[17] The Bristol Mercury and Daily Post thought that "Strephon was effectively rendered by Mr. F. Federici, who not only acquitted himself very satisfactorily in the singing, but infused into the part a vein of quiet humour".
[18] However, The Era had a mixed reaction: "Mr. F. Federici, though a good actor, is a trifle too robust in style",[19] and the Liverpool Mercury wrote that "he is too conscious of the importance of the place he holds in the piece".
