Your understanding that the portrayal of the Báb and
Bahá'u'lláh in works of art is forbidden is correct. The Guardian made it clear
that this prohibition refers to all the Manifestations of God; photographs, or
reproductions of portraits, of the Master may be used in books, but no attempt
should be made to portray Him in dramatic or other works where He would be one of
the "dramatis personae". However, there can be no objection to
symbolic representation of such Holy Figures, provided it does not become a
ritual and that the symbol used is not irreverent.
