“Supper at Emmaus” by Michelangelo Merisi da Caravaggio
In the 1601 painting “Supper at Emmaus” by Caravaggio, it depicts the scene in the Bible where Jesus comes back from the dead, and reveals himself to his disciples Luke and Cleopas at an Inn. There is a shadow cast in the basket of fruit. But if you look closely at the wicker, there is the Ichthys emblem, which looks like a fish. (In modern times, a lot of people refer to the Ichthys emblem as the “Jesus Fish”, which is famously put all over t-shirts and bumper stickers.) This is popularly believed to be a reference to when Jesus magically fed a huge crowd of people with just a few fish.
