|The unicorn always has this object in front of it. There are at least five theories about this object. Mackay and Marshall thought it was the feeding trough or "manger" still seen in Sindh today. There is work
connecting it to contemporary offering stands used in central India
today. Mackay also guessed that it could have been a cage for birds or
insects, or an incense burner. A fifth, more recent theory suggests that
the object may have been the filter used to extract the intoxicating
Soma drink described in the Rg Veda.
