These are indeed little more than
conjectures. And I must add that in Professor Owen's opinion there is no
reasonable doubt that the Aepyornis was a bird allied to the Ostriches.
We gave, in the first edition of this work, a drawing of the great
Aepyornis egg in the British Museum of its true size, as the nearest
approach we could make to an illustration of the Rukh from nature. The
actual contents of this egg will be about 2.35 gallons, which may be
compared with Fra Mauro's anfora! Except in this matter of size, his
story of the ship and the egg may be true.
A passage from Temple's Travels in Peru has been quoted as exhibiting
exaggeration in the description of the condor surpassing anything that can
be laid to Polo's charge here; but that is, in fact, only somewhat heavy
banter directed against our traveller's own narrative. (See Travels in
Various Parts of Peru, 1830, II. 414-417.)
Recently fossil bones have been found in New Zealand, which seem to bring
us a step nearer to the realization of the Rukh.
