About Eleazar ibn Shmuel al-Hurga, Alluf al-Andalus & Resh Kallah
The oldest evidence of correspondence between the gaons of Babylon and the rabbis of Lucena and Barcelona dates back to the mid 9th century.
It is the late 9th century when Eleazar ibn Samuel Hurga, one of the most prominent Spanish Jewish scholars of the time, conducts his work in Lucena.
He corresponded with the gaons of Babylon from Lucena on a regular basis. He travelled there to join the circle of the most important Hebrew intellectuals of the age and resided for a time in Sura, where he was given the titles of alluf of Spain and resh kalla, in recognition of his science and learnedness.
