The greek Drákaines (Δράκαινες) is a race or group of serpent-like creatures with human features, generally female. Basically what the Medusa from the original 80's Clash of the Titans, minus the snakes for hair. The singular name is drakaina (Δρακαινα), and the latin name is dracaena. Does anyone know the name of any other mythological creatures, from any other regions, such as ancient Egypt, Persia, China, or Japan, with the same description, a creature which is upper half human, lower half serpent?
δράκαινες is simply the Nominative plural form of δράκαινα (drákaina), which is composed of δράκων (drákōn, “dragon”) + -αινᾰ (-aina). From Byzantine Greek δράκαινα (drákaina), feminine form of δράκων (drákōn), i.e. a female dragon.
In Greek mythology, a drakaina is a female serpent or dragon, sometimes with humanlike features. It is not recorded to be a different race from drákōn.
Python, slain by Apollo, and the earliest representations of Delphyne are shown as simply gigantic serpents, similar to other Greek dragons.
