The lotiform beaker appears to be influenced by Achaemenid petalled bowls in metal and glass, cf. S. M. Goldstein, Pre-Roman and Early Roman Glass in The Corning Museum of Glass, New York, 1979, pp. 118-119, nos. 248-250; it is also similar to Hellenistic silver vessel prototypes, cf. A. Oliver, Silver for the Gods, Toledo, 1977, no. 47; see Goldstein, op. cit., p. 134, no. 277 and D. B. Harden et al, Masterpieces of Glass, The British Museum, London, 1968, p. 32, no. 36 for Hellenistic glass petalled bowls; and D. F. Grose, The Toledo Museum of Art: Early Ancient Glass, New York, 1989, p. 179 and 204, no. 211 for a Hellenistic glass fluted bowl.
