In literature, the word “hand” is a highly versatile symbol that can denote physical contact, emotional intimacy, or even abstract notions of agency and fate. For instance, authors use the act of seizing and kissing a lover’s hand to convey passion and urgency, as seen in Chekhov’s depiction in [1] and again in Andersen’s tender moment in [2]. Meanwhile, the hand functions as a marker of etiquette and ritual, whether it is used to greet respectfully, as in Tolstoy’s gentle kiss in [3], or to secure alliances and convey promises in works like King Lear [4] and biblical texts [5, 6, 7]. Even in moments of inner turmoil or metaphorical expression—such as Wilde’s imagery of a “hand of ice” over one’s heart in [8]—the hand remains a powerful emblem of both human vulnerability and strength.
