Starting in the upper left corner...
1. First ol' Jackal-Head, the god Anubis, leads you in front of 14 judges. They decide whether or not you get into the afterlife right away. I've heard two different versions - those judges are either the gods of major Egyptian cities, or just some bunch of Lesser Gods. I've also seen 12 instead of 14 judges on different papyri.
Anyhow, each judge holds an
ankh. If the judge raises the
ankh, it means - "thumbs up, welcome to the afterlife." If the judge does not, tough luck, no afterlife, welcome (back) to oblivion. But since there are always an even number of judges, tie votes would be common.
2. With the judges deadlocked, Anubis takes you down to meet Ma’at, the winged goddess of truth and justice - she's the tiny, hard-to-see figure on top of the scales. Ma'at plucks a feather from her wing and Anubis weighs it against your heart, in the scales.
If your heart weighs more than the feather, your heart is heavy with evil. The little blue guy beside Anubis, with the head of a crocodile and rear body of a rhinoceros, is Ammut. He eats your heart, then the rest of you. Go directly to oblivion, do not pass Go, do not collect an Afterlife.
3. If the feather outweighs your light and sinless heart - congrats, you're in! The Egyptian god of journalism and bean-counters, ibis-headed Thoth, writes down the verdict of your trial. Pretty much like St. Peter etc.
4. Then Horus, the guy with the falcon head, escorts you in to meet the V.I.P.'s of the afterlife: Osiris, holding a shepherd's crook to symbolize that he is the shepherd of all humanity (which also sounds vaguely familiar). And the flail, used to separate wheat from chaff - symbolism obvious. The lovely ladies are his wife Isis and his sister-in-law Nephthys. Party time!
Bonus Irrelevant Trivia: when a modern Egyptian mom is feeding a baby, she will hold the food up to its mouth and say: "Mut-mut-mut!" or "eat it up." That's a direct reference to Ammut. I never saw an Egyptian mom feed her baby a heart, though. And as an atheist in Egypt, I nearly starved due to a severe lack of Xian babies.
