Alfonso Caso e Ignacio Bernal, en su libro Urnas de Oaxaca, muestran que para los mayas y los zapotecas el murciélago era una deidad muy importante y que con frecuencia se le representaba con características humanas y nunca en una forma natural.

Smithsonian Returns Three Khmer Artifacts Thought Looted to Cambodia

NYT: Smithsonian Returns Three Khmer Artifacts Thought Looted to Cambodia

The objects were the first returned under a 2022 policy requiring the institution to weigh a wider range of factors, like plunder under colonial rule, when deciding to repatriate items.

No dudo en decir que es una obra que marca un hito en la epigrafía maya de Palenque, pues da información actualizada de todos los monumentos documentados hasta el momento, con magníficas fotografías y dibujos, acompañados de traducciones de los textos.

Landscape-wide cosmogram built by the early community of Aguada Fénix in southeastern Mesoamerica The cosmogram of Aguada Fénix built over the landscape between 1050 and 700 BCE rivaled the extents of later Mesoamerican cities.

🧵The cosmogram crowd are at it again. Sigh. Cool new site, Aguada Fenix, is interpreted by Takeshi Inomata et al as a big cosmogram. The article is here: science.org/doi/10.1126/..., with a journalism article in LiveScience here: livescience.com/archaeology/.... What's wrong with that? 1/6

Egypt’s Grand Museum Is Finally Open. Now, ‘We Need Our Stuff Back.’

For many Egyptians, the state-of-the art museum is a stage from which to renew demands that Egypt’s most iconic antiquities belong in their homeland — not the marble halls of European museums.

Mexique: la restitution de deux codex préhispaniques au cœur de la visite d'Emmanuel Macron Lors de la visite du président français Emmanuel Macron au Mexique vendredi 7 novembre, son homologue mexicaine Claudia Sheinbaum devrait évoquer le délicat sujet de la restitution de deux codex préhispaniques : le codex Azcatitlán, conservé à la Bibliothèque nationale de France, et le codex Borbonicus, qui se trouve à la bibliothèque de l'Assemblée nationale. Depuis 2024, les représentantes de la communauté Ñahñu au Mexique réclament officiellement la restitution du dernier.

This black-figure terracotta kantharos-rhyton has a sculpted donkey-head attachment and Dionysian figures around the body of the vessel. In fact, on the rear of the cup Dionysos is shown riding on an ithyphallic mule or donkey, so the head on the cup is Dionysos' own steed. The fun part is that when you grasp the cup by both handles and raise it to your mouth to drink, you look like you’re wearing a donkey mask, providing a great deal of chuckles from your fellow symposiasts.

This appears to be the earliest preserved Attic rhyton (a vessel for wine, frequently with animal head pouring spouts), and this rhyton-kantharos as a whole is a rare preserved example of an Athenian plastic vase with black-figure decoration. In design, the donkey's tall, outward-flaring ears are echoed by the kantharos' tall looping strap handles. In order to assemble this vase, the potter cut a hole in the kantharos' bowl and precisely inserted the donkey's head, thereby forming a dual-chambered wine vessel with a large capacity. But the resulting rhyton-kantharos is overweighted toward the donkey's head, which extends down so far that the donkey's lips set the vessel off kilter, and it rests unstably on the kantharos' foot. 

Greek, Attic, about 520-500 BCE, possibly found in Athens. Black-figure terracotta with some pigments (purple on the Dionysian figures and red inside the donkey's mouth).

Height: 21.59 cm (8.50 in.)
Diameter: 13.65 cm (5.37 in.)

How often can you say that you've seen a kantharos-rhyton? This cup has a bridled donkey head attachment, usually seen only on rhyta. It mirrors the donkey seen on the reverse of the cup, ridden by Dionysos. When you drank from this vessel, you looked like an ass! 🏺 1/

New Case: The Aubin Tonalamatl, contributed by Damien Huffer

In June 1982, Mexican attorney and journalist José Luis Castañeda del Valle entered the Bibliotheque Nationale in Paris using a false student ID and permits. He convinced curators that he was a student there to study the ancient text.
