Zechariah Dhahiri
Zechariah (Yaḥya) al-Ḍāhirī (, , b. "circa" 1531 – d. 1608), often spelled Zechariah al-Dhahiri () (16th century Yemen), was the son of Saʻīd (Saʻadia) al-Ḍāhirī, from Kawkaban, in the District of al-Mahwit, Yemen, a place north-west of Sana’a. He is recognized as one of the most gifted Yemenite Jewish poets and rabbinic scholars who left Yemen in search of a better livelihood, travelling to Calicut and Cochin in India, Hormuz in Persia, Basra and Irbīl in Babylonia, Bursa and Istanbul in Anatolia, Rome in Italy, Aleppo and Damascus in Syria, Safed and Tiberias, as well as Jerusalem and Hebron in the Land of Israel (then part of Ottoman Syria), Sidon in Ottoman Lebanon and Egypt, and finally unto Abyssinia where he returned to Yemen by crossing the Erythraean Sea and alighting at a port city near Mocha, Yemen. He wrote extensively about his travels and experiences in these places, which he penned in a Hebrew rhymed prose narrative, and eventually publishing them in a book which he called Sefer Ha-Mūsar ("The Book of Moral Instruction"), in circa 1580.
Exilarch
Only a single entry has been preserved regarding the later fortunes of the exilarchate. When Gaon Hai died in 1038, nearly a century after Saadia's death, the members of his academy could not find a more worthy successor than the exilarch Hezekiah, a descendant, perhaps a great-grandson, of David ben Zakkai, who thereafter filled both offices. But two years later, in 1040, Hezekiah, who was the last exilarch and also the last "gaon", fell a victim to calumny. He was imprisoned and tortured to death. Hezekiah, is counted as the last exilarch and also the last "gaon". Two of his sons fled to Spain, where they found refuge with Joseph, the son and successor of Samuel ha-Nagid. However, "Jewish Quarterly Review" mentions that Hezekiah was liberated from prison, and became head of the academy, and is mentioned as such by a contemporary in 1046.
