Vrddha Garga

Garga, also known as Vṛddha Garga ("Garga the Elder"), was an ancient Indian scholar of jyotisha. Several Sanskrit-language jyotiḥśāstra works - covering topics such as astrology, astronomy, and divination - are attributed to him. These works were written over several centuries, and are obviously not the work of a single author. Modern scholars generally date the oldest of these works - Gargiya-jyotisha - to the 1st century CE, although the source materials for these works may be much older.
