And here is that passage in The Merchant of Venice, in Act 1, Scene 2, when Nerissa asks Portia for Portia's opinion about three of the suitor who have come to Meryto---I mean, Belmont---to seek Portia's hand in marriage:
NERISSA But what warmth is there in your affection towards any of these princely suitors that are already come?PORTIA I pray thee, over-name them; and as thou namest them, I will describe them; and, according to my description, level at my affection.
NERISSA First, there is the Neapolitan prince.
PORTIA Ay, that's a colt indeed, for he doth nothing but talk of his horse; and he makes it a great appropriation to his own good parts, that he can shoe him himself. I am much afeard my lady his mother played false with a smith.
NERISSA Then there is the County Palatine.
PORTIA He doth nothing but frown, as who should say 'If you will not have me, choose:' he hears merry tales and smiles not: I fear he will prove the weeping philosopher when he grows old, being so full of unmannerly sadness in his youth. I had rather be married to a death's-head with a bone in his mouth than to either of these. God defend me from these two!
NERISSA How say you by the French lord, Monsieur Le Bon?
PORTIA God made him, and therefore let him pass for a man. In truth, I know it is a sin to be a mocker: but, he! why, he hath a horse better than the Neapolitan's, a better bad habit of frowning than the Count Palatine; he is every man in no man; if a throstle sing, he falls straight a capering: he will fence with his own shadow: if I should marry him, I should marry twenty husbands. If he would despise me I would forgive him, for if he love me to madness, I shall never requite him.
So, now, Part Two of my quiz, which is much easier than Part One---which THREE Austen characters are based, in part, on the Neapolitan prince, the County Palatine, and Monsieur Le Bon, respectively?
If you need another hint, these three Austen characters are all suitors for the hand in marriage of three different Austen heroines!
Unless someone posts them here first, I will post the answers to Part Two tomorrow morning EST, along with a remarkable interpretive bonus payoff that relates to one of those three answers.
