In return Gabriel assures Uriel no creature of any kind passed through them, and that if an evil spirit overleapt the earthly bounds he will be discovered before morning, no matter what shape he has assumed.

While Uriel returns to his post in the sun, gray twilight steals over the earth, and Michael, having appointed bands of angels to circle Paradise in opposite directions, despatches two of his lieutenants to search for the hidden foe.
Our first parents, after uniting in prayer, are about to retire, when Eve, who derives all her information from Adam, asks why the stars shine at night, when they are asleep and cannot enjoy them?
In reply Adam states that the stars gem the sky to prevent darkness from resuming its sway, and assures his wife that while they sleep angels mount guard, for he has often heard their voices at midnight.

Then the pair enter the bower selected for their abode by the sovereign planter, where the loveliest flowers bloom in profusion, and where no bird, beast, insect, or worm dares venture.
In the course of their search, the angels Ithuriel and Zephon reach this place in time to behold a toad crouching by the ear of Eve, trying by devilish arts to reach the organs of her fancy.

Touched by Ithuriel's spear,--which has the power of compelling all substances to assume their real form,--this vile creature instantly assumes a demon shape.

On recognizing a fiend, Ithuriel demands how he escaped and why he is here.
