Klimt returned to the theme of 'sensual women in water' in two works know as Water Serpents I and Water Serpents II. Water Serpents I is not an oil painting, and its pale, unusual colouring is in part dictated by the medium used. It does not differ much from the preliminary drawings that Klimt used for reference, apart from the addition of the gold paint, and the green and gold-leaf thread entangled around the women's bodies. The unambiguously lesbian embrace of his models would perhaps have been unacceptable had it been presented as a straight portrait. However, by renaming the work and giving it an allegorical theme and by adding the fish-like serpent behind the bodies and adorning every surface with gold and pattern, Klimt was able to show the painting to Vienna without fear of censorship.
