During his time in Mantua, Vivaldi became acquainted with an aspiring young singer Anna Tessieri Girò, who would become his student, protégée, and favorite prima donna. Anna, along with her older half-sister Paolina, moved in with Vivaldi and regularly accompanied him on his many travels. There was speculation as to the nature of Vivaldi's and Girò's relationship, but no evidence exists to indicate anything beyond friendship and professional collaboration. Vivaldi, in fact, adamantly denied any romantic relationship with Girò in a letter to his patron Bentivoglio, dated 16 November 1737.
