fawr iawn gais,
Deg aruthr erioed a gerais.

The word _Aruthr_, though much used, in the sense you take it, seems not
proper here; yet Dr. Davies translates it _Mirus_. I cannot think but
the original import of the word is _terrible_; and they cannot say in
English of a woman, she is _terribly fair_. _Rhuthr_, from whence
_Aruthr_ is compounded, I dare say had that sense, at least:--

"Y cythraul accw ruthrwas."

W. LLEYN.

Deg wawr erioed a gerais,

may do as well, and sounds better.

A roist ofal i'm calon,
A brath o hiraeth i'm bron:
Ni wyr un ar a anwyd
A roist o gur, os teg wyd;
Enwa anhunedd yn henaint
A yr wyn fyth yr un faint.

The first line of the last couplet is too long, and I should write both
thus:

Enwa'n hunedd yn henaint
E yr wyn fyth yr un faint.

Again:

Cyrchaf, ac ni fynnaf au,
I dir angov drwy angau.

The last couplet is a beautiful expression; but it hath too much sweet in
it; what our poets call _Eisiau Cyfnewid Bogail_. _Ang_, _ang_, is a
fault, which our musicians term _too many_ _concords_; and therefore they
mix discords in music, to make it more agreeable to the ear. So the
rhetoricians call the same fault in their science, _Caniad y gog_.
Therefore, suppose you would turn it thus:

O dir ing af drwy angau.

Again:

Lle bo dyfnaf yr afon,
Ar fy hynt yr af i hon,
Oni roi, Gwen eurog wedd,
Drwy gariad ryw drugaredd.

_Eurog wedd_ is no great compliment to a fair woman; for _Gwen_, a
Flavia, loves to be called white; and the last line hath _gar_--_gar_,
therefore I would write thus, or the like:

Oni roi, Gwen ir ei gwedd,
Yn gywrain, ryw drugaredd.

But I do not like _ir ei gwedd_.

Af i graig fwyaf o gred
Y mor, i gael ymwared,
Ag o'r graig fawr i'r eigion
Dygaf gyrch i dyrch y don--

An excellent expression--

Ag o'r don egr hyd annwfn
Af ar y dafl i for dwfn.

Here is a charming opening for you, to describe the country you go to,
and the wonders of the deep; and something like the following lines might
be inserted:

Lle mae'r morfil friwfil fron,
A'r enwog _forforwynian_,

To proceed:

A fynno Gwen ysplennydd
Yn ddiau o'm rhwymau 'n rhydd,
Ni chaf gur, ni chaf garu
Na phoen gwn, na hoffi 'n gu;
Ni roddaf gam i dramwy,
I gred i'th ymweled mwy:
