Lambert Sustris (c. 1515/1520 – c. 1584) was a Dutch painter active mainly in Venice. The works Sustris completed in Italy exhibit either a Mannerist style or qualities that may be deemed proto-Baroque. He is also referred to as Alberto de Olanda (Albert of Holland). He was born in Amsterdam, and only came to Venice when over 40 years old. His training is unknown, but he was utilized by the studio of Titian for the depiction of landscapes. He accompanied Titian on his trips to Augsburg in 1548 and 1550–1551, and there executed portraits. Returning to Venice, he was influenced by Parmigianino and Andrea Meldolla.
His son was Friedrich Sustris, who he trained. Another pupil was Girolamo Muziano. As the Muziano scholar Patrizia Tosini has noted, Sustris's works, via his pupil Muziano, are a significant means by which a mid-sixteenth century Venetian interest in landscape and its role as a backdrop for historical subjects spread to Rome in the mid-to-late sixteenth century.[1]
