Georges Dumézil
According to Varro and Georges Dumézil Furrina was a goddess of springs. Her name would be related to the Indo-European root *bhr-u-n, Sanskrit " bhurvan", indicating the moving or bubbling of water, cognate to Gothic "brunna" ("spring"), Latin "fervēre", from *fruur &gt; furr by metathesis of the vowel, meaning to bubble or boil. Compare English "fervent", "effervescent" and Latin "defruutum" ("boiled wine").
