What are the motifs in The Master Builder by Henrik Ibsen?

Rejuvenation comes in the form of Hilda, a young woman who sparks Solness's waning creativity and sexuality. When Hilda first comes to the house, Solness admits that he is no longer interested in building homes, for no one appreciates his work. When Hilda tells him that the sight of him climbing the tower in her hometown was "wonderfully thrilling" and "lovely," and reminds him that he kissed her several times that evening, his pride in his work reemerges along with his sense of sexual prowess.
