TTBANGI. 608 UCCELLO. From its mouth to its confluence with the ]Mboniu at Yakoma, about 22° 40' E., the Ubangi forms the boundarj- between Frencli Congo and the Congo Free State. That part of the river known as the Welle was first discovered bj- Schweinfurtli in 1S70; some ten years later Junker explored the Makua ; in 1884 Hanssens discovered tlic mouth of the Mobangi; in 1885-86 Grenfell went up as far as the Zongo rapids, and within half a dozen years the several parts of the river already discovered were identified as the Ubangi. In great part the river flows through a populous country. Ubangi is also the name of a district in the northwestern part of the Congo Free State. UBASTET. An Egj'ptian goddess, called also Pasht or Pakbt and, from the Greek form of the name of the city where she was especially worshipped, Bubastis or Bast. She was the wife of Ptah (see Memphi.s), and was identified by the Greeks with Artemis (see DlAX.). Her son was Tum, the solar deity of the western horizon. Beside her main seat of worship at Bubastis (q.v.) she was honored at Thebes (q.v. ) and together with Ptah, at Jlemphis. Ufbastet is usually represented as a woman with a cat's head, but in the earlier monuments she more frequently has the head of a lion. Her annual festival, held at Bubastis, was characterized by revelry which implies by its phallic accom- paniments a fcrtility-conce])t in the nature of the goddess. The cult of Ubastet does not appear to have been very ancient, but from the reign of Rameses III. (q.v.), in the thirteenth century B.C., it became one of the most imi)ortant in Egj-pt. See Bubastis. and for illustration see Pa'khl in the plate of Egyptian Deities in the article Egypt. TJBEDA, oo-Ba'Da. A Spanish town of the Province of Jaen. in Andalusia, in the midst of the fertile Loma de Ubeda. It is 74 miles east of Cordova (Map: Spain. D 3). The country abounds in vineyards, olive ])lantations, and pasturages devoted especially to the rearing of horses. The town contains a castle with more than twenty towers, the sixteenth-century Church of San Sal- vador, and the Gothic San Pablo and San Nicolas of lesser note, together with the Palacio de las Cadenas, in which are the municipal offices and the edifice of the Colegio de Escolapius. The streets are broad and well paved and with the plazas well kept. The chief manufactures are pottery, leather, soap, and woolens. The popu- lation in 1000 was 19,395. UBERTI, oo-ber'te. Fazio degli (c.1310- C.1370?). An Italian poet, born probably in Pisa. His love lyrics show the influence of Petrarch. His political verse is strongly Ghibelline in senti- ment and bitter against the Papacy. His most noted work is the unfini.shed didactic poem entitled Diftdiiioiuln (i.e. dicia mundi. or things worthy of note in the world), which in its methods imitates the Diiina Commedia of Dante. Like Dante, converted to righteousness in the middle of the path of life, Fazio feigns himself guided on a fantastic journey by the an- cient geographer Solinus, from whose work he borrows largely. He traverses nearly all the known world save Asia, and in connection with all that he imagines himself as seeing he nar- rates fables, traditions, and legends which imitate, but poorly, episodes of Dante's poem. Consult the first edition of the Dittnmondo (Vicenza, 1474) and that of Jlonti and Perticard (Jlilan, 182(i) ; an edition of the hirichc editc e iiiedite (Florence, 1883) was prepared by Ke- nier. A commentary on the UUtuinondo by G. Cappello (1437) remains unedited. TTBIQUIST (from Lat. ubiqiie, everywhere). A plant which grows in practically all habitats. The conunon dandelion, which grows naturally in light or shaded, moist or dry conditions, may be regarded as a typical example. The term cos- mopolite refers to existence in all climates rather than all habitats. UBIQUITY (from Lat. uhique, everywhere, from uhi, where). A term applied in theology to the doctrine that the Lord's body, in conse- quence of its personal union with the divine, by a 'communication of properties.' is everywhere present. This use of the word has its origin in the teachings of Luther, who, to defend the real presence of the entire Christ in, with, and under the elements of the Lord's Supper, taught consist- ently that Christ's body could be everywhere, al- though be called this presence 'illocal.' UCAYALE or UCAYAIil, nri'ki-ii'le. A large river of Peru (Map: Peru, C 5). It is one of the main headstreams of the Amazon, and, judged by length and volume, it should be con- sidered as the true upper course of that river. It is formed by the junction of the Apurimac (q.v.), or Tambo, and the Quillabamba at the eastern base of the Andes on the boundary be- tween the departments of .Jnnin and Cuzco, and flows northward in a much winding course till it joins the Marafion in the northeastern corner of Peru to form the Amazon. The length of the Ucayale proper is about 1000 miles, and with the Apurimac the total length is nearly 1500 miles. Some of their sources are near Lake Titi- caca, while that of the Mantaro, a tributary of the Apurimac. is in Lake Chinchaycocha or Jn- nin (q.v.) within 100 miles of Lima, on the Pa- cific coast, and over 13,000 feet above the sea. So rapid is their flow, however, that at their con- fluence the LTcayale proper is less than 1000 feet above sea level. From this point its course through the densely forested an<l sparsely popu- lated montano is very sluggish, falling only 500 feet in nearly 1000 miles. Its banks are here very low. and it divides repeatedly into side chan- nels, while large adjacent areas are periodically submerged. The I'cayale is navigable for the largest vessels, maintaining a depth of 40 to 70 feet for over 600 miles. Steamers can also ascend the Pachitea. the principal tributary below the confluence of the headstreams, over 200 miles to a point about 300 miles from Lima and 3fi00 miles from the mouth of the Amazon. The LTcayale thus affords an easy means of communi- cation between the Atlantic Ocean and the heart of Peru. UCCELLO, oC-chel'16, or UCCELLI, Paolo (C.1397-C.1475). A Florentine painter of the Re- naissance, the fir.st of the naturalists. He was properly Paolo di Dono by name, but was called Uecello on account of his fondness for birds. He was a pupil of Ghiberti and was also in- fluenced by Donatello and by Domenico Venezi- ano. Under Manetti lie acquired the facility in perspective which liecame the main feature of his work. His rare paintings arc found chiefly ia
