It is quite true that, strictly speaking, the forms with Th-d, are Low-
German, and those with D-t, High-German, but before we trust ourselves to
this division for historical purposes, we must remember three facts: (1)
that Proper Names frequently defy Grimm's Law; (2) that in High-German
MSS. much depends on the locality in which they are written; (3) that
High-German is not in the strict sense of the word a corruption of Low-
German, and, at all events, not, as Grimm supposed, chronologically
posterior to Low-German, but that the two are parallel dialects, like
Doric and Aeolic, the Low-German being represented by the earliest
literary documents, Gothic and Saxon, the High-German asserting its
literary presence later, not much before the eighth century, but
afterwards maintaining its literary and political supremacy from the time
of Charlemagne to the present day.

When Theodoric married Odeflede, the daughter of Childebert, and a sister
of Chlodwig, I have little doubt that, at the court of Chlodwig or
Clovis, his royal brother-in-law was spoken of in conversation as
Dioterih, although in official documents, and in the history of Gregory
of Tours, he appears under his classical name of Theodoricus, in
Jornandes Theodericus. Those who, with Grimm {3}, admit a transition of
Low into High-German, and deny that the change of Gothic _Th_ into High-
German _D_ took place before the sixth or seventh century, will find it
difficult to account, in the first century, for the name of Deudorix, a
German captive, the nephew of Melo the Sigambrian, mentioned by Strabo
{4}. In the oldest German poem in which the name of Dietrich occurs, the
song of Hildebrand and Hadebrand, written down in the beginning of the
ninth century {5}, we find both forms, the Low-German _Theotrih_, and the
High-German _Deotrih_, used side by side.
