National Geographic piece about Delphi

Pythia - The Delphic Oracle with laurel leaf

Nat Geo has a fine story this month about Delphi, the navel of the Earth -- worth a look given that The Eumenides, when we get to it, opens with a long speech of the Pythia, followed by the appearance of Apollo. The article echoes the opening of that play, though it has a variant on the genealogy of the presiding deities of the site:

. . . this impressive spot in central Greece (about 100 miles northwest of Athens) was originally sacred to Gaea, mother goddess of the earth, who placed her son Python, a serpent, as a guard for Delphi and its oracle. Apollo, god of light and music, slew the serpent and took over the site for himself. Priestesses who served Apollo there were called the “Pythia,” named in honor of Gaea’s vanquished son. Throughout the classical world spread the belief that these priestesses channeled prophecies from Apollo himself. (Read about the science behind the Delphic Oracle's prophetic powers.)  NatGeo

The opening of The Eumenides offers its own genealogy of the site, beginning with the striking description of the Earth as πρωτόμαντιν - the first prophet:


πρῶτον μὲν εὐχῇ τῇδε πρεσβεύω θεῶν 
τὴν πρωτόμαντιν Γαῖαν: ἐκ δὲ τῆς Θέμιν, 
ἣ δὴ τὸ μητρὸς δευτέρα τόδ᾽ ἕζετο 
μαντεῖον, ὡς λόγος τις: ἐν δὲ τῷ τρίτῳ 
5λάχει, θελούσης, οὐδὲ πρὸς βίαν τινός, 
Τιτανὶς ἄλλη παῖς Χθονὸς καθέζετο, 
Φοίβη: δίδωσι δ᾽ ἣ γενέθλιον δόσιν 
Φοίβῳ: τὸ Φοίβης δ᾽ ὄνομ᾽ ἔχει παρώνυμον. 
λιπὼν δὲ λίμνην Δηλίαν τε χοιράδα, 
10κέλσας ἐπ᾽ ἀκτὰς ναυπόρους τὰς Παλλάδος, 
ἐς τήνδε γαῖαν ἦλθε Παρνησοῦ θ᾽ ἕδρας. 
πέμπουσι δ᾽ αὐτὸν καὶ σεβίζουσιν μέγα 
κελευθοποιοὶ παῖδες Ἡφαίστου, χθόνα 
ἀνήμερον τιθέντες ἡμερωμένην. 
15μολόντα δ᾽ αὐτὸν κάρτα τιμαλφεῖ λεώς, 
Δελφός τε χώρας τῆσδε πρυμνήτης ἄναξ. 
τέχνης δέ νιν Ζεὺς ἔνθεον κτίσας φρένα 
ἵζει τέταρτον τοῖσδε μάντιν ἐν θρόνοις: 
Διὸς προφήτης δ᾽ ἐστὶ Λοξίας πατρός. 

The Priestess of Pythian Apollo

First, in this prayer of mine, I give the place of highest honor among the gods to the first prophet, Earth; and after her to Themis, for she was the second to take this oracular seat of her mother, as legend tells. And in the third allotment, with Themis' consent and not by force, [5] another Titan, child of Earth, Phoebe, took her seat here. She gave it as a birthday gift to Phoebus, who has his name from Phoebe. Leaving the lake¹and ridge of Delos, he landed on Pallas' ship-frequented shores, [10] and came to this region and the dwelling places on Parnassus. The children of Hephaistos,²road-builders taming the wildness of the untamed land, escorted him with mighty reverence. And at his arrival, the people [15] and Delphus, helmsman and lord of this land, made a great celebration for him. Zeus inspired his heart with prophetic skill and established him as the fourth prophet on this throne; but Loxias is the spokesman of Zeus, his father.

Göbekli Tepe

National Geo has a great cover story this month about the world's oldest temple, dating back some 11,600 years, being excavated in Turkey

We used to think agriculture gave rise to cities and later to writing, art, and religion. Now the world’s oldest temple suggests the urge to worship sparked civilization.

Known as Göbekli Tepe (pronounced Guh-behk-LEE TEH-peh), the site is vaguely reminiscent of Stonehenge, except that Göbekli Tepe was built much earlier and is made not from roughly hewn blocks but from cleanly carved limestone pillars splashed with bas-reliefs of animals—a cavalcade of gazelles, snakes, foxes, scorpions, and ferocious wild boars. The assemblage was built some 11,600 years ago, seven millennia before the Great Pyramid of Giza. It contains the oldest known temple. Indeed, Göbekli Tepe is the oldest known example of monumental architecture—the first structure human beings put together that was bigger and more complicated than a hut. When these pillars were erected, so far as we know, nothing of comparable scale existed in the world.
