Eustahija Arsić was born in 1776 to the Serbian Cincić family in Irig, then part of the southern Hungary. She had an excellent education and learned to speak several languages, Hungarian, German, Romanian, Church Slavonic, Italian, Latin and some English. Her personal life was an unhappy one, being married and widowed three times. As a young woman she was married to Mr. Lacković, a merchant in Koprivnica, Croatia. Her second husband was Toma Radovanović, a wealthy Serbian merchant in Karlovac who bought his title of nobility from the Viennese court. In the first years of the 19th century, she married her third husband, nobleman Sava Arsić who was a longtime senator and mayor of Arad, great benefactor of Arad's school for teachers, and a patron of Serbian writers of that time. It was after their marriage that Eustahija began her literary work. She was an important patron of the literary efforts of her contemporaries and was probably better known in her lifetime for this activity than for her own writings. One of the most popular places for the exchange of ideas was the salon in those days. Eustathija Arsić's home in Arad had a reading room, often galvanized by the presence of political and other émigré Serbs, including Dositej Obradović. She was highly regarded by dramatist Joakim Vujić, who called her "ma seule protectrice". Vuk Karadžić sought her favours in promoting his books, and many other Serbian and Romanian authors did the same. Evstahija Arsić's sparse writings has been highly praised. Much of it deals with moral teachings, short pieces of advice, and philosophical reflections. Her works, published somewhat anachronistically, in 1814, 1816, and 1829, are entirely in keeping with the spirit of the Enlightenment. She refers frequently to the example of Dositej, her model of a committed instructor of his people. Her writings are thoughtful, eloquent, serious and direct. They suggest an impressive mind and deep commitment at a time when it was quite unknown for a Serbian woman to be engaged in any kind of literary activity, let alone the promotion of other authors's works, while at the same time, producing her own opus. In his book "Traveling through Serbia in the Year 1829", Otto Ferdinand Dubislav von Pirch mentions that Arsić has translated works by Voltaire, Wieland and James Thomas.
