Why by ‘Jusquin’? Towards a stylistic contextualisation of Ave festiva ferculis

What lies behind an attribution to a well-known composer in an otherwise peripheral MS for his surviving repertory? Whilst the current consensus is that Ave festiva ferculits – an unusual setting of a Marian responsory – was misattributed to Josquin in Tarazona 2/3, this paper will attempt to contextualise its style and structure by showing a number of contrapuntal and even intriguing motivic relationships with music composed outside the Iberian Peninsula during the later decades of the 15th century, including by Josquin himself. This enquiry further, therefore, brings forward the question of how and where the composer might have known this music, and when and where the motet might have been written.
