After Pausanias, Descriptions of Greece, Boiotia IX:8 adapted from Jones & Ormerod, 1918 trans.  

The Town of Potniai

  [1] About ten stades distant south from Thebai, on the other side of the Asopus River, is the town of Potniai, which hosts a grove sacred to Demeter and Persephone. Statues of these daimones stand where the river flows past the town. On the day of the vernal equinox, the citizens let loose young pigs into the place they call “the halls.” These pigs reappear, exactly one year later, on the other side of Hellas in the center of Dodona.   [2] Here also is a temple of Dionysos the Goat-Slayer. Once, long ago, when the Dionysian followers were sacrificing to their daimon, they grew so violent with wine that they killed their own priest. Immediately after the murder, the town was visited by a pestilence. The Delphic oracle said that to cure the plague, the town must sacrifice a boy in the bloom of youth. This was done each year to keep the pestilence at bay until, after a few years, the daimon allowed the townsfolk to substitute a goat in place of a boy. Nearby this temple is a well whose water drives mares permanently mad, although all else can drink with no ill effect.   [3] On the way from Potniai to Thebai, on the right side of the road, is a small enclosure with pillars in it. On this spot, the earth opened to receive Amphiaraus, King of Argos, during the War of the Seven. Birds do not sit upon these pillars, nor will a beast, tame or wild, graze on the grass that grows there.  

Seven Gates of Thebai

  [4] Around the ancient wall of Thebai were seven gates, and these remain today. One got its name from Elektra, the sister of Kadmos. Another, the Proitidian, from a native of Thebai called Proitus, whose date and lineage I could not determine. The Neistan gate, some say, got its name for the last of the harp's strings, the nete, which Amphion invented it at this gate. I have also heard that the son of Zethus, the brother of Amphion, was named Neis, and that it's after him that this gate was called.   [5] The namesake of the Krenaian gate is unknown to all, but the Hypsistan is named for a sanctuary of Zeus Hypsistus, or Most High. Next after these gates is the one called Ogygian, named after the most ancient King Ogyges, who founded his city on the site that would become Thebai. The dragon of Ares destroyed the city of Ogygia to its last structure, while survivors fled to Attike. Next is the Homoloid gate, whose name is the most recent.   [6] The name Homoloid is derived from the when the Thebans were beaten in battle by the Argives near Glisas, during the War of the Epigoni. Most of the defeated withdrew along with Laodamas, the son of Eteokles, to the Kadmaian outpost in far-distant Illyria. One group abandoned the long journey, and turned aside to Thessaly where they seized Homole, the most fertile and best-watered of the Thessalian mountains.   [7] When these Thebans were recalled to their original homes by Thersander, the son of Polyneikes, they renamed the gate, through which they passed on their return, the Homoloid gate after Homole. The entry into Thebai from Plataia is by the Elektran gate, and at this, so they say, arrogant Kapaneus, the Argive son of Hipponous and Astynome, was struck by lightning during the War of the Seven, as he was making a more furious attack upon the fortifications.
