Hurstgra
Hurstgra is also one of the many Batavi Goddesses who has been almost forgotten in history. Similar to Exomna and Haeva, only one altar stone has been discovered that mentions the name of the Goddess. This altar stone in particular was discovered near Kapel Avezaath, the Netherlands. The stone is dated back to somewhere between 150-250AD.
The inscription on the stone reads: "For the goddess Hurstaga, according to her order, Valerius Silvester, municipal councilor of (the) Municipium der Bataven, founded (this altar), and with good reason."
Unfortunately we do not have a single clue who Hurstgra and what her exact role was in the Batavi pantheon. It is however very likely that all these native Dutch deities like Hurstgra, Nehalennia, Exomna, Haeva and a few others are actually much older than the Germanic culture itself. They might have been worshipped by the ancient Dutch people before even the Celts spread their influence in the low countries.
In case you were wondering why all these altar stones end with 'for good reason' is because they were basically seen as a contract. One would ask a favour of a particular deity and if that favour was granted, you had to give an offering in return. Most likely the common people offered an animal or food but the wealthier people, especially those influenced by Roman culture or working with the Romans, made these type of altar stones as an offering to the deity to thank him/her for the favour that had been granted.
It is too bad that we only have these altar stones with their names on them but at least we know of their existence. If the Batavi people wouldn't have copied Roman ways of life, we would have never known about these Gods and they would have been forever lost in time.
