The Gratulationes Valdinenses is one of the extant Latin works of Gabriel Harvey, published in 1578, and first referred to in the gloss to the September Eclogue of the Shepheardes Calendar in the following year:
Mayster Gabriel Harvey: of whose speciall commendation, as well in poetrye as rhetorike and other choyce learning, we have lately had a sufficient tryall in diverse his workes, but specially in his Musarum Lachrymae, and his late Gratulationum Valdinensium, which boke, in the progresse at Audley in Essex, he dedicated in writing to her Majestie, afterward presenting the same in print unto her Highnesse at the worshipfull Maister Capells in Hertfordshire.
