CȲMA (κῦμα), in architecture, an _ogee_, a wave-shaped moulding, consisting of two curves, the one concave and the other convex. There were two forms, the _cyma recta_, which was concave above, and convex below, thus, [Illustration], and the _cyma reversa_, which was convex above and concave below, thus [Illustration]. The diminutive _cymatium_ or _cumatium_ (κυμάτιον) is also used, and is indeed the more common name. CYMBA (κύμβη) is derived from κύμβος, a hollow, and is employed to signify any small kind of boat used on lakes, rivers, &c. It appears to have been much the same as the _acatium_ and _scapha_. [Illustration: Cymbala. (From a Bas-relief in the Vatican.)] CYMBĂLUM (κύμβαλον), a musical instrument, in the shape of two half globes, which were held one in each hand by the performer, and played by being struck against each other. The word is derived from κύμβος, a hollow. The cymbal was a very ancient instrument, being used in the worship of Cybelé, Bacchus, Juno, and all the earlier deities of the Grecian and Roman mythology. It probably came from the East. The crotalum (κρόταλον) was a kind of cymbal. It appears to have been a split reed or cane, which clattered when shaken with the hand. Women who played on the crotalum were termed _crotalistriae_. Such was Virgil’s Copa: “Crispum sub crotalo docta movere latus.” The line alludes to the dance with crotala (similar to castanets).--For _sistrum_, which some have referred to the class of _cymbala_, see SISTRUM. [Illustration: Crotala. (Borghese Vase now in the Louvre.)] DACTỸLUS (δάκτυλος), a Greek measure, answering to the Roman _digitus_, each signifying a _finger-breadth_, and being the sixteenth part of a foot. [PES.] DAEDALA or DAEDĂLEIA (δαίδαλα, δαιδάλεια), names used by the Greeks to signify those early works of art which were ascribed to the age of Daedalus, and especially the ancient wooden statues, ornamented with gilding and bright colours and real drapery, which were the earliest known forms of the images of the gods, after the mere blocks of wood or stone, which were at first used for symbols of them. DAEDĂLA (δαίδαλα), the name of two festivals, celebrated in Boeotia in honour of Hera, and called respectively the _Great_ and the _Lesser Daedala_. The latter were celebrated by the Plataeans alone; in the celebration of the former, which took place only every sixtieth year, the Plataeans were joined by the other Boeotians. DAMARĔTĪON (δαμαρέτειον χρύσιον), a Sicilian coin, respecting which there is much dispute; but it was probably a gold coin, equal in value to fifty litrae or ten Attic drachmae of silver; that is, a half stater. DAMIURGI. [DEMIURGI.] DAMŎSĬA. [EXERCITUS.] DANĂCE (δανάκη), properly the name of a foreign coin, was also the name given to the obolos, which was placed in the mouth of the dead to pay the ferryman in Hades.
