[1][2] Jonas Aleksandravičius was born on 7 July 1904 in the village of Kampiškės [lt] of the modern-day Kaunas district, then part of the Russian Empire.

[1][3][4][5] In 1927 Aistis began his Lithuanian studies at the Vytautas Magnus University in Kaunas, meanwhile working as a clerk for the Agriculture Bank (Žemės bankas [lt]).

In 1946 Aistis moved to the United States, working at the Marianapolis college where he lectured the Lithuanian, French and Spanish languages.

That same year Aistis moved to New York and began working with the National Committee for a Free Europe, collecting analytical reviews of Lithuanian newspapers and books.

Aistis wrote about themes such as the opposition of the ideal and reality, modern expressions of traditional rural worldliness, and the stylistics of emotional confession.

The foreboding of the coming historical catastrophe of Europe and the occupation of Lithuania is conveyed by romantic images of the Middle Ages and motifs of Lithuanian history.
