The Vertical Rope was an acrobatic act performed on a single vertical rope.
Similar to Spanish Webs that would later appear in Quidam, this act featured a
performance by the Adagio family - Nicolai Tchelnokov, Galina Karableva, and
their son Anton. Although the act could theoretically be used to replace any
missing number, it was generally used to replace the Boledaoras.
