\Au*gus"tan\, a. [L. Augustanus, fr. Augustus. See
{August}, n.]
1. Of or pertaining to Augustus C[ae]sar or to his times.
2. Of or pertaining to the town of Augsburg.
{Augustan age} of any national literature, the period of its
   highest state of purity and refinement; -- so called
   because the reign of Augustus C[ae]sar was the golden age
   of Roman literature. Thus the reign of Louis XIV. (b.
   1638) has been called the Augustan age of French
   literature, and that of Queen Anne (b. 1664) the Augustan
   age of English literature.
{Augustan confession} (Eccl. Hist.), or confession of
   Augsburg, drawn up at Augusta Vindelicorum, or Augsburg,
   by Luther and Melanchthon, in 1530, contains the
   principles of the Protestants, and their reasons for
   separating from the Roman Catholic church.
