IXTACCIHUATL, or Iztaccihuatl (“white woman”), a lofty mountain of volcanic origin, 10 m. N. of Popocatepetl and about 40 m. S.S.E of the city of Mexico, forming part of the short spur called the Sierra Nevada. According to Angelo Heilprin (1853-1907) its elevation is 16,960 ft.; other authorities make it much less. Its apparent height is dwarfed somewhat by its elongated summit and the large area covered. It has three summits of different heights standing on a north and south line, the central one being the largest and highest and all three rising above the permanent snow-line. As seen from the city of Mexico the three summits have the appearance of a shrouded human figure, hence the poetic Aztec appellation of “white woman” and the unsentimental Spanish designation “La mujer gorda.” The ascent is difficult and perilous, and is rarely accomplished.
Heilprin says that the mountain is largely composed of trachytic rocks and that it is older than Popocatepetl. It has no crater and no trace of lingering volcanic heat. It is surmised that its crater, if it ever had one, has been filled in and its cone worn away by erosion through long periods of time.
IYRCAE, an ancient nation on the north-east trade route described by Herodotus (iv. 22) beyond the Thyssagetae, somewhere about the upper basins of the Tobol and the Irtysh. They were distinguished by their mode of hunting, climbing a tree to survey their game, and then pursuing it with trained horses and dogs. They were almost certainly the ancestors of the modern Magyars, also called Jugra.
The reading Τῦρκαι is an anachronism, and when Pliny (N.H. vi. 19) and Mela (i. 116) speak of Tyrcae it is also probably due to a false correction.

IZBARTA, or Sparta [anc. Baris], the chief town of the Hamid-abad sanjak of the Konia vilayet, in Asia Minor, well situated on the edge of a fertile plain at the foot of Aghlasun Dagh. It was once the capital of the Emirate of Hamid. It suffered severely from the earthquake of the 16th-17th of January 1889. It is a prosperous place with an enlightened Greek element in its population (hence the numerous families called “Spartali” in Levantine towns); and it is, in fact, the chief inland colony of Hellenism in Anatolia; Pop. 20,000 (Moslems 13,000, Christians 7000). The new Aidin railway extends from Dineir to Izbarta via Buldur.
