Othello, also called The Tragedy of Othello, the Moor of Venice, is a play written by William Shakespeare around 1603 set in both Venice and Cyprus about a General subjected to the manipulations of his jealous subordinate.
Alesand would eventually record how, in 971, she and the other locals (human and gargoyle alike) of Wyvern Hill twice saw an "Italian play" performed by an acting troupe known as the Light-Bringers. Unbeknownst to (at least) her, this play featured characters and plot elements bearing some resemblance to Shakespeare's future play. ("The Draw", "The Dream")
Real World Background
In addition to Shakepeare's primary source of Cinthio's Hecatommithi from 1565, there are several inspirations for the play, including the War of Cyprus in 1570, and the Moroccan Ambassador Abd el-Ouahed ben Messaoud ben Mohammed Anoun's visit to Queen Elizabeth's court in 1600. It was likely first performed for James VI/I.
Unlike Gargoyles characters that are direct adaptations from other Shakespeare plays (most notably from Macbeth and A Midsummer Night's Dream), Othello's characters have been reinterpreted in the character analogues of Coldstone, Coldfire, and Coldsteel. When Marty Isenberg and Robert N. Skir wrote the first draft outline of "Legion", the Coldtrio's backstory reminded Greg Weisman of the dynamic between Shakespeare's Othello, Desdemona, and Iago, and he later suggested the names be used as designations to better keep track of their pre-massacre personas inside Coldstone's mind.  The backstory's sequence featured Goliath fulfilling the role of Cassio.  The Othello-themed designations were also used in "High Noon".
During the show's development, early names for Goliath included Othello as a possibility.
