In Celtic polytheism, Belisama (epigraphically Bηλησαμα) was a goddess worshipped in Gaul. She is identified with Minerva in the interpretatio romana.
The etymology of her name has been taken to translate to "brightest one", i.e. containing a superlative suffix -isama attached to the root bel "bright"; based on this she has also been speculatively claimed as companion of Belenus, whose name seems to contain the same root. But the root bel has also (for either deity) been interpreted differently, e.g. as bel "strong".
A Gaulish inscription found at Vaison-la-Romaine in Provence (RIG G-172) shows that a nemeton was dedicated to her:
The identification with Minerva in Gallo-Roman religion is established in a Latin inscription from Saint-Lizier (anciently Consoranni), Ariège department (CIL XIII, 8):
The French toponyms Beleymas and Bellême (found in the Dordogne and Orne departments, respectively) are based on the theonym.
The presence of the goddess in Britain is more difficult to establish. Based on Ptolemy listing a "Belisama estuary",River Ribble in England seems to have been known by the name Belisama in Roman times.
You say you want out
I know what you mean
I call you 'black bird'
I call you 'dark queen'
The isolation I put you into
Is your protection and safety too
In your eyes, in your wings
There is hunger for skies above high
And I know, and you know
That you could never fly
Have you ever seen the daylight?
Black bird fly
Have you ever seen the rainbow?
Black bird fly
Do you wanna see the moonlight?
Black bird fly
Do you wanna see the rainbow?
Black bird fly
You say I'm crazy
I'm doing strange things
You pine within walls
Although you've got wings
But I know, and you know
That the sunshine's too bright for your eyes
And I know, really know
That this world is too cruel
So think twice
One night, one day
You'll make me cry, you'll fly away
One day, one night
You'll leave me watching your last flight...
