I was reading Dickens' 'Hard Times' and noticed in the descriptions of Mrs Sparsit that Dickens describes first her nose and then her eyebrows as "Coriolanian". What on earth are "Coriolanian eyebrows"? They are first described as "dense black eyebrows" (Chapter VII) but is there more to a Coriolanian eyebrow than this and does it refer to Coriolanus or Corioles? I don't remember any descriptions of eyebrows in Shakespeare's play but I could be wrong.
Please help satisfy my curiosity.
