abduxere retro longe capita ardua ab ictu immiscentque manus manibus pugnamque lacessunt, ille pedum melior motu fretusque iuventa, hic membris et mole valens; sed tarda trementi genua labant, vastos quatit aeger anhelitus artus.
Raising their heads high and drawing them far back from blows, they spar, hand with hand, and provoke the fray, the one nimbler of foot and confident in his youth, the other mighty in massive limbs; yet his slow knees totter and tremble and a painful gasping shakes his huge frame.
