I will answer the mystery behind Ultimecia’s paintings
First you have to know that Ultimecia is the one who painting it.
So Ultimecia is a painter (I don’t want to argue about this painter thing).
I hope someone will show that painting in this thread because I can’t find it.

Intervigilium/Sleep represents “Eternal”.As long as you are sleep you are still alive.Ultimecia is Eternal (you can read the expalanation in My thread "Rev of the Truth").

Ignus/Fire represents two things; First “Passion”.Ultimecia has strong passion to achieve Time Compression.
Second “Anger”.Ultimecia angry to human and everything she hates.These two things are right no matter how you look at it.

Inandantia/Flood represents “Powerful Force”.Ultimecia has powerful magic.

Iudicium/Judgment represents “Misery”. Once Ultimecia achieved Time Compression she will create a Dimension for human to make human's life misery.

Vigil/Watchman represents “Sorceress Knight”.I dont want to explain anything about this one.

Viator/Messenger represents “Message/Secret” .Ultimecia wants to find/will to find this Message/Secret.

Venus/Love represents “Love” This is the fact that Ultimecia ever loves Someone.

Xiphias/Swordfish represents “Freedom”.Swordfish is one of the fastest of all fish.It’s scaleless, muscular body is designed for high-speed swimming. This fish can swim at speeds up to 60 miles (97 kilometers) per hour.Swordfish is free in ocean and hard to catch because of their high-speed swimming. So Ultimecia wants freedom,she can has the freedom to do anything once She achieved Time Compression.

Xerampelinae/Red Clothes represents "Mystery".Ultimecia painted a Women with red clothes and it's WEIRD Ultimecia only name it (the painting) with Xerampelinae/Red Clothes.What the Women purpose then? It is still a mystery.
So it represents the mystery of Herself.

Xystus/Tree-lined road represents "The Never Ending Journey".Ultimecia painted Someone in that painting.And this Person run through the Tree-lined road.You dont need to know who this Person is,I wont tell you.

Inaudax/Cowardice represents “Cowardice” Ultimecia sees human as a coward this “Cowardice” represents human's life in
Ultimecia’s perspective.

Vividarium/Garden represents “Happiness” Ultimecia wants happiness, the only happiness She wants is when she achieved Time Compression.

The meaning of Vividarium et Intervigilium et Viator is In the Garden Sleeps a Messenger.
Ultimecia is the one who make that painting.Ultimecia painted a Man sleeps in the garden.And this man is a messenger.
Garden represents Viator’s life in the perspective of Ultimecia.
If you look at the face of that Man you will actually see Squall’s face.
YES The Man in that painting IS Squall in the eyes of Ultimecia.That Man represents Squall.
Viator IS Squall Leonhart.
Viator sleeps and he will wake up someday to deliver message.
Squall Leonhart ; Sleeping Lionheart.
This Lion/Squall will wake up someday.
It’s a bad situation if you know the Lion is awake. This Lion/Squall will KILL You/Ultimecia if He/Squall wakes up.
Remember Odin said “The Heaven hath decreed Thy Fate PERISH BY MY SWORD!”(btw this is not the case I just take the example)
if you fail to fight Odin after time is over.
It’s the same thing,"Squall will decree Ultimecia’s Fate PERISH BY HIS SWORD!"
So Squall is Messenger of Fate for Ultimecia.
That Message/Secret is Ultimecia’s Fate.
