The Objections To The Alleged Age Of These Instruments Were Entirely Based On An Inspection Of Photographs.

The opinion was given very strongly that no instrument of the kind, so perfect in theory and in execution, could have been even imagined in those days, and that nothing of such scientific quality could have been made except by the Jesuits.

In fact it was asserted or implied that these instruments must have been made about the year 1700, and were therefore not earlier in age than those which stand on the terraced roof of the Observatory, and are well known to most of us from the representation in Duhalde and in many popular works.

The only authority that I could lay hand on was Lecomte, and what he says was not conclusive. I extract the most pertinent passages:

"It was on the terrace of the tower that the Chinese astronomers had set their instruments, and though few in number they occupied the whole area. But Father Verbiest, the Director of the Observatory, considering them useless for astronomical observation, persuaded the Emperor to let them be removed, to make way for several instruments of his own construction. The instruments set aside by the European astronomers are still in a hall adjoining the tower, buried in dust and oblivion; and we saw them only through a grated window. They appeared to us to be very large and well cast, in form approaching our astronomical circles; that is all that we could make out.
