Timna revisited : egyptian chronology and the copper mines of the southern Arabah

This article studies the chronology of the New Kingdom Egyptian copper mining in the southern Arabah valley, and particularly Timna, traditionally dated in the 13th– 12th centuries BCE. a reassessment is made of the local archaeological evidence and especially of the findings of the Hejazi Qurayya pottery in archaeological assemblages of the southern Levant. It is argued that the chronology of the New Kingdom activities at Timna needs a revision towards lower dates.

Bronze and iron weapons from Luristan

The 30,000 km2 province of Luristan is situated in western Iran and encompasses the upper valleys of the Zagros Mountains. Even today, local tribesmen inhabit Luristan with their settlement patterns similar to ancient times. Several scientific excavations in the Luristan region have uncovered evidence that this particular region was a major attraction for human settlements from the Paleolithic era onwards. In Ancient Iran, the existence of rich mines together with discoveries made by innovative and inventive artisans spurred the growth of the metalworking culture as an art and a skill among early human communities in Ancient Iran. The art of Luristan can be described as the art of nomadic herdsmen and horsemen with an emphasis on the crafting of small, easily portable objects, among these a number of bronze daggers, swords and other weapons. Throughout its history, Luristan was never an ethnic or political entity because Luristan has been occupied by various tribes and races, throughout its history. Next to Elamites, other tribes who inhabited Luristan were the Hurrians, Lullubians, Kutians, and Kassites. As local tribesmen of Luristan were illiterate, information about their history can only be partially reconstructed from the literature of their southern neighbors: the Elamites and Babylonians. Luristan smiths made weapons for both civilizations. The region was later invaded by Assyrians and finally the Iranians settled the area and absorbed the local tribes. Following an accidental find by the local inhabitants in Luristan in 1928 CE, a number of unlawful diggings reveal a number of metal objects made of bronze and iron that showed a high level of craftsmanship. These objects were offered for sale on the art market with fancy names to hide their origin. The subsequent scientific excavations several decades after the initial discovery provided fascinating information about the culture of Luristan. The metalworking art of Luristan spans a time period from the third millennium BC to the Iron Age. The artifacts from Luristan seem to possess many unique and distinctive qualities, and are especially noteworthy for the apparently endless, intricate diversity and detail that they characteristically depict. The bronze artifacts found in or attributed to Luristan can be each be classed under five separate heads: a) arms and armor, including swords, dirks, daggers, axes, mace heads, spearheads, shields, quiver plaques, protective bronze girdles, helmets; b) implements related to horsemanship, including decorative or ornamental objects for horses as well as bits and snaffles; c) items for personal adornment and hygiene, including anklets, bangles, bracelets, finger rings, earrings and tweezers; d) ceremonial and ritual objects, including talismans, idols, pins, anthropomorphic and zoomorphic figurines; and e) utilitarian objects comprising various vessels and tools, including beakers, bowls and jugs. The scope of this article is limited to a discussion of the bronze and iron weapons made in Luristan. The techniques used for making bronze weapons in Luristan included: casting with open molds, casting with close molds, and casting with lost wax process. For metal sheets used for quiver plaques and bronze protective belts, the hammering technique was used. Edged weapons made in Luristan can be classified into: a) daggers, dirks, and swords with tangs; b) daggers, dirks, and swords with flanges; and c) daggers, dirks, and swords with cast-on hilts. Next to bronze, iron was also used for making weapons such as the characteristic weapon from this area, the iron mask sword.

La abstracción formal y la validación del razonamiento inductivo

Resumen: Suele admitirse que uno de los problemas pendientes, al menos desde Hume, en la teoría de la ciencia es la justificación crítica de los procesos inductivos, que son los que siguen las ciencias experimentales, como son las ciencias naturales. Frente a las ineficaces explicaciones aportadas por el empirismo o neopositivismo, así como por los racionalismos o idealismos, que son radicalmente incapaces para resolver el problema, nosotros presentamos la respuesta del realismo aristotélico, basada en el correcto concepto de abstracción formal, ignorado o malentendido incluso por muchos aristotélicos tanto antiguos como modernos. La respuesta consiste, en suma, en ver que el término del proceso inductivo, en cuanto llega a conclusiones universales a partir de lo particular, debe estar mediado por un proceso previo de abstracción de la forma, bien entendida, en lo mismo concreto y particular. Ello permite ver que la conclusión universal no desborda las premisas, que es el problema clásico de la epagogé aristotélica.

Por qué es necesario un método en la decisión bioética

Resumen: Las resoluciones de un comité de Bioética influyen directamente en la vida de las personas pero son superadoras de la instancia particular. Tal vez por causa de su misma importancia social, el debate bioético contemporáneo se ha escapado del dominio de los especialistas y ha llegado a comprometer y apasionar al público en general. Éste intuye que en esa discusión se juega la sociabilidad humana y aun la misma noción de Hombre. La sola reunión del comité experto no procura una respuesta. Para el comité de Bioética, la verdad no es evidente a primera vista, sino que debe descubrirla. Para ello es necesario el método para seguir tras la verdad de las cosas y, aunque nada asegura la infalibilidad, contribuye a evitar errores morales.
