Ricciardo Amadino (fl. 1572–1621) was a Venetianprinter. He briefly attempted to publish music on his own in 1579, but was unsuccessful. He joined with Giacomo Vincenti, with whom he published over 80 books between 1583 and 1586. Many of these were re-prints of popular madrigal books, but some were first printings. Their partnership ended around 1586, but they continued to work together occasionally. After 1586, Amadino's mark was a woodcut of an organ, and he printed primarily music, with a few theoretical treatises, including the first edition of Ercole Bottrigari's Il desiderio. He printed editions of such important composers as Luca Marenzio and Claudio Monteverdi, including the celebrated 1609 edition of L'Orfeo, and in terms of sheer output was one of the foremost Italian music printers.
