Among Maranta's most-referenced works is his treatise on antidotes to poisons, Della theriaca et del mithridato, in two volumes (1572).
Ephraim Chambers, in his 1728 Cyclopaedia, says "Mithridate is one of the capital Medicines in the Apothecaries Shops, being composed of a vast Number of Drugs, as Opium, Myrrh, Agaric, Saffron, Ginger, Cinnamon, Spikenard, Frankincense, Castor, Pepper, Gentian, &c".
He wrote important works on the ancient kingdoms of Asia Minor–Trois royaumes de l'Asie Mineure, Cappadoce, Bithynie, Pont (1888), Mithridate Eupator (1890); also a critical edition and translation with H Weil of Plutarch's Treatise on Music; and an Histoire des Israélites depuis la ruine de leur indépendance nationale jusqu'à nos jours (2nd ed., 1901).
