The Gude and Godlie Ballatis is a collection of religious lyrics from the early years of the Scottish Reformation. It was a highly popular, if controversial, volume, was often reprinted, and is considered one of the most important literary works of vernacular Scots from the period. It contains translations of a number of Psalms, but most of the contents consist of shorter songs and ballads, many of which have been adapted from a secular to a spiritual use. The previous edition of the collection dates from 1897. The new edition not only revises the information given there, but presents the text of the earliest print (1565), which was unknown to the previous editor. The textual development of the collection through the various printings is studied, and is related to the changing historical, political, literary, cultural and theological contexts of Reformation Scotland. The editor addresses questions of authorship, transmission, source material, and the use and significance of these lyrics. Drawing on recent work in book history and English psalmody, as well as a deep knowledge of Older Scots lyric, he demonstrates the close connections between the collection and Continental hymnody, as well as interactions with English and Scots lyric, both sacred and profane.
