It is perhaps still true that research into sacred types of music in early seventeenth-century Italy lags behind that into madrigal, monody and opera; it is certainly the case that the textual aspects of sacred music, themselves closely bound up with liturgical questions, have not so far received the kind of study that has been taken for granted with regard to the literary texts of opera and of secular vocal music. This is hardly to be wondered at: unlike great madrigal poetry or the work of the best librettists, sacred texts do not include much that can be valued as art in its own right. Nevertheless, if we are to understand better the context of the motet – as distinct from the musical setting of liturgical entities such as Mass, Vespers or Compline – we need a clearer view of the types of text that were set, the way in which composers exercised their choice, and the way such taste was itself changing in relation to the development of musical styles. For the motet was the one form of sacred music in which an Italian composer of the early decades of the seventeenth century could combine a certain freedom of textual choice with an adventurousness of musical idiom.
