Budha

Planet Indian astronomical observations of the planet Budha (Mercury) are recorded in several Sanskrit texts from the first millennium CE. These include the 5th century Aryabhatiya by Aryabhata, the 6th century the Romaka by Latadeva and Panca Siddhantika by Varahamihira, the 7th century Khandakhadyaka by Brahmagupta , and the 8th century Sisyadhivrddida by Lalla. The myth of the Tarakamaya War describes the events leading to his birth from Tara. Budha married Ila, with whom he had a son, King Pururavas.

One of the earliest mentions of Budha appears in the Vedic text Pancavimsa Brahmana. The deity also appears in other ancient texts such as the Shatapatha Brahmana though not in the context of astrology.

Calendar and Hindu astrology The word 'Budhavara' or Wednesday in the Hindu calendar derives from Budha. In Greco-Roman and other Indo-European calendars, "Wednesday" is also dedicated to the planet Mercury (for eg. "day of Odin").

Budha is part of the Navagraha (nine planetary deities) in the Hindu zodiac system, where he is considered benevolent, associated with an agile mind and memory. The role and importance of the Navagraha developed over time with various influences. Glorification of planetary bodies and their astrological significance appeared as early as the Vedic period and was recorded in the Vedas. The earliest known work of astrology in India is the Vedanga Jyotisha, which began to be compiled in the 14th century BCE. The classical planets, including Mercury, were referenced in the Atharvaveda around 1000 BCE.

The three nakshatras (lunar mansions) ruled by Budha are Ashlesha, Jyestha and Revathi .

The Navagraha system was furthered by developed through contributions from Western Asia, including Zoroastrian and Hellenistic influences. The Yavanajataka, (literally Science of the yavanas, referring to the Greeks) or Science of the Yavanas, was written by the Indo-Greek named "Yavaneshvara" ("Lord of the Greeks") under the rule of the Western Kshatrapa king Rudrakarman I. The Yavanajataka written in 120 CE, is often credited with standardizing Indian astrology. The Navagraha system continued to develop and culminated during the Shaka era under the Shaka (Scythian) people. Contributions by the Shaka people later became the basis of the Indian national calendar, also called the Shaka calendar.

The name Budha also forms the root for the word for Wednesday in many other Indian languages. In modern Hindi, Odia, Telugu, Bengali, Marathi, Urdu, Kannada and Gujarati, Wednesday is called Budhavara; in Tamil: Budhan kizhamai; in Malayalam: Budhanazhcha; in Thai: Wan Phut .

Iconography

According to Roshen Dalal, Budha's iconography depicts him as a benevolent male deity with green body, draped in yellow clothes, and holding a scimitar, a club, and a shield. He is shown riding a chariot drawn by eight yellow horses. In some illustrations, he has four arms and rides a lion; in the Budha Temple, he is depicted riding a lion.
