New Delhi, 18 April

Manuscripts of Bhagavad Gita and Bharat Muni's Natyashastra are among 74 new documentary heritage collections that have been added to UNESCO's Memory of the World Register.

Entries on scientific revolution, women's contribution to history and major milestones of multilateralism from 72 countries and four international organisations are included in the register, according to UNESCO.

The register consists of books, manuscripts, maps, photographs, sound or video recordings as a documentary heritage of humanity.

The development comes on World Heritage Day on 18 April.

Prime Minister Narendra Modi, in a post on X, on Friday described the inscriptions as "a proud moment for every Indian across the world".

"The inclusion of the Gita and Natyashastra in UNESCO's Memory of the World Register is a global recognition of our timeless wisdom and rich culture. The Gita and Natyashastra have nurtured civilisation, and consciousness for centuries. Their insights continue to inspire the world," he said.

Preserved at the Bhandarkar Oriental Research Institute and codified around the 2nd century BC, the Natyashastra of Bharat Muni is "an epitome of the Natyaveda, an oral body of knowledge of performing art containing 36,000 verses known as the Gandharvaveda," the UNESCO said in its citation list about the new inscriptions.

Bharat Muni makes a "groundbreaking statement in Natyashastra, asserting that 'no meaning can blossom forth without rasa', a profound contribution to world literature," it said.

The Natyashastra embodies a comprehensive set of rules that define natya (drama), abhinaya (performance), rasa (aesthetic experience), bhava (emotion), sangita (music), among others, thus articulating the character of Indian theatre, poetics, aesthetics, dance and music.

The "Manuscript collection of Bhagavadgita: ancient samgraha-grantha of Indian thought with worldwide readership and influence" also now finds a place in the coveted UNESCO register.

"The Bhagavadgita, containing 700 verses in 18 chapters, is embedded within the Bhismaparva of the epic Mahabharata. It takes the form of a dialogue between Krishna and Arjuna with armies lined up for the great war intended to free Arjuna of dejection (visada)," the citation read.

Bhagavad Gita is a central text in the continuous, cumulative ancient intellectual Indian tradition, synthesising various thought movements such as Vedic, Buddhist, Jain and Carvaka, it said.

"Due to its philosophical breadth and depth, the Bhagavadgita has been read for centuries across the globe and translated into many languages," the citation added.

Union Culture Minister Gajendra Singh Shekhawat also took to X on Friday saying this was a "historic moment for Bharat's civilisational heritage".

This global honour celebrates India's eternal wisdom and artistic genius, the minister said.

"These timeless works are more than literary treasures -- they are philosophical and aesthetic foundations that have shaped Bharat's worldview and the way we think, feel, live, and express. With this, we now have 14 inscriptions from our country on this international register," he posted and shared some images of the two texts.

On Thursday, UNESCO added 74 new documentary heritage collections to its Memory of the World Register, bringing the total number of inscribed collections to 570, the world body said.

Collections are added to the register by a decision of UNESCO's executive board, following the evaluation of nominations by an independent international advisory committee.

Among the newly inscribed collections, fourteen pertain to scientific documentary heritage.

Ithaf Al-Mahbub, submitted by Egypt, documents the Arab world's contributions to astronomy, planetary movement, celestial bodies, and astrological analysis during the first millennium of our era, UNESCO said.

The archives of Charles Darwin (United Kingdom), Friedrich Nietzsche (Germany), Wilhelm Conrad Roentgen (Germany) -- which contain the very first recorded X-ray photographs -- and Carlos Chagas (Brazil), a pioneer in disease research, have also been included.

Several collections document key moments in international cooperation, including the Geneva Conventions (1864-1949) and their protocols (1977-2005) (Switzerland), the Universal Declaration of Human Rights (United Nations), and the 1991 Windhoek Declaration (Namibia), a global reference for press freedom, the UNESCO said in the statement.

"Documentary heritage is an essential yet fragile element of the memory of the world. This is why UNESCO invests in safeguarding -- such as the libraries of Chinguetti in Mauritania or the archives of Amadou Hampate Ba in Cote d'Ivoire -- shares best practices and maintains this register that records the broadest threads of human history," UNESCO's Director-General Audrey Azoulay said.

The Permanent Delegation of India to UNESCO also acknowledged the inscriptions of ancient Indian texts on the Register and thanked UNESCO.
