It is still a mystery how Antikythera vessel went down at the Mediterranean sea.

Being the largest trading ship sailed in the first century BC, Antikythera still holds an unsolved mystery that maritime archaeologists have yet to reveal - how the shipwreck could lie on the seabed, 52 meters deep, CNN reported.

A team of archaeologists dived and found a treasure on Antikythera shipwreck - a man's skeleton

The international team of archaeologists went into the seafloor of a remote area in Mediterranean. Diving in the gravesite, 52 meters below the surface level and with a few hand swipes, the team revealed the long bones before finally found the skull - believed to be 2,000 years old.

Archaeologists are excited with the finding as it means a step closer to unveil the shipwreck mystery - what caused the vessel to sink.

The human remains is named Pamphilos - which means friend to everyone. Now, the scientists will search for potential DNA recovery in the remains. Hannes Schroeder from Denmarks' Natural History Museum will be responsible to seek such information which could reveal genetic ancestry. HuffingtonPost noted that the experts will likely confirm the gender, eye color and ethnicity.

Antikythera shipwreck holds some of the most important artifacts in history during the Roman reign - including the world's oldest computer - a device similar to a clock which was used to predict 'celestial events'.

Researchers are confident that the vessel brought trading goods after the discovery of gold jewelry, marbles and glassware in 1900 excavation.

With the human's skull discovery, researchers hope to get an insight of the Antikythera mechanism aside from understanding the passengers on board, ScienceAlert reported.
