Which Script of Which Ancient Civilization Has Not Been Deciphered?

Script is a crucial element of any civilization. It is a medium through which one can communicate, document and preserve information for future generations. Ancient civilizations had their own unique scripts that were used for various purposes such as religious texts, historical accounts, trade, and commerce.

However, there are some scripts that have not been deciphered yet. Despite the advancements in technology and the efforts of scholars and linguists, these scripts remain a mystery to us. Let’s take a look at some of these undeciphered scripts.

Indus Valley Script:

The Indus Valley Civilization was one of the earliest civilizations in the world, flourishing between 2600 BCE to 1900 BCE in the northwestern regions of South Asia. The script used by this civilization is known as the Indus Valley Script or Harappan Script.

Despite being discovered in 1924 and thousands of inscriptions being found on seals, pottery, and other objects, this script has not been deciphered yet. Scholars believe that it might be a logo-syllabic script where each symbol represents both a word and a syllable.

Etruscan Script:

The Etruscan Civilization flourished in central Italy between the 8th to 3rd centuries BCE. The Etruscan script was written from right to left and consisted of about 26 letters.

Despite being relatively well-documented with over 13,000 inscriptions found on various artifacts such as pottery, walls, tombs etc., this script has not been deciphered yet. Scholars believe that it might be related to either Indo-European or Semitic languages.

Rongorongo Script:

Rongorongo is a hieroglyphic script used by the Rapa Nui people of Easter Island between the 13th and 16th centuries CE. It consists of about 120 characters, written in reverse-boustrophedon style (alternating directions).

Despite being the only script used by the people of Easter Island, it has not been deciphered yet. Scholars believe that it might be a mnemonic device rather than a fully-fledged writing system.

Linear A Script:

The Minoan Civilization flourished on the island of Crete between 2700 BCE to 1450 BCE. The Linear A script was used by this civilization for religious and administrative purposes.

Despite being discovered in 1900 and thousands of inscriptions being found on various objects such as pottery, tablets etc. Scholars believe that it might be related to the Greek language.


These undeciphered scripts are a testament to the complexity and diversity of ancient civilizations. Despite our best efforts, we have not been able to unlock their secrets yet. However, with advancements in technology and new discoveries being made every day, we might be able to decipher these scripts in the future.
