What is an example of allusion on the novel, Waiting for the End of the World?

Bell uses myths to signal the direction of Larkin's life. On the personal level Larkin has created his own family myth, using facts from the life of Arkady's grandfather. He tells people that his Ukrainian grandfather used a cross to kill a thief in a church and, after ten years in prison for the offense, voluntarily exiled himself to America.

Instead, Larkin's father originally supported the Russian Revolution, and, in Larkin's childhood, Lenin's picture was prominently displayed on the wall.

Also on the personal level, Arkady links Larkin with the myth of the unicorn, warning him that the proud unicorn — who preferred solitude to Noah's ark — swam for twenty days, until a little bird landed on his horn and the extra weight pushed his head beneath the water. The most important myth associated with Larkin, though, is Tsarevitch Ivan's quest for the Firebird.
