A genus of a family (Didunoulid*) of pigeons, peculiar to Samoa, and characterized hy a hooked ujjper mandihle and a toothed lower one — the tooth- billed pigeons. See Pigeon". DIDYM'IUM iNeo-Lat., from Gk. dlovm didynius, twin, from Si-, di-, double + Sio, dyo, two; .so called from being found in the same min- eral which yields lanthanum). A metal discov- ered in 1842 by ilosander. in the mineral cerite. It is also found in gadolinitc. orlliile. and other cerium minerals. Kccent investigations have shown tlial didymium consists of two elements, neodymiuin (.symbol Xd.. atomic weight 144), and praseodymium (.symbol Pr., atomic weight 140). DICYMUS (Lat., from Gk. StSvfux, twin). The Greek translation of the Hebrew name of Thomas, one of the twelve disciples of Jesus, the Greek form of the name Quticis, Thomtis, from which the English name is transliterated, being itself a transliteration of the Hebrew word Thi'imu, the meaning of which is 'a twin' (Gen. XXV. 24: xxwiii. 27: Song of Solomon iv. 5, vii. 3). This translation of the name is found only in the Fourth Gospel (xi. Hi, xx. 24. xxi. 2— "Thomas, called Didymus"). where it was most appropriately used, in view of the Greek-speaking Christians of Asia Minor, for whom the Gospel was written. See TiioM.vs, Apo.stle. DIDYMUS (Lat.. from Gk. A'Sv^oi;) (B.C. 03 — ?). An Alexandrian grammarian of the time of Augustus. Didynius is famous as author of an enormous number of books, in which he embraced the works of his predecessors, and also as the man who transjdanted learning from Alexandria to Rome. The total number of his works is given as 3.)00 by Athemeus and Suidas; Seneca says 4000. These include connnentaries on Homer. Hesiod. Pindar. Bacehylides, .Kschylus, Sophocles, Euri- pides, Eupolis. Cratinus, Aristophanes, Jlenan- der. Antiphon. Isieus, .Esehines, Demosthenes. Hyperides, and many others. The extant scholia to Homer, Pindar, Sophocles, Euripides, and Aris- tophanes, in great measure, go back to his com- mentaries. He also published lexicographical collections on the poets, historians, and orators; wrote on all kinds of questions concerning lit- erary history and composition: and composed historical and anti<|uarian treatises. From his endless industry he was nicknamed Chaleenter- os ( XaKKlvTei)os ). 'Bronzegut.' and. likewise 'The forgetter of books," pifiXiriKieas, since he for- got some of his owti productions. Among the Romans he was in such high repute thjit Macro- bins called him the most learned grannnarian of his own or other times.
