Joseph ben Solomon Ṭaiṭazaḳ, also referred to by the acronym "MahaRITaTS", was a talmudic authority and kabalist who lived at Salonica in the 15th and 16th centuries. With his father and his brother he went in 1492 from Spain, his native land, to Salonica, where he became rabbi. He was considered one of the greatest Talmudists of his time, even Joseph Caro invoking his authority ("Abḳat Rokel," § 56). Wikipedia
