# An Elementary Magnum Opus

The image below is modified from a part of an absurdly high-resolution "magnum opus" picture. Based on the magnum opus's contents, answer the following questions:

• What is the meaning of the black line near the bottom-left corner of the image below?
• What do the box colours signify?
• Within the magnum opus there is one fictional character directly under the motif that was modified to make the image below. That character's name can in turn be entered into one of the boxes below. What is that character and which box does it go into?

Much like one of my previous puzzles, the image here hides a link to the magnum opus. The puzzle was also intended for Stiv... in a way.

Individual images are available on the same site for your convenience in answering the questions. Check the tags too!

• @Prem comments are not for "wild guesses"; if you have an answer then put it in an answer with reasoning to back it up. Banter and back-and-forth help are not the purpose of comments. Sep 25, 2021 at 17:15
• Re the hint: One of the first things I did was count the number of boxes...! Right now I'm still mulling over possible colour connections...

• @bobble , over the years, I have used comments for various purposes except spam; Nobody has ever objected till now; I do not agree with your sentiment. Maybe, you did not see the replies to my comments (Parcly has deleted those comments) and it currently looks like I have made 3 odd comments. No matter; With Parcly deleting the replies, I too have to delete mine, which I will do in a couple of Days....

Partial Solve, original solution had errors, I have proposed answers for two of the three questions, but no idea on the third.

The number of boxes and length of lines align with the Table of Elements. There is also a clue in the title (Elementary).

This gives us the following mapping:

If we map the numbers to the squares they lie on, we get the string:

D Er P I B O O Ru (taking the first 2-1 to be D for 'Deuterium - credit Stiv')
Which meant nothing to me until the hint pointed me to a previous post explaining that "Derpibooru" is an image hosting site aligned with My Little Pony.

The "A B C D" maps to the following:

A=Fe=26 B=Np=93 (credit stiv for pointing out an error in original post) C=Fr=87 D=He=2

Giving us the index of the image at Derpibooru, 2693872, which gives us a relevant picture at https://derpibooru.org/images/2693872

On to the questions:

What is the meaning of the black line near the bottom-left corner of the image below?

No idea, I am out of my league with mlp fandom

What do the box colours signify?

I believe they align with the official mlp vector fill color associated with the figure in that box. For boxes with two figures, two colors are shown. I cross checked ten and they seemed to match, but I could be wrong.

Within the magnum opus there is one fictional character directly under the motif that was modified to make the image below. That character's name can in turn be entered into one of the boxes below. What is that character and which box does it go into?

Perhaps my original answer is still valid? This could be wrong, but one of the two top ponies is a modified version of "Pinkie Pie", drawn holding a balloon. That character is also known as "Ponka Po" in some markets, so I would propose that their name "Po" should go in the violet box labeled "Po" (for Polonium) in the above picture showing the mapping to the elements.

• For the '2-1' translation, I suggest you use this :)

• Also, what you have labelled 'Pm' should be 'Np' (you've read off the wrong row of the table). This all leads you to this much more thematic picture.

• I looked at this over and over and couldn't find the error but you're right. @stiv if you can solve the puzzle, go for it, otherwise I'll look at this when I have time.
