I forgot to mention that the deceased AUB Arabic professor, Sami Makarem, is the son of Nasib Makarem, who is in my judgment the best Arab calligrapher of the 20th century. So many of the official letterheads and even inscriptions of flags and logos of Arab states and monarchies were designed by Nasib. The man's original style has influenced all Arab calligraphers who came after him. He was on loan for many wealthy Arab rulers and his art work should be displayed in a museum. His son, Sami, was talented himself and did nice combination of Arab calligraphy with Hallaj poetry.
