Reality Check

References and mentions of things that seem like they don't belong in Ancient Greece, even the fantasy version of Ancient Greece that our heroes inhabit! (Also see: Pop Culture References and Greekisms.)

1.02 Between Friends

• Cheiron treats Hercules with acupuncture, a form of treatment that can be traced as far back as the 1st millennium BCE in China. The first Chinese medical text that describes acupuncture is the Yellow Emperor's Classic of Internal Medicine, which was compiled around 305-204 BCE.

1.04 Herc and Seek

• Cratus says, "You left us for this? Schoolbooks and playing warrior.". The first bound book was described by 1st-century AD Roman poet Martial (source), which is a long time after Hercules would have lived. Cratus should have said "Schoolscrolls"!

1.06 Teachers Pests

• At the beginning of the episode, Jason is seen putting away boxing gloves. Did boxing exist back then? According to Wikipedia, the earliest evidence for fist fighting with any kind of gloves can be found on Minoan Crete (c. 1500–900 BC), and on Sardinia, if we consider the boxing statues of Prama mountains (c. 2000–1000 BC) (source). So yes, it's quite possible that the cadets trained with boxing gloves!
• Fiducius claims he wants the scrolls put away in strict alphabetical order. But alphabetization was probably not used until at least the 1st century BC! (source)
• Jason says that he dropped most of the 'F's. But the letter F wasn't in the Greek Alphabet (source). The closest character to the English "ph" sound would probably be the character 'Phi' (Φ φ).

1.08 Keeping Up With the Jasons

• When Jason is trying to hurry them up, Lilith says "Relax, it's okay, we've still got a few minutes." The minute as a unit of time was invented by ancient Babalonians around 5,000 years ago (source). Even if that information was being used in Greece, what device was Lilith using to tell the time?

1.11 Battle Lines I

• Iolaus says, "It's Friday. End of the school week." The earliest attestation of a seven day week associated with heavenly luminaries are from Vettius Valens, an astrologer writing ca 170 AD in his Anthologiarum. The order was Sun, Moon, Ares, Hermes, Zeus, Aphrodite, and Cronos. From Greece the planetary week names passed to the Romans, and from Latin to other languages of southern and western Europe, and to other languages later influenced by them. The word 'Friday' comes from the Old English Frīgedæg (pronounced [fri.je.dæg] or [fri.je.dæj]), meaning the day of the Anglo-Saxon goddess Fríge (source). So it's more likely that Iolaus would have called it Aphroditeday!

1.14 No Way Out

• Hercules says, "You know, it wouldn't've taken a brain surgeon to figure out 'my brother' was behind all this." You would think brain surgery wouldn't have existed back then, but apparently there is ample evidence of brain surgery dating back all the way to the Neolithic (late Stone Age) period. (source)

1.16 Down and Out in Academy Hills

• In this ep, Kora makes a new drink with special beans from Ethiopia. But the story of Kaldi, the 9th-century Ethiopian goatherd who discovered coffee, did not appear in writing until 1671 AD and is probably apocryphal. From Ethiopia, coffee was said to have spread to Egypt and Yemen. The earliest credible evidence of either coffee drinking or knowledge of the coffee tree appears in the middle of the fifteenth century, in the Sufi monasteries of Yemen (source), so it's doubtful that she could have found anyone selling the beans back in Ancient Greece.

1.19 Lure of the Lyre

• Bacchus was the Roman god of wine. His Greek equivalent was Dionysus. And Dionysus had a human form - he did not have the head of an animal.

1.28 In Your Dreams

• Ceres was the Roman Goddess of Agriculture. Her Greek equivalent was Demeter.
