The Prometheus Mural, Necronomicon and Covenant

Dude, you need to read the novel but I'll share what I have read here. Shaw dies from the goo sperm infection and David is mad at himself plus the engineers. The engineers of lv223 MISUSED the catalyzer seeding goo given by the elders I.e. those old dudes in Prometheus deleted scenes. It had a built in fail safe "punishment" which is the horrific pathogen to which the dumbasses on anthrax island 223 spilled something just like Weylen built a psychotic uncontrollable robot. Ridley has served us a diarrhea smoothie and well quite frankly it tastes like shit. Yeah, it's a mess and the books under ten bucks. If I were not so dang triggered by Covenant's Android Comedy Show I'd buy it and read it. So much potential and of course the easy out here is to blame "dumb xenomorphs fans" for making ridley do what he did. That's a zombie afterbirth sundae that has no merit as the buck stops with Ridley and he chose this path and the box office has spoken! The masses don't like it but !maybe someone fixes it someday, who knows

Still a lot left open to interpretation... i am not sure the Novel Spoons feeds this information as far as the History of the Engineers and Black Goo... i have ordered it though

But Capt Torgo indeed from what we know about Prometheus and comments made by RS, i think your interpretation and what the OP was trying to get to, could be partially correct.

@NATHAN

This depends really down to if the Mural is just a Easter Egg and nothing more... RS had said it was.. or someone else with Production... but i think it had a purpose to Show that the Black Goo and Xenomorph are CONNECTED.

I wont cover the Fresco now as they was not shown much, especially the Egg... this was on screen for a split second and not fully... but the other Fresco looks like Prometheus Punishment to me... but i will cover that latter.

The Mural in Prometheus if i take it as being Canon and not just a Lazy Easter Egg... Shows us..

*TWO Different Face Huggers (Alternative HR Giger Early Designs).

*DEACON Type Xenomorph In Cruciform Pose.

It is likely the Engineers came across a Organism, or Created one or was Punished by One... that lead to Engineers being infected and Chest Busted... these Engineers then in-turn was never all killed by this events... but they saw this event as some kind of Freedom from Bondage... they maybe worshiped how this events had lead to Engineers being able to Birth New Life...

So the Engineers Experimented and Created different Face Huggers and Sacrificed themselves or other Humanoids Until they had Achieved the Deacon-like Organism in the Mural.

At this point they likely Sacrificed this Organism via the Sacrificial Goo and Collected the Broken Down Mutagen and had it Weaponized into the Urns... so these Engineers then saw this Deacons DNA as Perfection they then sort to use this to Evolve Worlds rather than their Engineer DNA... maybe these beings wanted to use it to Destroy their Creators Favored Creation Mankind?

The whole how Mankind fits with the Engineers is a very open subject....

The whole Watchers, Dark Angels aspect was to be explored, the whole Mythos of the Engineers connected to Ancient Mythos and Religions was to be explored.

But alas Prometheus:Pandemonium did not happen.. and we got Alien Covenant...

There was TWO Main Mythos they was following... Greek and Biblical Accounts...   Greek Mythos we have a Multi-layered Hierarchy of Gods, and the accounts of the Order of these Gods being concerned about Rebellion of their creations, because they in turn rebelled against their Creator/Father on more than One Level.  A Betrayal of Prometheus against his fellow Titans helped the Titans Children the Olympians overthrow the Titans.... Prometheus then performs a Betrayal on these Olympian Gods by Evolving/Corrupting Mankind with Forbidden Knowledge. Prometheus is Punished for this.

Biblical Theme also follows this loosely, we have a GOD, whos favored Creation became Rebellious (some) and these were Expelled from the Kingdom of GOD and Punished.  And GOD then Creates a New favored Creation Man, who the Angels are to watch over and to respect as Gods Perfection... But the Banished and Punished Satan sets out to Corrupt Gods new Creation by tricking them to gaining Forbidden Knowledge... which then Satan is further Punished for.

We can see a connection between Prometheus/Lucifer, we can also see down the ladder that David now fits into this same Mold.

If we look at the Annunaki Tale, it also fits.. in which a Race of Gods had created a lower caste Igigi to perform certain tasks so that the Gods do not have to... these Igigi Rebelled against this and so Mankind was created to replace them... The Igigi would thus fit in with the Angels or at least Fallen Angels. This tale is more deeper and if we get into it deep then Enki kind of Parallels Lucifer/Prometheus.

How does this all connect? 

Maybe the Engineers are a lower caste, who was created to perform a certain task (Sacrifice) for the Hierarchy and some of these Rebelled against this... and then was cast out of Paradise, Maybe Mankind was created to then replace them for this Sacrificial Role?  Or Mankind had already been Created and they was the Reason for the Sacrifice... so that Humanoids could be created... for what reason? who knows..

Maybe the Elders/Engineers lost Females at one point?

So after Rebellion maybe the Engineers had a War with their brothers and Creators... maybe they then decided to take domination of Mankind and act as Gods... but we rebelled?

Maybe they created Mankind as a attempt to be Gods themselves?

There is so many ways this can all come together..

It is rumored the Shaw/Li connection was to be more Bio-Mechanical, but this was changed... and what we have is Dr Shaw being a Experiment for David.... she played a KEY Role to how David obtained those Eggs...

The Novel seems to suggest a bit otherwise.. but i think the Changes to the Plot that now has David as creator of the Eggs is going to be Canon.

Who knows what happened to Shaw... some say she died due to the infection from Prometheus...however Shaw's Hair in the Crossing Prologue has grown so long that depending person to person would be 6-12 Months Hair Growth.... its Likely Shaw was reluctant to Rebuild David and it took Months and Months before he gained her Trust....

Shaw thus could not have been badly affected from the event with Holloway, its likely she looked ill because of a Lack of a Good Nutritional Diet.

It would appear that David saw Shaw's kindness towards him as the way he had longed to be accepted by Mankind.  

"The greatest thing you'll ever learn
Is just to love and be loved in return"

Nature Boy Lyrics (AC Trailer Track)

so its likely David grew very Fond of Dr Shaw, so much that he fell in love with her... in more than a Platonic Fashion and i will assume David had even tried to make Advances, which caused Shaw to Reject him, and feel Creeped out... David did not take this Rejection well and ended up killing her, he felt hurt and that indeed the greatest thing he will ever learn is not to Love and be Loved in Return, his rejection by Shaw in his eyes made him think All Humans are not worthy and never appreciate him.

He then regretted what happened.... it destroyed him, Shaw wanted her answers, he knew this would be  a waste of time that would most likely lead to Her Death and his Destruction.. so he had to kill the Engineers off, he found out what they are like anyway.  So he denied Shaw her Answers.. this is the only Thing Shaw had Left... She had nothing else.

*Mother and Father Dead.

*Her Fiancee Holloway Dead.

*She has no Children and Cant.

All she had left was to know WHY these Engineers Created us and WHY they wanted to destroy us, surely they Nurtured us for Thousands of Years... WHAT HAPPENED and so WHY did they Changed their minds...  She would have been prepared for the risk of going to where THEY came from, and even if it meant She would DIE i think as long as she FIRST got her ANSWERS then she would be fine.

But David could not allow this... He Loved Shaw, she was the only Human to make him feel equal, and important at least in his Eyes.... he could not allow his Companion Dr Shaw to DIE

But in Protecting her by Killing the Engineers, he had TAKEN Away the One thing Shaw had Left.... Her ANSWERS She wanted.

David would have been very fond of Shaw in more than a Platonic way... Fassbender said they was like a Married Couple.. at least in his eyes.

He may have saw them as a Couple and not Friends... and from everything he gained from Peter Weyland what makes a person Important is their Legacy... and Creation is just that, it leaves behind your Legacy and in part is what Weyland thought made him a GOD.

The whole Tale from Prometheus has been about Creator Creates, then Creation Rebels and Sub-Creates and the Sub-Creation Rebels and Sub-Creates.  This started with the Elders it ended with the creation of David

David can-not create or bare Children and neither can Dr Shaw, but if David could CREATE then he would have a Legacy.

So after killing Dr Shaw... David regrets and feels great despair... but he sees that he can use Dr Shaw to Create his own Creation... from Dr Shaws Body he can Create Perfection and so Shaw's Life would not be in Vain.... through her Death he could give rise to her CHILDREN and his Creation...

Davids Creation is thus his Child and Dr Shaws Child.

This is why David referred to Dr Shaw as his Greatest Achievement.
