Heathcliffe and Rochester are both black-avised, stubborn of countenance, negligent as to external appearance, moody, proud in carry, and morose. Charlotte Brontë tells us of one that on external judgment "most people would have thought him" possessed of a disqualification, and of the other that "some people might suspect him" of having a disqualification. And in each case a similar offset—the internal reading of the man's character—is brought forth by Charlotte Brontë as Lockwood or Jane:—"A sympathetic cord within" tells the former that Heathcliffe's reserve read as under-bred pride springs from an aversion to "manifestations of mutual kindliness"; and Jane, commenting on Rochester's being proud and sardonic, says, "In my secret heart I knew ... his kindliness to me was balanced by unjust severity to others."
I find the singular expression indicated by the "hell's light" epithets applied to Heathcliffe's eyes was an expression Charlotte Brontë had apparently noticed in the original of this character. Rochester's eyes in Jane Eyre have "strange gleams," and we are told "his eye had a tawny—nay, a bloody light in its gloom," and so forth. Indeed, Heathcliffe's eyes, which were "clouded windows of hell" with "black-fire in them," are seen in Rochester's clearly enough, and the singular "hell's light" is associated with them at considerable length, in
Jane Eyre:—
And as for the vague something—was it a sinister or a sorrowful ... expression?—that opened upon a careful observer ... in his eye, and closed again before one could fathom the strange depth partially disclosed; that something which used to make me fear and shrink, as if I had been wandering amongst volcanic-looking hills, and had suddenly felt the ground quiver and seen it gape.
The following description of Heathcliffe could be read as of Rochester, whose "olive cheek" and "deep eyes" Jane describes:—
Wuthering Heights.
His cheeks were sallow and half-covered with black whiskers, the brows were lowering, the eyes deep-set and singular. I remembered the eyes. His upright carry suggested his having been in the army [M. Héger had fought as a soldier] ... His countenance ... looked intelligent. A half-civilized ferocity lurked in the depressed brows and eyes full of black fire, but it was subdued, and his manner was even dignified, though too stern for grace.
In view of the general evidence that Heathcliffe, like Rochester, was drawn by Charlotte Brontë from M. Héger, her Brussels friend the professor, it is not surprising that Heathcliffe's was "a deep voice and foreign in sound." Her reference in Wuthering Heights to his Spanish extraction reminds us of M. Paul Emanuel's "jetty hair and Spanish face" in Villette, and of course it is well known M. Paul Emanuel was drawn by Currer Bell from M. Héger.
