Mamuni Mayan (மாமுனி Māmuṉi meaning Brahmarishi Mayan, Sangakala Sirpachithan Mamuni Mayan, Mayamuni, Mayendran) is a culture hero character from Tamil Sangam literature (the Silappathikaram, Manimekalai, and Civaka Cintamani epics) and the founder of Vastu Shastra.
Mayan is credited with the authorship of the Mayamata Vastu Shastra as well as the Aintiram (Aindra, a school of grammar connected with the Tolkāppiyam). If there had been a grammatical treatise called Aintiram, it has been lost, but a text called Mayan's Aintiram dealing with Vastu Shastra was published by Sthapati in 1986, with the support of C. Aranganayakam, Tamil Nadu minister of education, and again in 1997 by the "Vaastu Vedic Research Foundation" with English commentary by S. P. Sabarathnam.
In 2006 Dr. V. Ganapati Sthapati asked Dr. Jessie Mercay, USA, to establish a small school - American University of Mayonic Science and Technology - in the US to teach authentic principles of Vaastu Shastra, Silpa Shastras and related texts including Mayan's Aintiram.
