Final answer:
Brabantio accuses Othello of using witchcraft and charms to make Desdemona fall in love with him.
Step-by-step explanation:
In Shakespeare's play Othello, Brabantio claims that Othello used witchcraft and charms to win his daughter Desdemona's love.
According to Brabantio, Othello could not have attracted Desdemona by normal means, given the differences in their ages, races, and cultural backgrounds.
In Act I, Scene III of Shakespeare's play Othello, Brabantio accuses Othello of using spells and potions to manipulate Desdemona's feelings.
He believes that Othello couldn't have won Desdemona's love on his own and that he used supernatural means to make her love him.
Brabantio's accusations reflect his disbelief and racial prejudices as well as his shock at his daughter's unexpected romantic relationship with Othello, a Moorish general in the Venetian army.
