So far, so good. There is in fact one other requirement: Patience. ($1 = 0.8432 euros) We have just measured one, it fits the required criteria in length and diameter. It was made by architect Viollet-le-Duc in 1859.
Patience is valued at one dollar.
( z0 value :ARG1 ( z1 patient ) :ARG2 ( z2 monetary-quantity :quant 1 :unit ( z3 dollar ) ) )
(z0 / value-01
    :ARG1 (z1 / patient-01)
    :ARG2 (z2 / monetary-quantity
              :quant 1
              :unit (z3 / dollar)))
Patience is valued at one dollar .
