Pseira Pseira (Greek Ψείρα) is an islet in the Gulf of Mirabello in northeastern Crete with the archaeological remains of Minoan and Mycenean civilisation. The island was explored in 1906–07 by Richard Seager and partially documented by Halvor Bagge in ink and watercolors based on photographs (University Museum, University of Pennsylvania, 1910), and more minutely examined in 1984–92 by Philip P.
