The Codex Speciálník is a 15th-century speciálník (i.e., special songbook) originating from a monastery in the region of Praha (Prague). Its eclectic mix of Medieval and Renaissance a cappella sacred music is matched only by its briliant juxtapositions of well-known and obscure pieces and composers. Containing works for two, three, and four voices, the Codex is a treasure trove for musicologist and musician alike.
Publication date and place: ca. 1450 – Manuscript.
