Eyebrows, Facial Expression, and "Poem to the Eyebrow (Blason du Sourcil)"

This review aims to introduce the role of facial expression in communication, the areas involved in facial expression especially the eye and eyebrow, the "Poem of the Eyebrow" (Blason du Sourcil), and preferred brow archetypes.The ability to interpret and respond properly to facial expressions contributes to emotional self-competence and satisfactory social and cognitive development. Certain areas may intensify the emotional message, clarifying the expression and reducing ambiguity. Specific facial areas might make expressions more difficult to interpret. The region of the eye is the most prominent facial region for emotion interpretation. Roles of eyebrow density and position in the interpretation of facial expression of emotion depend, at least in part, upon the emotion being expressed. For face recognition, the eyebrows may be at least as influential as the eyes.French poet Maurice Sceve wrote "Poem to the Eyebrow." This poem contains some noteworthy verses about the function of the eyebrow: Eyebrow that makes the boldest fearful, and gives courage to even cowards.Among brow archetypes, "Anastasia type" (brow starts on a perpendicular line drawn from the middle of the nostril, arches on a line drawn from the center of the nose through the center of the pupil, and ends on a line drawn from the edge of the corresponding nasal ala through the outer edge of the eye) was the most preferred. The middle brow height was most preferred (the distance from the lateral canthus to the lateral end of eyebrow is two-thirds of the eye width).
