I have started some time ago to transform a Swiss legend from the Canton of Jura into a poem with rhyming couplets, because when reading it I realised that we have practically all the necessary vocabulary. I shall post it in bits and pieces as it is going to be fairly long.

Comments and corrections most welcome.

Yá andanéya fairi en ranner
palúrenna ar marintar carner
nu falmar hya mi haure felehtar
nurtala – queni sanner – harmantar,
tauri Sírenando nér i vehte
andave túrienwa ló melehte

Mólala lístan*
namba talyainen niquis
et i lotsello

Toiling bee
hammers with its feet a petal
out of the flower

*lístan: kenning for bee "honey-maker"

Talan lassea -
nu nelleo nén tinda
tuileo tuimar
cénar aurion naltar
i váner - i tuluvar

Leafy ground -
under brook's glinting water
Spring's buds
see reflections of days
those that went - those to come

Alve hrívesse
ingaryasse cucua
hára fanyasse

Elm in winter
on its top a dove
sits on a white cloud

aureo quenta
tecina certainen ló

I wonder if someone finds out what I have seen!

In dulci jubilo,
Lamyaina Iluo!

O Jesu parvule,
Nye láva lumbule.
A sutya indo-ninya,
O puer optime,
Mánalyainen ilya,
O princeps gloriae.

O Patris charitas!
O Nati lenitas!
Nánelme ilquen vanwa,
Per nostra crimina,
Men ánes tá voronwa
Coelorum gaudia.
|: Quanta gratia! :|

Ubi sunt gaudia?
Nómesse ui lá hyá,
Yasse Ainur lindar
Nova cantica,
Ar i Híni nandar
In regis curia.

Here is another experiment with a fixed form - a triolet.

I lóme melinye
rá ilyan ya calima
imbe Menel Cemenye.
I lóme melinye
yá silme *cirihtanye
ar tintanye licuma,
an i lóme melinye
rá ilyan ya calima.

Things that I like

I love the night
for all that is bright
between Heaven and Earth.
I love the night
when I reap the starlight
and kindle a candle,
for I love the night
for all that is bright.

And here is an English version also in Triolet form:

It may sound trite, but the night I love
for all that is fair and bright

Lasselanta en
mal hríve úva véna.
Hlarin hlusseya
yá lóri aunorir as
norolinde *nyarrinci

Autumn still
but winter is drawing near to us.
I hear his whisper
when dreams run away together with
lightly tripping mice.

*We do not seem to have a word for mouse, so I made the rat smaller !
A Tanka on a recurring event, when winter comes, some mice insist on putting to the test our hospitality :)

This a Hungarian folk-tale - I hope it is enjoyable.
