Petrarch's Sonnet 190 (compare with Wyatt, "Whoso List to Hunt")
A white doe on the green grass appeared to me, with two golden
horns, between two rivers, in the shade of a laurel, when the sun
was rising in an unripe season.
Her look was so sweet and proud that to follow her I left every
task, like the miser who as he seeks treasure sweetens his trouble
with delight.
"Let no one touch me," she bore written with diamonds and
topazes around her lovely neck. "It has pleased my Caesar to
make me free."
And the sun had already turned at midday; my eyes were tired
by looking but not sated, when I fell into the water, and she
disappeared.
