Good find, TheRevealer. James Penton, in his "Apocalypse Delayed", referred to the WTS's dishonest use of this book as well. In the footnotes on page 372 he wrote:
"The society has, of course, pointed out something useful by noting that stauros does not necessarily mean 'cross' but simply a pale or timber. But nothing demonstrates so clearly how much their scholarship is affected by dogmatism than does this issue. There is a great deal of evidence from early church fathers such as Justin Martyr that Christians in his day believed that Christ was put to death on a cross. Roman writers such as Cicero state that Roman criminals were often executed on a cross, and modern archaeology supports the theory that Jews in Jesus' day were crucified on a cross.
"Finally, by showing but one illustration of Justus Lipsius' De cruce libri tres -- a picture of a man impaled on a crux simplex or upright pale -- on page 1578 of the New World Translation of the Holy Scriptures with References, Watch Tower scholars falsely leave the impression that Lipsius thought thay Jesus was put to death in that way. In fact, Lipsius gives 16 illustrations of impalement, 13 of which show stakes with some sort of cross member. Although there is no conclusive proof, there is evidence that Christ died on a cross."
