He was nicknamed מסיח by the Ercolian Karaites.
He is admired in Karaite sources such as for example Elijah Hadasi but his followers are criticized for abandoning him and changing his teachings to comply with Christian ideas.

Unlike Karaite sources which criticize Queen Helene, the Jewish sources speak in complementary terms about her.
