The Skylla group was among the most famous bronze sculptures installed in the hippodrome at Constantinople. This paper suggests that the Skylla was a feature of Constantinople at its re-foundation, but perhaps originally stood facing the Bosphorus. In around AD 400 it was moved to the hippodrome where it stood until its destruction in 1204, and where it may for some time have served as a fountain.

An isolated police officer executing an arrest can be placed in a dangerous situation should the subject become non-compliant. Further research is needed to ascertain the position that a subject can be placed in that takes the longest time to rise from the ground. Twenty-four college-aged participants (15 men, 9 women) were recruited for this study. Four prone positions were examined in one session: hands hidden under the chest (PHC); arms perpendicular to the torso and palms of the hand facing up (PPU); arms perpendicular to the torso, palms of the hand facing up, with ankles crossed on the ground (PPUAC); and arms perpendicular to the torso, palms of the hand facing up, with ankles crossed but elevated toward the lower back (PACKB). The order of these positions was randomized amongst participants. Participants were instructed to rise to an athletic position from each position as quickly as possible, with the movements recorded by a video camera. Times were calculated via a frame-by-frame analysis using motion analysis soft - ware from movement initiation until participants were standing. A 2 (sex) x 4 (position) repeated measures ANOVA with Bonferroni post hoc calculated between-position differences. There was a significant ANOVA for position (p = 0.003) but not sex (p = 0.415). The PACKB position was significantly slower than the PHC and PPUAC positions (p ≤ 0.045) and had the slowest movement time to stand (~2.019 s). As reaction time could influence an officer's safety, the PACKB position required the most time for a subject to stand and potentially engage an officer.
