According to
wikipedia, "The
dove appears in many funerary inscriptions in the
Roman catacombs, sometimes accompanied by the words in pace (Latin for "in
peace"). [...] In another there is a shallow relief
sculpture showing a
dove with a branch flying to a figure marked in Greek ΕΙΡΗΝΗ (
Eirene, or
Peace)."
"The Carthaginian Tertullian (c.160 – c.220) compared Noah's
dove, who "announced to the world the assaugement of divine wrath, when she
had been sent out of the ark and returned with the olive branch" with the Holy Spirit in the form of a
dove that descends in baptism, "bringing us the
peace of God, sent out from the heavens".[30] In the fourth century, St. Jerome's Latin Bible, possibly reflecting this
Christian comparison between the
peace brought by baptism and the ending of the Flood, rendered the Hebrew Bible's "olive leaf" in Noah as "olive branch" (ramum olivae). By the fifth century, St Augustine of
Hippo confirmed the
Christian reading of the pagan olive branch into Noah,
writing that, "perpetual
peace is indicated by the olive branch (oleae ramusculo) that the
dove brought with it when it returned to the ark."
Wikipedia then gives a few examples: "In the late 15th century, a
dove with an olive branch was used on the seal of Dieci di Balia, the Florentine
committee known as The Ten of
Liberty and
Peace, whose secretary was Machiavelli; it bore the motto, "
Pax et Defencio
Libertatis" (
Peace and the Defence of
Liberty) --- "In 18th century America, a £2 note of
North Carolina (1771) depicted the
dove and olive with a motto meaning: "
Peace restored". Georgia's $40 note of 1778 portrayed the
dove and olive and a hand holding a dagger, with a motto meaning "Either war or
peace, prepared for both."; In the "Early 19th century the Society for the Promotion of Permanent and Universal
Peace, also known as The London
Peace Society, formed on Quaker initiative in 1816, used the symbol of a
dove and olive branch.", and this all before Picasso.
Still the watch postdates Picasso, if not by long. So even if one were the ignore the above extracts from the
wikipedia, it could tie in to the Picassoan motive.
