As for Arthur, he seemed under a spell; moving his hands from his face, he opened wide his arms. She was leaping for them, when Van Helsing sprang forward and held between them his little golden crucifix. She recoiled from it, and, with a suddenly distorted face, full of rage, dashed past him as if to enter the tomb.

– Bram Stoker

Dracula, Chapter 16. When Lucy appears as a voluptuous and sexy vampire to Arthur Holmwood and the others, Arthur is passively drawn to the creature who beckons him to come with her. That is until Van Helsing intervenes with his crucifix to repel her.
