It is possible that this lamp is of Jerusalem-stone and was fashioned in the Yemenite style, by a Yemenite migrant to the Holy Land. For further discussion in this direction see E. Muchawsky-Schnapper, Oil Sabbath-Lamps and Hanukah Lamps of Stone from The Yemen in: Journal of Jewish Art vol. XI (1982) pp. 76-83 (illustrated). See also Sotheby’s Tel Aviv, 24-25th June, 1997, lot 7, for a related Chanukah lamp.
