Gaetano Martoriello (c. 1680–1733)[1] was an Italian painter of the late-Baroque period, active in his natal city of Naples. He painted mainly marine vedute and landscapes.[2] He initially trained under Giacomo del Po, but desiring to paint landscapes he worked under Nicola Massaro, who claimed to have trained under Salvatore Rosa.[3] He is also said to have worked under Francesco Solimena, after the later painter rebuked Martoriello for criticizing some paintings by the German landscape artist, Francesco Joachim Beich.[4]
