Terebinthus (also Terebinthus of Turbo ) was a suggested pupil of Scythianus, during the 1st-2nd century CE, according to the writings of Christian writer and anti-Manichaean polemicist Cyril of Jerusalem, and is mentioned earlier in the anonymously written, critical biography of Mani known as Acta Archelai.
According to Cyril's anti-Manichaean works and in other Orthodox polemic, Terebinthus went to Judaea and later returned to Syria Palaestina ("becoming known and condemned" there), and ultimately settled in Babylonia. He is also said to have brought with him the books of Scythianus, which he presented upon his death to his lodger, a widow with a slave named Cubricus, who later changed his name to Mani. Mani allegedly studied the books, which thereby become the source of Manichean doctrine.
This story can be found also in Acta Archelai, an anti-manichean scripture written in Syriac language, which is ascribed to the late 4th-century CE writer Hegemonios.
Later the same is mentioned in Lexicon Suidae (10th century) in an article dedicated to Mani. According to the Lexicon, the names of the books were: Mysterium, Evangelium, Thesaurum and Capitum (meaning "Mystery", "Gospel", "Treasury", and "Book of Chapters" respectively).
The connection between Mani and Buddha is also mentioned in a letter of Marius Victorius (4th century CE) Ad Justinum Manichaeum.
