Dainas are very short, usually only one or two stanzas, unrhymed and in a four-footed trochaic metre. Lyrically, dainas concern themselves with native mythology but, in contrast to most similar forms, do not have any legendary heroes. Stories often revolve around pre-Christian deities like the sun goddess Saule, the moon god Mēness and, most notably, the life of people, especially its three most important events - birth, wedding and death (including burial). The first collection of dainas was published between 1894 and 1915 as "Latvju Dainas" by Krišjānis Barons.
