Ariel’s grotto is a treasure trove of human artifacts. We can assume that most were found among ship wrecks that Ariel investigated, which leads to a variety of items.
Abraham Lincoln: This one is pretty random, blink and you will miss it! During Ariel’s song, “Part of Your World”, a bust of the 16th President can be seen sitting on a shelf.
Mary Magdalene: Here we see a replica of Georges de La Tour “Magdalene with the Smoking Flame”. As Ariel literally wonders how fire works, she stares longingly at the flame in the painting. Just as Mary, Ariel is seen as an outcast wanting to be a part of something bigger.
