Idk completely why, no matter how many times I read the books, I always feel that the notes in Snape's book were actually written by Lily, and not Severus. I have some minor supporting theories but other than that no real reason to think this way. For starters, a lot of the tips do look like they are written to someone and not just notes for the self. The larger reason is that the handwriting is mentioned several times to be effeminate. The handwriting is described in a way to make me think it's very distinctive and should be identifiable. It wouldn't be unreasonable at all to expect the golden trio to recognize Snape's handwriting, given they've now had 5 years of the man marking their essays, leaving notes on homework, and writing on the board. Even at approximately 15 years from the time of writing, Snape's handwriting wouldn't have changed so much that it's indistinguishable. Especially for Hermione who just kinda Does That. But as no one has any idea of Lily's handwriting at the time, that makes more sense to me that they wouldn't recognize it at all. It also makes more sense to me for why Snape would keep the book after all these years. If it was full of Lily's notes and advice, he'd be more likely to want to hold onto it, whereas I can't really see someone holding onto their old textbook for fifteen years, unless it's something lost in like an attic, but in this instance Snape would have had to have held onto it deliberately for it to end up out of his home and into his office six years later.(I believe he started working at hogwarts at 21, right?) He would have had to deliberately pack it into his belongings, and why would someone carry along an old textbook? Oh! And Slughorn calls Lily a potions prodigy, doesn't he? He commends snape for his skill but Lily was the natural at potions. If snape was the one correcting the book, it would stand to reason that he would be the prodigy!(I may be mixed up at this point, I haven't read HPB in years) Regardless, it just makes more sense to me for the notes to have been written to Severus from Lily, even if sectumsempra was created by Snape.
I believe this one is also from you Nonny:
Oh this is the HBP anon I just wanna make clear that I feel Snape's feelings towards Lily are 100% platonic, but didn't initially feel that was relevant to what I was saying.
Sorry for being so late in answering you - not been around much these last few days. I hope you will forgive me :)
There are a lot of theories about Snape’s Potions book (the dumbest being that this was James’ book *facepalm*), I personally I’m 100% convinced that those are indeed Snape’s notes. To address your clues about them being from Lily, here are my thoughts:
- have you ever written a journal? We do tend to write to someone in them, it’s the same here since it seems that the notes are way more than just potions tips and corrections going by Harry’s attachment to the Prince;
- handwriting has no gender, it’s a silly notion (this is coming from someone who was a little girl with a horribly messy handwriting). Also, I don’t know about you but if you compare my highschool notes to anything I handwrite today you wouldn’t be able to recognize it either. In particular if you were to compare notes cramped in the margin of a book and intended only for myself to something where I would put up way more effort like writing on a board for other people;
- About him keeping the book for that long, it does make sense since it’s full of experimental notes. I still have some chemistry notes from my Uni days that I kept even after my PhD because it was useful. It’s the same for Snape here I think, especially since we never hear about any post highschool education in the wizarding world. There is also the possibility, since it was found among other old potions books, that Hogwarts keep old books to lend to students in need and Snapes’s happened to be among these old books;
- Now, about Slughorn, you need to take some things into account. First, when we see him talking about Lily’s potions skills, it’s always to Harry. It makes sense that for an orphan hearing about his mother is way more relevant in that context than his hated potion professor, even if the latter was equally good or even better. Add to this that Lily was pretty and popular while Snape was dirty poor and an oddball and it’s not difficult to imagine old Sluggy preferring Lily to Severus even if their skills were equals. Since I already did some dig up in the books about that specific topic, allow me to quote myself here:
I dug up my old copy of HBP in order to see exactly what Slughorn had to say about Snape’s abilities at Potions and it is cementing my first take that Severus was indeed the exceptional student while Lily was “just” very good.
This is from the chapter “The Unbreakable Vow” in HBP, the scene during the Slug Club where Slughorn is praising Harry’s skills to Trelawney just before Snape appears:
‘But I don’t think I’ve ever known such a natural at Potions!’ said Slughorn, regarding Harry with a fond, if bloodshot, eye. ‘Instinctive, you know — like his mother! I’ve only ever taught a few with this kind of ability, I can tell you that , Sybill — why, even Severus –’
That last bit clearly illustrate for me that for Slughorn, there were a handful of very good instinctive students – Like Lily –, and then Severus Snape above them.
And a little bit further, while raving about Harry’s Draught of the Living Death to Snape himself:
‘You should have seen what he gave me, first lesson, the Draught of the Living Death – never had a student produce finer on a first attempt, I don’t think even you, Severus –’
Again, it sounds as if Severus Snape was, until Harry, the unchallenged best student Slughorn ever had.
So you see, for me, it’s Snape’s book, it’s Snape’s nickname (I would pay to see his adult self cringe hard at his ridiculous teenage nickname tbh) and it’s definitely Snape’s notes.
It’s also very important that those are indeed from Severus Snape from a narrative point of view. The connection Harry felt, his deep empathy for the Prince coupled with how good he suddenly was in Potions under his tutelage is so important:
- it shows how similar Harry and Snape are despite their unfortunate hatred, a parallel (along with Voldemort), that is pointed out several times in the books (the lost boys who call Hogwarts “home”);
- it shows that Harry, while looking like James, is indeed more like Lily in nature and felt instantly deeply connected with young Severus, they could have been best friends;
- Harry’s relationship with the Prince indeed parallels Lily’s relationship with Severus: a deep connection of true kinship, a fascination deep fried in a thirst for knowledge, a visceral feeling of closeness, and then: betrayal.
- it shows that, despite the mean professor persona, Snape could have been an excellent teacher to Harry, if only he could have let go of his bitterness;
- it’s important because it’s a rare window into the true Severus Snape, not an act he’s putting up for the world to see. It was the first clue about his true nature and it’s very interesting that it was given to us just before Snape killed Dumbledore, apparently casting him as evil in the eyes of Harry and by extension the reader.
Here it is friend, I hope I could convince you and if not, it’s ok, it was a fun discussion. Thank you for the ask.
