Milton never uses the word picnic or any synonym but knows the concept and uses it freely for satiating Adam and Eve in Paradise before the Fall in Paradise Lost. Because they had no means of cooking, Milton supposes that Adam and Eve were inadvertent Vegans picnicking at every meal with available vegetation and that they ate reclining on “damskt grass . . . under a tuft of shade.” The fatal apple, a russet fruit, according to Milton, came later.  As with some picnics, the picnickers become amorous, and after their meal, the primal couple couple-up (pun intended):

. . .   by a fresh fountain side
T
hey sat them down, and after no more toil
f thir sweet Gardning labour then suffic’d
To recommend coole Zephyr, and make ease
More easie, wholsom thirst and appitite
Moregratefu, to thir Supper Fruits they fell, Yeilded them, side-long as they sat recline
On th soft downie Bank damasket with flours:
T
he savourie pulp they chew, and the rinde
S
till as they thirted scoop the brimming stream;
N
or gentle purpose, nor endearing smiles
W
anted, no youthful dalliance as beseems
F
air couple, linkt in happy nuptial League,
Alone as they.  (Book  IV)

After the Fall, life is not a picnic. The unhappy pair wanders out of Paradise through the Eastern Gate into the world.
