Etymology of the
Meaning of the baby name PERAHTA.
Teutonic name meaning "the bright, the glorious." It
is the same as English Bertha.
Also see Perchtha.
... A being
similar to Holda, or the same under another name, makes her appearance
precisely in those Upper German regions where Holda leaves off, in
Swabia, in Alsace, in Switzerland, in Bavaria and Austria. She is
called frau Berchte,
i.e., in OHG. Perahta, the bright, luminous, glorious (as Holda
produces the glittering snow): by the very meaning of the word a
benign and gladdening influence, yet she is now rarely represented as
such; as a rule, the awe-inspiring side is brought into prominence, and
she appears as a grim bugbear to frighten children... (Teutonic
Mythology, Grimm-Stallybrass, 1882)
