Pedanius Dioscorides
The extinct Dacian language has left few traces, but in "De Materia Medica" by Pedanius Dioscorides, a plant called "Strychnos alikakabos" (Στρύχνος άλικακάβος) is discussed, which was called "kykolis" (or "cycolis") by the Dacians. Some have considered this plant to be "P. alkekengi", but the name more likely refers to ashwagandha ("Withania somnifera").
