Bibliography (in progress):

• Acta sanctorum June 5, pp. 405 ff., where the Greek (Ζηνᾶς (Ζηνᾶς ὁ δοῦλος)) matches that of Tit 3:16, which is where my middle name comes from, via my uncle Zenas Arthur and my grandfather Zenas Elias Perisho, whose parents were promised that if they would name their son after him, the Quaker missionary to Cuba Zenas L. Martin, who, according to Hiram L. Hilty in Quaker history 59, no. 2 (Autumn 1970):  84 (81-97), was fond of the tailored suit, would bestow one upon him.  (No suit, or so the story goes, was ever forthcoming.)
