Definition of "glyde"

XX He so disseized[*] of his gryping grosse, The knight his thrillant speare again assayd In his bras-plated body to embosse, And three mens strength unto the stroke he layd; 175 Wherewith the stiffe beame quaked, as affrayd, And glauncing from his scaly necke, did glyde Close under his left wing, then broad displayd: The percing steele there wrought a wound full wyde, That with the uncouth smart the Monster lowdly cryde. 180 XXI He cryde, as raging seas are wont to rore, When wintry storme his wrathfull wreck does threat The roaring billowes beat the ragged shore, As they the earth would shoulder from her seat, And greedy gulfe does gape,[*] as he would eat 185 His neighbour element in his revenge: Then gin the blustring brethren[*] boldly threat To move the world from off his steadfast henge, And boystrous battell make, each other to avenge.
