This book offers a comprehensive review and reassessment of the classical sources describing the cryptographic Spartan device known as the scytale. Challenging the view promoted by modern historians of cryptography which look at the scytale as a simple and impractical 'stick', Diepenbroek argues for the scytale's deserved status as a vehicle for secret communication in the ancient world. By way of comparison, Diepenbroek demonstrates that the cryptographic principles employed in the Spartan scytale show an encryption and coding system that is no less complex than some 20th-century transposition ciphers. The result is that, contrary to the accepted point of view, scytale encryption is as complex and secure as other known ancient ciphers. Drawing on salient comparisons with a selection of modern transposition ciphers (and their historical predecessors), the reader is provided with a detailed overview and analysis of the surviving classical sources that similarly reveal the potential of the scytale as an actual cryptographic and steganographic tool in ancient Sparta in order to illustrate the relative sophistication of the Spartan scytale as a practical device for secret communication. This helps to establish the conceptual basis that the scytale would, in theory, have offered its ancient users a secure method for secret communication over long distances.

Para todo gobernante, como para todo jefe militar, es imprescindible conocer las circunstancias concernientes a sus antagonistas y adversarios (reales o potenciales), con el fin de neutralizar cualquier amenaza y afianzarse en el poder. Sin esa información, las probabilidades de que un gobierno sea derrocado, o de que un general sufra una severa derrota, aumentan de forma exponencial. De ahí que las actividades y servicios de inteligencia hayan sido una constante a lo largo de la historia.A pesar de la importancia fundamental de este fenómeno, su existencia ha sido a menudo soslayada en lo que respecta a las sociedades del pasado. Sea por la dificultad que entraña la frecuente escasez de fuentes, por el temor a pecar de anacronismo o debido a inconscientes prejuicios idealistas, manuales y monografías acostumbran a negligir el tratamiento del papel desempeñado por las actividades de espionaje y contraespionaje en la Antigüedad. El presente volumen, fruto de la colaboración de un nutrido grupo de especialistas de varios países y coordinado por Fernando Bermejo-Rubio, cubre esa laguna, examinando con atención un factor que contribuye a obtener una visión más lúcida y realista del funcionamiento de las sociedades pretéritas. Articulado en cuatro partes –Oriente, Grecia, Roma y Antigüedad Tardía–, el libro constituye la primera obra colectiva dedicada íntegramente al análisis de esta fascinante temática en el mundo antiguo.

La historia total de la ciudad griega que puso de rodillas a sus enemigos en los campos de batalla y se ganó la fama de amar la virtud por encima de todo lo demás.
Esparta es la guerra y la virtud, pero también un gran misterio histórico que la propaganda de sus enemigos y el mito creado por sus admiradores han terminado de emborronar.
El catedrático César Fornis reconstruye con una infinidad de fuentes y valiéndose de la arqueología la épica aventura de una potencia militar envuelta en una guerra casi continuada desde su nacimiento como entidad política independiente en el siglo VIII a.C. hasta su pervivencia como una especie de parque temático de las glorias pasadas en época romana.
Las páginas de esta monumental obra exponen sus numerosas guerras, su particular monarquía de dos cabezas, sus cultos religiosos y una educación extrema que curtía el cuerpo y la mente de sus ciudadanos soldados.

"Lawmaking and Adjudication in Archaic Greece" re-evaluates central aspects of the genesis and application of laws in the communities of archaic Greece, including the structure and function of legislative bodies, the composition of the courts, the administration of justice and the use and abuse of legal norms and procedures by litigants in the courts and everyday settings. Combining a detailed analysis of epigraphical and literary evidence and the application of a model of interpretation borrowed from cultural analyses of law, this book argues that far from being monolithic creations of archaic polities that unilaterally informed social life, archaic legal systems can be more appropriately viewed as ideologically polyvalent and socially complex.It includes legal norms and the administration of justice articulated associations with divine and secular authority but also incorporated, mainly in their reception and application by average citizens, discourses of utility and resistance that actively contributed in the composition of social relations.
