There are two adjacent archaeological mounds on the southwest side of present-day Sirsa, but archaeologists have not excavated them; therefore, the origins of the settlement at Sirsa remain unknown. However, some isolated discoveries have been made at the Sirsa mounds. The oldest find is a terracotta toy wheel, discovered in 1988, that archaeologists believe dates back to the Iron Age
Painted Grey Ware culture ( 1200-600 BCE). Four terracotta figures, including three depicting women and one depicting a tree (possibly a
kalpataru motif), are dated to roughly the time of the
Maurya and
Shunga dynasties. Numerous copper coins of the
Yaudheya and
Kushan periods have been found at Sirsa, along with various terracotta objects. These include a statue of the Buddha, a 0.6-m-tall sculpture of the goddess
Ganga on
her mount, a
mukhalinga depicting
Shiva, a figure of an elephant with a man and woman riding on top, and various others. Three gold coins from the
Gupta Empire (one depicting
Samudragupta and an unnamed queen consort, one depicting
Chandragupta II, and one of
Kumaragupta I) have also been found at Sirsa, along with numerous terracotta objects. the surviving part records the construction of a brick temple to Shiva by a
Pāśupata acharya named Nīlakaṇṭha. ==Geography==
