The meaning is unknown, it is the rune sign for 'P' and for the number '13', sometimes the meaning is given as 'bread' or 'earth' or 'stone'
Rind (Rinda, Rindr, Rindur) is a giantess and an earth- and fertility goddess in the Nordic mythology. She is the daughter of Billing, one of Odin's wives and the mother of Vali.
I couldn't find anything about the meaning of her name. An Old Norse word which looks similar is 'rinda' / 'hrinda' which means 'to get rid of something', 'to throw off something'. But I don't know if the name belongs to that word...
