Iago’s age is not explicitly stated in Shakespeare’s play, Othello. However, it can be inferred from various contexts within the play. Iago is often depicted as a soldier and is described as having experience in warfare. Given that he has a position in the Venetian army and has a wife, Emilia, we can deduce that he is likely in his late twenties to early thirties.
Furthermore, Iago refers to other characters, such as Othello and Cassio, in ways that imply a level of maturity and experience, suggesting he is older than Cassio but younger than Othello. This places him in a range where he possesses enough life experience to manipulate those around him effectively.
