The lever on a lighting control console that simultaneously dims all the channels from one cut to the next is a crossfader.
A crossfader can be defined as a control on a DJ mixer that allows the mixes to be created, so nowadays is a very basic tool.
The crossfaders became common in the '70s when they were used by the DJ to make mixes.
The correct answer to what does Brueghel's painting include that isn't mentioned in Ovid's original myth about Icarus is C. A ship.
In Ovid's original myth, Icarus and his father Daedalus escape from the island of Crete flying with wings made by Daedalus using feathers and bee wax. While they succeed in flying, Icarus ignores his father's warning and flies too close to the sun. The wax melts and he falls to the sea and drowns.
Ovid mentions obviously the sun and Daedalus, since they are crucial elements of the myth, but he also mentions a ploughman and a shepperd who are "astonished and thinks to see gods approaching them through the aether."
The only element that is not mentioned in the myth and appears in the painting is the ship, which may have been included to give more power to the composition of the painting.
