Idaikadar
Idaikadar (इडैकाडर), also romanized as Edaikadar or Idaikaadar, is a Tamil Siddhar counted among the eighteen Siddhars of the Tamil tradition. He is remembered in tradition as a master of weather prediction and astrological lore, and legend credits him with foreknowledge of, and survival through, a great deluge.
Tradition
Siddhar chronology is traditional rather than historical, and no independent records establish Idaikadar’s dates or biography. The name is popularly linked with a herdsman’s calling, and stories describe him as a humble practitioner who attained siddhi through devotion and yoga. The best-known legend relates that, foreseeing a catastrophic flood, he gathered provisions and took refuge on a hill, emerging after the waters receded to restore order among the survivors. Astrological and weather-lore verses circulate in the Siddha corpus under his name, though such attributions reflect lineage practice rather than documented authorship.
Teachings/Contributions
The material attributed to Idaikadar belongs to the Siddha engagement with cosmology and practical knowledge: seasonal prediction, planetary lore, and readings of natural signs. In Siddha thought, such knowledge is treated as an outcome of disciplined yoga and refined perception rather than of speculation, and it served agricultural and communal life.
Legacy
Idaikadar appears in encyclopedic lists of the eighteen Siddhars, including the Abithana Chintamani, and is also counted in navagraha-associated lists of Siddhars, where he is linked with Mercury. Sites remembered in connection with him receive local veneration.
