Prophet arrived in Paris in August of either 1921 or 1922 and obtained a studio on Avenue du Chatillon in Montparnasse. In the Fall of 1922 or 1923 to the Spring of 1924 or 1925, she studied with Victor Joseph Jean Ambroise Segoffin at the École des Beaux-Arts, a sculptor noted for his statues, tombs, and portrait busts. Under his mentorship, she created two different busts, one of which was exhibited at the Salon d'Automne in 1924. It is thought that because the Salon was at that time more rigid in acceptances, Prophet most likely avoided radical themes in her work, and avoided avant-garde work in order for her sculpting to be shown. She later left the École because she believed she could teach herself faster than working under a supervisor, and she bought her own sculpting tools, doing all the carving with no assistance due to her lack of funds. Prophet also studied woodcutting under Oscar Waldmann, a Swiss German sculptor, and marble cutting from Kousouski, a Polish sculptor.
