Sirocco

Il est bien précoce cette année, ce vent d'Afrique,
autrement l'héraut bienvenu du printemps, maintenant
voulant nous arracher de nos agréables somnolances de février.
Sa langue sèche et chaude, fait chanter les feuilles
d'automne encore endormies sur les chênes.
Les vaches aux champs sans rosée, reniflent deux fois
cet étrange air des sables, trouvant note et constat.
Les glaçons encore suspendus des toits, fondent par étonnement,
puis hésitent de goutter, autant ils n'y croient pas.

Die alte Kirche

Bei einer sonntäglichen Wanderung
Hab' ich erstmals zu sehen versucht
Was lag, an der verborgenen Steigung,
Da drüben, zwischen Kamm und Schlucht.

Ein verlassenes Dorf, so hart verkleinert
Durch vergessene Seuchen und Kriege,
Es entsprach nicht mehr dem ganzen Wert,
Der vollen Größe, seiner alten Kirche.

Was für eine Zeugin früherer Zeiten,
Vor Jahrhunderten sorgsam errichtet,
Die schöne Hüterin vergangener Menschen
War mit teuren Graniten ausgestattet.

Der schmale Eingang lag am Westen
Nach der Regel der damaligen Zeit.
Ganz leise betrat ich die stillen Stufen,
Immer höher in die Vergangenheit.

Aus Eichenholz bestand die offene Tür.
Sie hat den Stürmen all widerstanden,
Und bot ihre Schwelle ohne Gebühr,
Doch jetzt, ohne Gläubige zu empfangen.

Hoch oben gab's noch die kleine Rosette.
Ihre Gläser strahlten vor bunten Farben.
Und vom Glockenturm hingen die alten Seile,
Nunmehr, ohne Messe zu verkünden.

Ein Baustein trug noch das Maurers Zeichen,
Hier für die Ewigkeit stolz gemeißelt
An solch einem Kunstwerk der Seligen,
Von einer Bedeutung nie bezweifelt.

Links im Vorraum stand die Skulptur noch heil
Einer Jungfrau Maria mit Rosen in Hand.
So kunstvoll verfeinert nach Bildhauers Beil,
Noch strahlte das Gesicht vor sanftem Verstand.

Auf uralten Steinen trat ich nach vorn
Zwischen leeren Bänken einst voll besetzt.
Beim Altar spielte ein Cherub sein Horn
Neben zwei Kerzen, gebrannt bis zuletzt.

Im Fresko der Heiligen noch gut erhalten,
Dort wo das Sonnenlicht hereinströmte,
Gelang dem Maler die Weisheit der Mienen,
Als nur der Glaube das Wissen schaffte.

Noch glänzte die Orgel, fortan doch stumm.
Sodann, ich dachte : muss jetzt nach Haus.
Deswegen schaut' ich, noch Mal herum,
Und ging durch die Tür wieder hinaus.

So verließ ich die Kirche, bald mir weit hinter,
Und stieg ruhig ab, zu dem bewohnten Tal.
Sie stand noch offen für andere Besucher
Mit anderen Gedanken, ein anderes Mal.

El Presente Alternativo

Esa mañana me quedaba dormido,
si no casi, porque me encontraba
entre lo despierto y el sueño, detenido
en un instante que no adelantaba.

No podía, sí no quería, dejar este estado
suspendido, cuya causa aún no la sabía.
Sólo aprovechaba ese momento parado
en donde un flujo del tiempo no había.

Supe que el hilo del tiempo no es uno,
que el presente no es un punto que se mueva,
sino un plano entero en un espacio alguno
que me brindaba una dimension nueva.

Desde este plano temporal podía ver hacia
donde si no cuando están futuro y pasado,
el uno que no ocurre, el otro que no cambia,
en ese momento perpetuo del tiempo fijado.

Qué quedaba en este suelo del presente,
sino pasado más abajo y futuro más arriba?
De pie traté de ver detrás luego delante
otro hoy, otro tiempo, una hora alternativa.

Con el pie toqué el plano a la izquierda,
si no a la derecha, sólo para probar el suelo
de esta terra incognita y incierta
que me invitaba a un mundo paralelo.

Entonces hice no un paso sino un saltito,
y pisé este plano del presente alternativo,
entre lo que sería y lo que habría sido,
en medio de lo subjetivo y lo relativo.

Vi lo que yo habría podido, si no querido,
hacer en ese espacio-tiempo cristalizado.
Vi adonde habría ido, y como habría vivido.
Andaba con seguro en ese momento helado.

Vi lo que yo podría ser, si no elegir,
según la corriente del tiempo caprichosa.
Vi adonde podría ir, y cuando podría vivir,
en esa extrañeza todo maravillosa.

Sin embargo, por nostalgia si no añoranza,
quise volverme a mi propio tiempo familiar.
Así traté de recobrarlo con esperanza,
pero en reconocerlo, no me pude confiar.

Había demasiado presentes muy semejantes.
Cómo el presente mío podría encontrarse?
Cómo volver a donde si no cuando estuve antes?
De prisa - el tiempo iba a reanudarse!

Por fin me agarré a un presente cualquier.
Era si no el justo, al menos un parecido.
Aún no sé si estoy de vuelta como ayer,
pero no importa.  Me gusta de haber ido.

Ode to Rex

Rise up Great Lizard!
Resist the throes of death.
Wistful is your demise,
A reign too quick cut short.
Your once yellow bright sun,
Has been veiled with iron,
By a rock of unplanet kindred,
Which fell to splash on Earth.

Live Great Lizard live!
The ones below still fear you.
Yours is a world of steam,
Of swamp and sand and palm.
At the first glow of that intruder,
Your eyes began to wet;
A stately life of loft and grace
Had come to pass in night.

Speak Great Lizard speak!
Your voice is loud and strong.
A wisdom of eons lived
Is locked within your heart.
Look quietly and understand,
Your kingdom and its lore,
Ere the dust strike you down,
And leave your soul to pass.

But alas your fate is frozen.
The hegira cannot be sought.
Only your bones of fossils future
Will last to tell the plot.
Be peaceful then, Great Lizard;
Yours is glory not forgotten.
Rest ye upon your sandy hearth,
With eyes turned toward the stars.

Autumn 1982

Les oiseaux se cachent pour mourir

Les oiseaux se cachent pour mourir
voulant fuir l'oeil pesant d'autrui
qu'il comprenne mieux ou pire
cet inconnu voyage de nuit.

Le papillon au vol boiteux, éphémère
embrasse les fleurs aux odeurs vives,
mais suite aux amours nuptiaux en l'air,
pressent-il la fin qui arrive?

Le vieux chat aux trousses des proies
est encore satisfait de son allure
mais une fois qu'elle ralentira
pensera-t-il aux jours futurs?

Le dauphin au parcours sage et long
lorsqu'il voit une vie qui se perd
je voudrais bien savoir à fond
ce qu'il en dit aux confrères.

Avant de quitter ce monde trop beau
l'homme sait bien qu'il mourra
mais quant aux autres animaux,
songent-ils à l'au-delà?
