Baldursbrá (baldurs-brá), the complexion, or facial appearance, of our beloved sun-god. In English eye of day. Beautiful.
I do not know why some Margarita took Baldurs place. Some conversion, I suggest. But once we hear Baldursbrá we will use that term.
(–pron.-brá as –brau, not bra–),
Baldursbrá grows wild in Iceland, always close to the sea on sandy coast/beach.
