago. People of these civilizations were dependent on water for their mobilizations, so coastal areas were the most suitable places to live and then communities were formed there. They used stones and woods to build houses and other buildings since these materials were abundant in the region.

The Ice Age waned during the period 14,000 – 7,000 years ago that accompanied by sea level rise – as much as 130 m. The costal communities then moved to adjust the changing coastlines and remnants of their buildings were left sank under the sea. Finding the most suitable places to grow, coral reefs were formed on these buildings.

Based on the data of coral reefs and bathymetric maps, the author identifies the probable sites and ages of the ancient civilizations, as shown on the attached map. Note that not all of the coral reef sites were ancient civilizations because coral reefs could form on natural hard surfaces as well.

According to Plato’s narrative, Atlantis ended at around 11,600 years ago. Based on the above study, the location of the capital city of Atlantis is expected at one of the very ancient civilization sites shown on the map. Plato also wrote that the capital city of Atlantis at Solon’s time had been covered by a coral reef so it was not navigable.

Coral Reef

<Bahasa Indonesia>

A research by Dhani Irwanto, 18 August 2015

From Plato’s Timaeus Section 25d: “For which reason the sea in those parts is impassable and impenetrable, because there is a shoal of mud in the way; and this was caused by the subsidence of the island.

“A shoal of mud” is the generally published translation of the Ancient Greek phrase “πηλοῦ κάρτα βραχέος” written by Plato. “κάρτα βραχέος” is not syntactically good and it is not found in any manuscript; “πηλός” is masculine and is the antecedent of the relative pronoun; “κατὰ βραχέος”, for its turn, is adverbial. The simple meanings of the words are: πηλοῦ for “clay” or “mud”, κάρτα for “very” and βραχέος for “shoal” or “reef”. Other alternative translation is “the clay that exists in large quantity there and of the small depth” (Lopes, 2011).

The author translated πηλοῦ κάρτα βραχέος into “coral reef” for the reason that this sea formation is scarce in the Mediterranean so that the Greeks and the Egyptians did not own the term. The Mediterranean no longer shelters the great coral reefs that thrived 60 million years ago. This is due to millennia of climactic and oceanographic changes. Today, there are only a few species of colonial anthozoans that have the capacity to create the coral reefs. In 2010, the exploration vessel Nautilus has discovered for the first time an area of reefs with deep-sea corals in the Mediterranean, offshore of Israel. This area apparently stretches over a few kilometers, 700 meters under the surface and some 30 – 40 km off the coast.

In the above Plato’s account, the citadel of Atlantis was impassable and impenetrable at the time of Solon (about 600 BC) because of the growth of a coral reef caused by sea level rise during the Ice Age (“subsidence of the island”). The present condition of the hypothesized site is that there is a coral reef identified by the sailors as Gosong Gia or Annie Florence Reef, a coral reef described as small in extent and dries at low water.

Atlantis Island

Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps. Reefs grow best in warm, shallow, clear, sunny and agitated waters.

Often called “rainforests of the sea”, shallow coral reefs form some of the most diverse ecosystems on Earth. They occupy less than 0.1% of the world’s ocean surface, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, molluscs, worms, crustaceans, echinoderms, sponges, tunicates and other cnidarians. Paradoxically, coral reefs flourish even though they are surrounded by ocean waters that provide few nutrients. They are most commonly found at shallow depths in tropical waters, but deep water and cold water corals also exist on smaller scales in other areas.

Coral reefs begin to form when free-swimming coral larvae attach to submerged rocks or other hard surfaces along the edges of islands or continents. As the corals grow and expand, reefs take on one of three major characteristic structures – fringing, barrier or atoll. Fringing reefs, which are the most common, project seaward directly from the shore, forming borders along the shoreline and surrounding islands. Barrier reefs also border shorelines, but at a greater distance. They are separated from their adjacent land mass by a lagoon of open, often deep water. If a fringing reef forms around a volcanic island that subsides completely below sea level while the coral continues to grow upward, an atoll forms. Atolls are usually circular or oval, with a central lagoon. Parts of the reef platform may emerge as one or more islands, and gaps in the reef provide access to the central lagoon (Lalli and Parsons, 1995; Levinton, 1995; Sumich, 1996 as cited by NOAA).

NOAA coral04b_480

In addition to being some of the most beautiful and biologically diverse habitats in the ocean, barrier reefs and atolls also are some of the oldest. With growth rates of 0.3 to 2 centimeters per year for massive corals, and up to 10 centimeters per year for branching corals, it can take up to 10,000 years for a coral reef to form from a group of larvae (Barnes, 1987 as cited by NOAA). Depending on their size, barrier reefs and atolls can take from 100,000 to 30,000,000 years to fully form.

The citadel of Atlantis consisted of hard surfaces so that a coral reef began to form in a while after its submergence, grows and expands as commonly found at shallow depths in tropical waters. Any underwater explorations may not find the citadel unless they made investigations under the reef.

The rate of seawater rise in the Last Glacial Period is in average 0.6 centimeter per year. Because of the warm water at the hypothesized site, the growth rate of the coral reef is expectedly higher than the rate of seawater rise. Accordingly, the vertical growth rate of the coral reef at the site is parallel to the seawater rise.

The sea level kept rising until about 6,000 years ago. Corals grew on the solid structures, along with sedimentation and other processes. There is an existing coral reef named Gosong Gia or Annie Florence Reef at a site in the Java Sea believed to be the location of the capital city. From an unpublished sonar survey of the site by a sponsor team, the top of the reef and the surrounding sea bed are about 10 and 55 meters below the average sea level, respectively. The city structures such as the hill, the circular wall, the circular channel and the bridge are still apparent from the patterns of the corals with exactly the same dimensions as those described by Plato. The depth of the surrounding sea here exactly coincides the land level about 11,600 years ago before the sea level rise. However, further investigations are required to confirm.
