We're told that Sally Jackson chose the name "Perseus" for Percy because he, pretty much alone of the great Greek heroes, got a reasonably happy ending. However, he also killed his grandfather (by accident); Percy, by comparison, is responsible for the defeat of Kronos, who is his grandfather.
An earlier example from the first book: the Perseus in Greek mythology killed Medusa because he was ordered to by Polydectes, a king. Polydectes was interested in Perseus' mother and wanted him out of the way so that he could force her to marry him. Perseus returned with Medusa's head and turned him to stone. Percy's abusive stepdad Gabe befalls the same fate.
Annabeth's Taking the Bullet in TLO. She was attacked by Ethan, a son of Nemesis. Nemesis was the spirit of retribution against hubris, something that Annabeth admits to.
If you look at it that way, Ethan and Nemesis even joining Kronos' side. Hubris is considered to be the fatal flaw of Zeus, after all. Then Ethan balances this out—while his mother still fights for the Titans, he turns and fights for the gods, against Kronos, who's ego is big enough to have its own gravity field. Really, for all the myths that were messed up in the books, Riordan was perfect with some of this stuff.
When ZoŽ dies in Titan's Curse, Artemis puts her spirit in the stars as a constellation. She has done this once before in the original myths...for Orion, her lover. Suddenly ZoŽ's devotion to Artemis gains a whole new level of meaning...
Actually, it's debated whether or not Orion was actually Artemis/Diana's lover, considering Artemis's schtick of being a perpetual maiden and all that jazz. At the very least, they were tight hunting partners.
There are four well known versions of the myth of Orion's death. Alpha) Zeus sent a giant scorpion, called Scorpio in Latin & Scorpios in Greek, because Orion was getting too close to Artemis. Beta) Apollo sent Scorpios for the same reason Zeus did. Gamma) Orion threatened to hunt all animals to extinction & Gaia sent Scorpios. Delta) Artemis realized that she was falling in love w/Orion, freaked out, and sent Scorpios.
In Book 4, Chiron makes a big deal about how only three people can go on a quest. However, by the end there are six, and none of them die. At first, I thought this was a Plot Hole or something. Then I realized: six is a multiple of three! Meaning the rule wasn't violated at all through their new knowledge of a certain bureaucratic loophole. Makes one wonder why they don't just send nine kids(3x3). Or twenty-seven(3^3).
Because having a bunch of demigods in a single place would collectively create a smell based neon sign declaring "Come eat me" to every monster in a ten mile radius.
Well, the original quest is actually only 4 people, they need new people to advance the plot.
Notice that Hades was absent from the winter solstice meeting in The Titan's Curse? He didn't want to draw attention to himself with Nico out there.
Surely you'd assume that demigod children would know about their divine origins - actually; a lot of gods probably try to keep this hush hush because when some people know it's not turned out well - I mean, Tantalus probably left a bad taste in a lot of mouths in Olympus (Especially Hera), Phaeton was allowed to drive the sun because his fellow kids didn't believe him, etc. Not to mention when mortals know that they were in love with a god, not all of them turned out that well. ( It's mentioned in "The Lost Hero" that Thalia and Jason's mom was...kinda screwed up in the head and Zeus didn't really help her that much, until he came around in his Roman aspect.) Naturally the kids have a right to know are told when they're old enough to handle it; and some mortals who do know about it are told because they can maturely handle it.
Thalia's last name is Grace. This seems innocuous at first, but I did some digging. Turns out there is another daughter of Zeus, also named Thalia, who is one of the Graces.
Goes farther than that. Thaleia, the muse, also a daughter of Zeus is sometimes translated as blooming and usually spelled in English as Thalia.
In the fourth book, Calypso says that she has always sent someone who can't stay, but in the original myth, Odysseus leaves because he is in love with someone else. Meanwhile, Percy is worrying about Annabeth...
It makes sense for Annabeth and her dad to live in such a high-military area as Jamestown, Virginia, with many universities nearby, since he is a professor of military history. And a lot of the Revolutionary War and Civil War happened in the area. Why he should move out to San Francisco makes no sense, but the Presidio there is also a former military installation.
Prometheus was right about the Battle of Manhattan being a reenactment of the Trojan War. However, he was wrong about which side was which
I saw it differently: the defenders in the Trojan War lost but despite the half-bloods heritage the kids aren't Greek, they're American, and America won its war of independence defending itself not by invading.
Chiron is seriously dedicated about winning the Titan War because if they lose, civilization falls and then heroes may stop rising. So he is no longer needed. May make Greek History lessons a tad more essential.
ZoŽ Nightshade's name becomes this upon reflection:
"Zoe" means "life"—both appropriate given her longevity, and painful given her ironic demise.
The nightshade flower is breathtakingly beautiful—and nightshade is a deadly poison. Beautiful and deadly—coincidence? I think not. Also, the flower is deep purple except for the very center, which is bright yellow. In other words, it has a dark exterior but a heart of gold.
In addition, ZoŽ was once a Hesperid, a nymph of the sunset. Sunset = shadow of night = Nightshade.
Percy. Perseus. Annabeth. Andromeda.
A chance comment by my niece while we were watching the movie of Percy Jackson & the Olympians: The Lightning Thief made this one occur to me, but I doubt it doesn't apply here, too. Hermes' son is Luke. One of the items Luke provides/uses are winged shoes. This basically means Luke is flying because of his feet. The chance comment my niece made: She called him "Luke Skywalker." — Sgamer82
We're told in The Last Olympian that Nico and the Pegasi dislike each other. This mostly seems to be because his father is Hades and children of him are generally outcasts, but in The Sea of Monsters, Percy mentions that Pegasi are sort of neutral territory between Poseidon and Zeus only. So naturally the Pegasi would dislike a son of Hades!
I was always a little confused about how Silena Beauregard got the Ares cabin to believe she was Clarisse and follow her into battle, because she and Clarisse don't look anything like each other. But then in The Lost Hero, it's revealed children of Aphrodite sometimes have the ability to make other people do stuff with their voice. No wonder they believed Silena was Clarisse, she charmspoke them into it!
It's never stated that Silena could charmspeak, but it's a possibility.
I think it's more likely that the entire cabin wanted to go to the fight (because it was the right thing to do) and took any excuse they could get.
The above is pretty much explicitly stated, but it's also a pretty obvious allusion to The Iliad (the need-to-know book for info on the Mist). Achilles (Clarisse) was the best fighter and led the finest men in the Greek army, but (s)he sulked due to having a prize earned in battle awarded to someone else. (Thankfully, Clarisse's prize was a flying chariot, not a slave girl.) At the battle's most desperate point, Patroclus/Silena took Achilles' armor and led his men into battle to hearten the Greeks. Achilles' men knew it's not really their leader, but they want to help the Greeks and will follow anyone at that point.
Something this troper realized after reading the Great Prophecy a few times: Hades got his wish! All three children of the Big Three were the child mentioned in the prophecy! Just hear me out for a moment: Thalia skips out a few days before her age-16-birthday, but she had already been around for at least 16 years before that and did that against all odds (she got turned into a tree after she died). Her choice to 'pass' allowed Percy to be the child. Same for Nico: he too survived against all odds (getting a lightning-bolt thrown at the place you're in is usually deadly) and his choice to allow Percy to 'be' the one gave Percy the chance for HIS choice to give Luke the knife to save Olympus. Ergo: if either Thalia or Nico had chosen differently, Percy would not have gotten his choice and Olympus might have fallen!
Not how prophecies work. The Great Prophecy always referred to Percy, it's just that Thalia could have theoretically been the demigod it spoke of, and Nico (or Bianca, for that matter) could have as well if Percy had been taken out of commission. They didn't know for certain which one it referred to, hence the confusion and manipulation, but it was always going to be Percy.
Also, Nico is younger than Percy. Nico was 10 when introduced, meaning he is about 15 during the Mark of Athena.
After reading through Battle of the Labyrinth, it struck me that one chapter is titled "We Meet the Two-faced God". Well, yeah, of course, it makes sense in this book that it's got such a weird title, so I was expecting them to literally meet a two-faced god. And of course they did — Janus. But who else did they meet in that chapter? Hera. I recall how nice she was to Percy and the others. I also recall a story in which it's said she threw Hephaestus off a cliff... Odd for the goddess of marriage and family...
In the same book, it is pretty much stated that she is almost obsessively devoted to the ideal of a PERFECT family, and, as Hephaestus bitterly remarks, he doesn't quite fit in that with his looks... Not that Zeus' chronic infidelity helps anything.
Rachel, a mortal who had no ties to the gods until she became the oracle, has a very much Jewish name.
This Troper just reread the story of Rachel and Jacob; when she was having problems getting pregnant she used the magic of the Greeks to conceive Joseph and Benjamin.
For quite some time, I was wondering what Blackbeard was doing on Circe's island. After all, he was killed by the Royal Navy. Then I realized: it fits. Blackbeard is the son of Ares. Eurytion is another of Ares' children. Eurytion made a deal with his father to come back to life each time he died, making him functionally immortal. Moreover, contemporary accounts of Blackbeard's death describe his headless corpse swimming around the Queen Anne's Revenge three times. Take all this into account, and it's obvious: Blackbeard made a deal with his father to be effectively immortal.
If the Oracle hadn't made the prophecy that is the driving force behind the series, then Zeus wouldn't have made the law that him and his brothers should have no more children. If Zeus hadn't made that law, then he wouldn't have tried to kill Bianca and Nico. If Zeus hadn't made that attack, then Hades wouldn't have cursed the Oracle which means Luke's mum wouldn't have gone insane which means Luke wouldn't be the person that he was. The fact that the prophecy was made is what made sure that all the pieces were in place ready for Percy 70 years later.
Rachel Elizabeth Dare's initials spell out RED—and incidentally, her red hair is definitely one of her defining characteristics. (Also take into account the fact that her middle name is explicitly mentioned—often—whereas other characters' aren't)
Pollux and Castor. Guess which one of the twins dies while the other one lives.
It's stated in-text that the Gods, Titans and other immortal beings lose and gain power based on how much people remember them. This completely explains why such powerhouses like the Drakon, Typhon, even Freaking Kronos are defeated in just a couple paragraphs. Ask the average person on the street and they'll be able to name Zeus, Poseidon, and Hades. Maybe a few of the others. But maybe one in a thousand could dredge up such obscure details of Greek mythology.
The gods don't have DNA so it's not incest? It is shown as cannon that Percy isn't all that book smart, meaning he probably didn't bother to listen closely enough to learn more than the absolute basics (genes cause traits, are interested from parents) about genetics and genetic theory, and genetic problems come up with incest are not inherent with how closely related they are, but how likely two closely related individuals are to the same recessive genes that cause problems, like the genes that cause hemophilia. Sure, it is possible to have genetic disorders from two unrelated parents, but it is more likely for parents that are closely related to have problems. The thing about the gods are that they are physically perfect, part of what makes them godly is that they don't have any flaws in their genetic code that causes genetic disorders. So, the reasons behind the taboo on relatives marrying when it comes to people related through gods is void, and assuming they aren't related through their mortal parent, two demigods are as likely to have a child with a genetic disorder as two completely unrelated individuals. Marrying siblings from the same cabin is still a little too squick for most demigods, but other cabins are fair game because the repercussions of having children with them is killed by monsters like their parents, not possibly being born without a limb .
Luke's mother is still making sandwiches and kool-aid for a son that will never come home. Ever.
You know how Percy saved Ethan? Ethan, the son of Nemesis, resurrected Kronos because of that.
Before Rachel Eliabeth Dare became the Oracle, the previous one was soul bound permanently to her body. Her corpse was still animated, even after it had been dead for presumably centuries. Therefore the Oracle had been living forever in the mummified body that was once hers. Since the Oracle would have lasted indefinitely until someone gave her a new body (Rachel), what exactly is gonna happen to Rachel's body in a couple hundred years?
That only happened because of the curse Hades placed on the old Oracle. Rachel is not cursed. She'll probably retire at the standard retirement age of 65.
In book two, Percy talks about seeing a father and his two elementary school-aged daughters on the Princess Andromeda, along with other guests. In book four, all the guests are gone. Percy theorizes that they "didn't get to leave with their bingo winnings". This includes, of course, the father & his daughters.
Take it one step further and consider the ship's inhabitants: ( Kronos' army of monsters). They were most likely fed to aforementioned monsters. Full stop.
In Son of Magic (Short story by Riordan's son, found in Demigod Diaries), Alabaster, son of Hecate, states that when Beckendorf and Percy blew up the Andromeda, not only were monsters lost, but demigods who had sided with Kronos.
The Labyrinth was destroyed. Now, imagine how many people may have been inside when it collapsed...
Considering the slim chance of them actually getting out and not dying painfully of starvation, dyhration, and exhaustion, it was probably a Mercy Kill.
Nico spends a lot of time just roaming around, especially right after he runs away from camp when he was ten. Just think about that for a moment. A ten year old living on the streets of Manhattan alone for who knows how long.
At the end of The Lightning Thief, Percy's mom turns her husband to stone, with Percy's help. For the entire rest of the series, no one brings it up again, or comments on the fact that this is murder.
Well, with a just afterlife murder is going to be far less of a crime than it is in our world.
Bear in mind that this is a Greek epic written in modern times. People got away with that stuff all the time in those myths, especially to people as foul as Gabe.
Imagine that you are one of the rare mortals who can see through the Mist, like Sally Jackson or Rachel Elizabeth Dare. You grow up, seeing monsters attacking the city and strange kids with powers your entire life. Because few others have your ability, nobody believes anything you say about what you've seen, and you start to wonder yourself if you're actually insane. Your only hope for mental safety is for your ability to help run you into a half-blood who might be able to explain things to you - and doing that means you've become involved in their dangerous lives...
The Underworld/Afterlife. First, if you cannot pay Charon. Too bad, you're stuck until he feels nice. (100 years according to the most common version.) Second, the judges of the underworld can show bias as evidenced by Minos meaning they might not always be fair. Third, where you go heavily depends on what the gods think of you. If you have their favor, it might save you from the Fields of Punishment or even get you in Elysium. If you have angered a god unknowingly or hated the Olympians for them making your life miserable you can easily be denied Elysium or end up in the Fields of Punishment. Fourth, if a new group of deities takes over the laws that decide where people go can change and even those in Elysium might find themselves in the Fields of Punishment for supporting the old order. No wonder most people choose the Asphodel Fields. Just imagine standing in a wheat field in the middle of Kansas, forever.
The lives of the monsters. For the high crime of existing they're forced to fight a war in which their own kin kill them callously, over and over and over again . . .
Not really if you think about it. Satyrs and Cyclops are monsters but don't have to fight over and over. Plus Percy and Co. were alright with having a hellhound. The only reason that monsters die is because they WANT to harm/eat/kill demigods. The average demigod is willing to leave monsters alone. Its the monsters who CHOOSE to fight and subsequently die "over and over again".
