Pieguļa ([pieguʎa]; in Latvia) or naktigonė (in Lithuania) was an ancient tradition of grazing common types of horses during night, that existed about until the early 20th century.
After winter, the grazing horses were released on their own for the first time, while under the shepherds (pieguļnieki) supervision.
Several khutor guys often rode to pieguļa together, who stayed overnight at grazing along with their horses.
Pieguļa riding was also linked with a wide range of folklore layers, innumerable folk songs and beliefs.
Different periods were entirely described poetically and imaginatively by many Latvian writers (e.g. J. Jaunsudrabiņš White Book).
