There has been alot of talk about Joseph Smith being wrong about the facsimiles being not what he thought, that they are just typical burial writings found in many coffins. What is proposed tough is that the Egyptians got the original drawings and teachings from Abraham in the first place.
Here is facimile #2:

There is a mountain of things that could be said about what is contained and taught in that picture. What is to be understood is that this is an effort to display the prophetic vision similar to that discused by Lehi in Nephi chp 1 and by Moses in Moses chp. 1. The doctrines taught in Abraham concernign the pre-existence no doubt came from this vision.
In the various Abraham accounts, both ours and others known (And the things taught in these other book of Abrahams support Joseph Smiths account), Abraham is shown all these things by an Angel.
At the outset of their journey, the angel promises to show Abraham what is " in the fulness of the whole world and its circle - thou shalt gaze in (them) all." Accordingly, he saw the pattern of the heavens, "the firmaments,... the creation foreshadowed in this expance,...the age prepared according to it. And I saw beneath the sixth heaven,...the earth and its fruits, and what moved upon it... and the power of its men... And I saw there a great multitude - mean and women and children, [half of them on the right side of the picture] and half of them on the left side of the picture." "And I said... 'Who are the people in this picture on this side and that?' And he said to me: 'These which are on the left side are...some for judgement and restoration, and others for vengeance and destrruction... But these which are on the right side of the picture,... these are they whom I have ordained to be born of thee and to be called My People'" "And I looked and saw; lo! the picture swayed and [from it] emerged, on its left side, a heathen people, and they pillaged those who were on the right side." (Apocalypse of Abraham)
Note that Abraham was shown all these things in a picture, a graphic representaion of "the whole world in its circle," in which the whole human race, "God's people and the others," confront each other beneath or withen the circle of the starry heavens, on opposite halves of the picture. To the classical scholar, this evokes one of the most ancient and venerable images of antiquity, the famous Shield of Achilles, as described by Homer in book 18 of the Illiad

it was a great round (Grosskreutz.antyx) shield, with a conspicuous rim around the outside, representing the celestial ocean. it was covered with designs of deep signifigance (Grosskreutz. iduiesi prapidessin), designating earth, sea, and sky, including sun, moon, and constelations, in their relative positions and motions. Human society was also indicated, divided into two parts, one, a community at peace, the other at war. The former are engaged in religious rites and festivals, marriages, dancing, and music and games, with housewives relaxed and happy watching from their doors; there is a solemn but lively law court in session in the town square, with freedom of speech and great prize for the wisest. A long idylic poem describes the happy agrarian life, enjoying the fruits of the earth in its seasons in a peaceful and prosperous kingdom. The other city is at war, besieged on two sides by armies that are already quarreling over the expected loot, even while the besieged are laying deadly ambush for them. What a fine sight as they go forth in their splendid armor! But presently the fine sight becomes a nightmare, an orgy of slaughter on both sides, as Eris (Strife, contention) and Confusion enter the fray while Fate in a blood-soaked robe runs about spreading havoc and butchery.
The pictures are equally lurid and inspiring in Homer's and in Abraham's accounts. While Abraham is repeatedly invited to inspect and ask about "the world and its circle," Homer refers us to an equally tangible design placed on a round shield. Those whp protest that it is extravagent if not impious to look for ties between the Father of the Faithful and the pagan Homer may be referred to the earliest and most revered of ancient Christian apologists, Justin Martyr himself, who sees in the Shield of Achilles a most obvious borrowing from the book of Genesis, explaining the coincidence by suggesting that Homer became aquainted with Moses' cosmic teachings while he was in Egypt. For him the shield "proves that the poet [Homer] incorporated into his own work many things from the sacred history of the Prophets; first of all the account of the Creation in the Beginning as given by Moses, 'In the beginning God created the heaven,' etc. Having learned these things in [i]Egypt, and impressed [pleased] by what he [Moses] had writen about the origin of the cosmos, he depicted it in the Shield of Achilles, with Hephaestus [the Smith] in the role of the Creator of the world."
