Moonsorrow is a Finnish pagan metal band formed in Helsinki in 1995.
 Musically, the band incorporates elements of black metal and folk metal in their sound.
 The band call their sound "epic heathen metal" and try to distance themselves from the term "Viking metal".
 They have distanced themselves from other folk metal bands, emphasising that their music is pagan and spiritual and is challenging for its listeners, rather than happy or danceable.
 The band members have varying levels of pagan belief but they draw on pagan spirituality for lyrics and inspiration.

The Batavi were an ancient Germanic tribe that lived around the modern Dutch Rhine delta in the area that the Romans called Batavia, from the second half of the first century BC to the third century AD.
 The name is also applied to several military units employed by the Romans that were originally raised among the Batavi.
 The tribal name, probably a derivation from "batawjō" ("good island", from Germanic "bat-" "good, excellent," which is also in the English "better," and "awjō" "island, land near water"), refers to the region's fertility, today known as the "fruitbasket of the Netherlands" (the Betuwe).

 Pagan was later added for vocals and Marco played the drums.
 Furor Gallico have songs in both English and in Italian, the band members take alternating roles in who writes the lyrics and composes the music in either language.
 The song Curmisagios was even written in dialetto brianzolo, a lombard dialect spoken in the area of Brianza, in western Lombardy.
