Answer to Question 1

Radar studies of Venus finally determined that Venus' rotation rate is 243 days, retrograde. Studies of its entire surface from Earth, using radar, is complicated by the fact that almost the same face of Venus appears pointed towards Earth when the two planets are closest.

This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
