La historia de un peregrinaje más a través de un milenario camino. En el Año Mil, tras el fallecimiento de su marido, la condesa de Conquereuil emprende peregrinación a Santiago de Compostela desde la Bretaña francesa, para postrarse ante el Apóstol, recibir la indulgencia y pedirle que haga crecer a su hija pequeña, que es enana y que, a causa de su deformidad, ha sido rechazada por las gentes y hasta por su propio padre, pues la han creído endemoniada.

Culmina con este volumen la trilogía de poesía religiosa «Hombre y Dios». Para esta última antología se ha elegido Europa, incluyendo la del Este, aunque el «telón» impidió, durante un largo tiempo, la publicación de este tipo de poesía en algunos países.

Ahora ya, no. Miguel Ángel Pérez Oca lo ha hecho posible. En su esfuerzo encontró siempre la ayuda de los...

In contrast, they have advanced a policy of draconian budget cuts--austerity--to solve the financial crisis. We are told that we have all lived beyond our means and now need to tighten our belts. This view conveniently forgets where all that debt came from. Not from an orgy of government spending, but as the direct result of bailing out, recapitalizing, and adding liquidity to the broken banking system. Through these actions private...
