Although of French origin, Lucien has much of 'oscense' (so born in Huesca); not in vain his works and his contact with 'Upper-Aragon' earth therefore credit it.
He is a pleasant writer and great walker (hiker) by the Aragonese Pyrenean, of whom he was an extraordinary publishing of its beauties. Very specially they were it those of Ordesa, valley that he knew in 1891.
Briet dedicated many of his writings to these subjects, that were gathered in three books by the Museum of the Pyrenees of Lourdes. Therefore, his works are remarkable on the Macizo de Marboré, Peña Montañesa. Sierra de Guara, desfiladero de Entremón, Gargantas del rio Vero, Valle de Vió, rio Flumen, El Salto de Roldán, Bielsa, diverse precipices and caves… and specially his book 'Beauties Upper-Aragón' ( Bellezas del Alto Aragón), that was published in Huesca in 1913, and of which several editings became, being first in 1977. In this book he describes his adventures by Ordesa, valley of the Ara river, Escuaín, Bielsa, Mascún, and he even mentions the Pyrenean spelunking scope of the limestone one.

Almost 90 years later, when its work is read, surprise so much the accurate one and detailed description of the places that it relates, as the graphical support of multitude of photographies of an excellent quality, considering which they are from principle of the last century.
