The mystery of the coded notes found this winter inside books at Western University's D.B. Weldon Library appears to be solved.

The notes, coded with symbols, were accompanied with either a leaf, feather or jewel attached.

The notes garnered international attention

"It got so much attention around the world that I was getting 100-150 emails a day of people asking questions about the note," says Western professor Mike Moffatt, who found the first note.

Moffatt became enamored with the mystery. He blogged about it and then more started to surface.

It even became a bit of a treasure hunt and soon after, a pattern was discovered

"All the notes were hidden in books that were five feet off the ground so close to eye level for people. And also they were placed between 16 and 17 of the books they were hidden in," Moffatt adds.

Interest grew and all kinds of different groups, from linguists to mathematicians.

"We discovered that all the symbols do accord to a letter so the diamond may mean the letter 'D', something like that. But once you translate the notes they are just gibberish they don't actually say anything," says Moffatt.

An art professor at Western confirmed the notes were part of an arts project that was done two years ago.

The student who came up with the idea wants to remain anonymous.

"I am a little disappointed that there was no treasure at the end of the rainbow. But it has been a fun adventure," says Moffatt.
