Pierre Restany, “Sorel Etrog”, London/Munich, 2001, pages 32-33
Sorel Etrog worked simultaneously in two styles within his celebrated Hinges series, which was rare for the artist; these two categories were labeled Introverts and Extroverts. While Introvert sculptures are geometric abstractions that incorporate hinges, “Piéton Study”
is categorized as an Extrovert, which are sculptures described as “employing hinges as an articulation device.” They resemble active walking figures “concerned with open space and implied movement,” as explained by Etrog. These Extrovert sculptures would evolve to become the various walking figures for which Etrog is most celebrated.
