ESTEBANEZ CALDERON, SERAFIN (1799-1867), a Spanish author, best known by the pseudonym of "El Solitario," was born at Malaga on the 27th of December 1799. His first literary effort was _El Liston verde_, a poem signed "Safinio" and written to celebrate the revolution of 1820. He was called to the bar, and settled for some time at Madrid, where he published a volume of verses in 1831 under the assumed name of "El Solitario." He obtained an exaggerated reputation as an Arabic scholar, and played a minor part in the political movements of his time. He died at Madrid on the 5th of February 1867. His most interesting work, _Escenas andaluzas_ (1847), is in a curiously affected style, the vocabulary being partly archaic and partly provincial; but, despite its eccentric mannerisms, it is a vivid record of picturesque scenes and local customs. Estebanez Calderon is also the author of an unfinished history, _De la conquista y perdida de Portugal_ (1883), issued posthumously under the editorship of his nephew, Antonio Canovas del Castillo. ESTELLA, a town of northern Spain, in the province of Navarre, on the left bank of the river Ega, 15 m. W.S.W. of Pamplona. Pop. (1900) 5736. Estella, which occupies the site of a Roman town of uncertain name, contains several monasteries and churches, a medieval citadel, and a college which was formerly a university. Its principal industries are the manufacture of woollen and linen fabrics and brandy-making; and it has a considerable trade in fruit, wine and cattle. Estella commands several defiles on the roads from Castile and Aragon, and on that account occupies a position of considerable strategic importance. It was long the headquarters of Don Carlos, who was proclaimed king here in 1833. In 1873 it was the chief stronghold of the Carlists, and in 1874, when driven from other places, they succeeded in retiring to Estella. On the 16th of February 1876 the Carlists in the town surrendered unconditionally. For an account of the Carlist rising see SPAIN: _History_. ESTERHAZY OF GALANTHA, a noble Magyar family. Its origin has been traced, not without some uncertainty, to Salamon of Estoras, whose sons Peter and Illyes divided their patrimony in 1238. Peter founded the family of Zerhazy, and Illyes that of Illyeshazy, which became extinct in the male line in 1838. The first member of the family to emerge definitely into history was Ferencz Zerhazy (1563-1594), vice lord-lieutenant of the county of Pressburg, who took the name of Esterhazy when he was created _Freiherr_ of Galantha, an estate acquired by the family in 1421. His eldest son, Daniel (d. 1654), founded the house of Czesznek, the third, Pal (d. 1641), the line of Zolyom (Altsohl), and the fourth, Miklos, that branch of the family which occupies the most considerable place in Hungarian history, that of Frakno or Forchtenstein.
