On page 183 of his book Cubic Forms, in the bibliographical remarks to the section on the twenty-seven lines, Manin quotes Henderson's historical summary:

> Indeed Sylvester once remarked, in his characteristical florid style:
> "Surely with as good reason as had Archimedes to have the cylinder,
> cone, and sphere engraved on his tombstone might our distinguished
> countrymen leave testamentary directions for the cubic eikosiheptagram
> to be engraved on theirs."
> 
> If Cayley and Salmon had wished to follow Sylvester's advice and to
> insert a clause in their wills, directing that an eikosiheptagram be
> engraved upon their monuments, they would have had no certainty of the
> correct fulfilment of their directions until the year 1869, when
> Christian Wiener made a model of a cubic surface showing twenty-seven
> real lines lying upon it. This achievement of Wiener, Sylvester once
> remarked, is one of the discoveries "which must for ever make 1869
> stand out in the Annals of Science."
> 
> Klein exhibited a complete set of models of cubic surfaces at the
> World's Exposition in Chicago in 1894, including Clebsch's symmetrical
> model of the diagonal surface and Klein's model of the cubic surface
> having four real conical points. Models of the typical cases of all
> the principal forms of cubic surfaces have been constructed by
> Rodenberg for Brill's collections; and these plaster models may now be
> purchased.

Manin concludes: "Henderson's book appeared in 1911. Sylvester's eloquence and the plaster models disappeared together with the Victorian era... "
