Magusanos is a Celtic god worshipped in Gaul and Britain; he is likely to have been considered a protective deity, and possibly a psychopomp.
Magusanos was sometimes identified by the Romans with their god Hercules by way of the interpretatio romana.
Magusanos received votive and dedicatory offerings from his worshippers; otherwise little is known of the specifics of his cult.
The origin of Magusanos is uncertain, even as to whether it is of Celtic or Germanic origin. If Celtic it could be derived from the Proto-Celtic *magos or “field”; if Germanic it may have come from the Proto-Indo-European *moghtis or “might, power.”
It has also been suggested that Magusanos may contain both Celtic and Germanic elements; in this case deriving from the Proto-Germanic *magu or “boy” and the Proto-Celtic *senos or “old.” With this combination, the name Magusanos could translate to “old youth,” which could describe the usual Gaulish representation of Hercules, shown as possessing the strengths of both youth and age.
Magusanos had a particular center of worship in the region of Batavia, in what is now the Netherlands and north-eastern Germany,
