In the Andean valleys of Colombia, people began carving large sculptures around 2,000 years ago. Who made these fantastical statues, hybrids of humans and Amazonian animals? Very little is known, but archaeologists are making some surprising discoveries!

Si tenemos un presidente de rodillas ante EE. UU., no es un defensor, es un comerciante de la patria. ¿Qué le ocultan al país el presidente y el canciller? Se niegan a darme la información.

Ha pasado un mes desde los acuerdos firmados en Barranquilla con EE. UU. y nadie, absolutamente nadie, ni en el Senado ni en el país, conoce qué se entregó, qué se negoció, qué gana Colombia o qué pierde. Los memorandos no son reservados, son de obligatorio conocimiento y debate público.

In a desert 1,000 years ago, the Chimú people built a city that would become the biggest in the Americas. Chan Chan was an engineering marvel, and some 12,000 artisans lived there. At last, Peru’s great urban experiment has archaeologists’ attention.

La razón científica detrás de perdonar 70 veces 7.

Desde los tiempos de Jesús hemos llevado este consejo como algo superficial. Hoy la ciencia nos indica la verdad detrás de perdonar 70 veces 7.

Las palabras de Jesús nunca pasarán. Una prueba más de Dios está entre nosotros y su amor nos quiere llevar a ser y estar mejor.

The Egyptian Blue - more than just a colour...

Around 200 years ago, chemist and inventor Sir Humphry Davy went to the ruins of Titus’ baths in Rome. There, ‘amongst some rubbish, [he] found several large lumps of a deep blue frit’. Soon after, Davy found the same material on a pot in Pompeii. He realised that he had rediscovered the material ‘of which the manufacture is said to have been anciently established at Alexandria’, the first synthetic pigment, Egyptian blue. The tale of Egyptian blue’s discovery, ‘disappearance’ and rediscovery is a fascinating one, and illustrates beautifully how art can act as a facilitator for the advancement of chemistry.

For the ancient Egyptians, blue was a very important colour. It was associated with the sky and the river Nile, and thus came to represent the universe, creation and fertility. However, in ancient times, only the earth colours (colours provided by the surface soil) were used as pigments – blue could not be easily obtained by Egyptian artists. Indeed, the only natural source of blue was the rare and expensive mineral lapis lazuli, which was mined in what is now Afghanistan. However, at around 2600 BC, Egyptian blue enters the historical record, and use of the pigment gradually spread across the ancient world as far as Mesopotamia and the Roman empire before being apparently lost in the dark ages. Sadly no Egyptian recipe for the pigment remains, but Vitruvius, a Roman writer in the 1st century BC, stated that sand, copper (from a mineral such as azurite or malachite) and natron (a naturally occurring mixture of sodium compounds, including sodium carbonate) were the ingredients. Modern experiments show that Egyptian blue (chemical formula: CaCuSi4O10) can be obtained by heating these chemicals to 800–900°C with the addition of lime, a calcium-containing material, which must have been present in the ancient method, probably as an impurity in the sand.

Whether its discovery came about by design or chance, the synthesis of Egyptian blue was a seriously impressive accomplishment. Achieving necessary temperature control for successful reaction would have been a major challenge, as indeed would the correct addition of oxygen. Another testament to the skill of Egyptian chemists is consistency of the pigment throughout history. Composition in artworks such as the mastaba (tombs) of Mereruka, from the Old Kingdom (2600–2100 BC), is almost exactly the same as that found in a mummy coffin dating from the Greco-Roman period (330 BC–AD 400), and there are other examples dated between these two that show similar compositions.

In an exciting development for chemists and artists, it was reported in 2009 that Egyptian blue shows exceptional luminescence in the near-infrared region.3 This means that the pigment can be easily detected in a completely non-destructive fashion simply by illuminating ancient works of art with near-infrared radiation. The luminescence is so strong that the presence of minute amounts of Egyptian blue can be detected even when no blue colour is visible to the naked eye. The British Museum was able to use this technique to provide the first proof that the Elgin Marbles had once been painted, finding the pigment on several sculptures from the Parthenon.

Roma non smette mai di incantare il mondo.
Siamo sul Colle Oppio, nelle gallerie sotterranee delle Terme di Traiano, e qui sotto c’è una meraviglia unica al mondo: la “Città dipinta”.
È un affresco straordinario, una vera e propria città vista dall’alto, con le mura, le torri e gli edifici rappresentati in prospettiva. Ed è ancora più incredibile pensare che è stato realizzato quasi duemila anni fa, in epoca neroniana o flavia, quindi prima ancora delle Terme di Traiano. E poi c’è un altro capolavoro: il mosaico della “Musa e del Filosofo”, che faceva parte della decorazione di una grande sala affacciata su un ninfeo.
Sulle pareti, i mosaici riproducono addirittura una grande scenografia teatrale, con statue e personaggi reali. Insomma, qui sotto Roma continua a sorprenderci. E ogni scavo aggiunge un pezzo alla storia straordinaria della nostra città.
Ma la sorpresa non finisce qui.
Perché anche sopra abbiamo completamente riqualificato il giardino e la grande esedra delle Terme di Traiano.
Abbiamo realizzato una nuova cavea per accogliere il pubblico e valorizzare questo luogo con piccoli concerti, conferenze ed eventi. Ci sono una nuova illuminazione, il nuovo manto erboso e nuovi percorsi pedonali.

L’apertura al pubblico inizierà in via sperimentale, solo per alcune giornate e in piccoli gruppi, per poter monitorare e valutare l’impatto della presenza antropica sulla conservazione delle delicate opere. Per il mese di settembre, a partire da sabato 12 e domenica 13, la galleria sotterranea e l’esedra saranno aperte al pubblico nel fine settimana con visite guidate gratuite, in lingua italiana e su prenotazione. Poi, a partire dal 2 ottobre, le visite si svolgeranno dal venerdì alla domenica. Per ciascuna giornata sono previsti sei turni, alle ore 10.00, 11.00, 12.00, 13.00, 14.00 e 15.00 per un massimo di 15 partecipanti per fascia oraria. Prenotazione consigliata allo 060608.

🏺 Hace más de 2.000 años, comunidades prehispánicas de Antioquia ya dominaban el fuego con una precisión asombrosa: lograban cremar cuerpos y fabricar cerámica a temperaturas de hasta 900°C, ¡sin hornos modernos ni electricidad!

🔬 Así lo revelan dos investigaciones de la #UdeA, lideradas por Laura Valentina Toro —Antropología— y Elizabeth Jiménez —Maestría en Física—, quienes analizaron urnas cinerarias del estilo Marrón Inciso que resguarda el Museo Universitario —Muua—.

💡 Los hallazgos muestran que estas urnas no eran objetos reutilizados: se elaboraban exclusivamente para rituales funerarios complejos, en los que la técnica, el simbolismo y el cuidado del cuerpo iban de la mano.
