carlos IV de bohemia - emperador carlos iv - corona de san wenceslao - historia de republica checa - historia de praga - san wenceslao i de bohemia

Each nation has its own particular treasures, so considered for their symbolic and patrimonial value rather than for the superficial monetary value they may have (which is often invaluable).

armaduras permitian movimientos agiles-armaduras de placas-edad media- jean le maingre boucicault-ciencia hiistorica-arqueologia

It is overwhelming to see medieval knights in the movies, loaded with their heavy plate armor and fighting to the death in some crude battle. Canned in kilos of steel, they could at best move around like clumsy robots, right? Well, it’s time to abandon this distressing vision, because these armors were made to provide … Read more

Social panic is a great excuse, a subterfuge used by cowards to avoid disclosing sensitive information. Data that, if known, rather than generating collective fear, would help to save lives.

1990 was a tremendously turbulent year for Madrid and, more specifically, for one of its neighborhoods: Cerro Belmonte.

Thus, the first … Read more

Because of this peculiarity, they look like creatures out of some disturbed mind, but they are very real, both they and their bloody “weepings”. They do not “weep” blood because they have seen something horrifying, but because it is an extremely curious defense mechanism.

Types of snakes according to their fangs

vibora-serpiente cascabel-serpiente solenoglifa-colmillo-veneno-tipos de serpiente-denticion serpientes

Snakes have often been associated with evil, either for cultural reasons or, directly, because of our survival instinct. We fear and respect them and the venom they use to hunt and defend themselves.
