The only significant depiction of the divinity of Shiva is found in the form of a four-armed portrayal of Bhairav on a temple shaft near the entrance of the temple, within the mandapa. It is the first religious image encountered upon visiting the temple. He is adorned with a serpent necklace, but other identifying attributes have deteriorated over time. His heavily bejewelled naked body reveals his genitalia.
The representation of a dancing Shiva or Natesha is depicted in the niche on the cornice above the pillar of the mandapa (pillared hall) of the Bisaldeo Temple.
On one of the pillars in the mahamandapa (pillared hall) of the Bisaldeo Temple is a short inscription which mentions the name of ‘Jogi Achpantadhaja’ or ‘Yogi Achintyadhvaja'.
The ceiling of the central hall or the mahamandapa (pillared hall) is of the nabhichchhanda variety, characterized by a band of five concentric overlapping circles decorated with lotus petals and other floral designs. The top of the ceiling is embellished with a full-blown lotus, complete with a padmakesara (stem-like) pendant.
In 1872, A.C.L. Carlleyle visited Bisalpur and provided the first known archaeological report on its temples under the supervision of Alexander Cunningham, the first Director General of the Archaeological Survey of India (ASI). His report includes a fully measured plan of the Bisaldeo Temple that was lithographed at the Surveyor General’s office in 1877.
This inscription, dated 1187 CE (VS 1244), was composed during the reign of Prithivaraja Chauhan and records the donation of two sword handles to the mandapa (pillared hall) of the temple of Sri Gokarna in Vigrahapura (Bisalpur). It is inscribed on a pillar in the mahamandapa (pillared hall) alongside other informative inscriptions. The inscription underscores the strong association between the city of Vigrahapura (Bisalpur) and King Vigraharaja IV, also known as Bisaldeo, who is celebrated in oral accounts and medieval bardic accounts as the temple’s patron. The mention of the city’s name in the solidifies this connection. Furthermore, it establishes the original name of the temple as the temple of Gokarna, derived from the name of the shivalinga housed within a nearby cave in the village.
The square portion of the shaft of the pillar in the mahamandapa (pillared hall) is carved with a niche on each of its four faces. Within these niches are figure sculptures depicting various scenes: some portray apsaras (celestial damsels) engaged in activities such as playing musical instruments, dancing, or playing with a ball. Others depict yogis (ascetics) or royal figures engaged in acts of veneration. One niche notably showcases a sculpture of a four-armed Bhairav.
