Final answer:
The claim that Scylla and Charybdis are two sea monsters located on either side of a narrow strait in the Mediterranean Sea is true, and they are iconic figures in Greek mythology.
Step-by-step explanation:
The statement about Scylla and Charybdis being two sea monsters located on either side of a narrow strait in the Mediterranean Sea is true. These mythical figures are well-known elements of Greek mythology and are particularly recognized for their role in Homer's Odyssey. Scylla and Charybdis posed a dire threat to sailors who had to navigate the narrow passage between them, embodying the perilous decision between two evils, often referenced in the phrase 'between Scylla and Charybdis.'
The source of the allusion in this context refers to these myths which are embedded in the cultural legacy and often appear in literature and art to symbolize difficult dilemmas. The rich tapestry of Greek mythology, including the stories involving Perseus and Andromeda, the work of blind poet Homer, and various mythological figures like Circe and Chiron, are testament to the enduring influence of these ancient legends in various aspects of culture.
