Not fools this time. More properly fowls, this time from Chaucer. His poem about the birds forming a parliament to debate and choose their mates contains one of the first references to St Valentine's day as a day for love.
"For this was on seynt Volantynys day Whan euery bryd comyth there to chose his mate."
Chaucer held a court position and wrote the poem back in 1382 and dedicated it to King Richard II as a celebration of the Kings' engagement to Anne of Bohemia. In Plato's words,"At the touch of love, everyone becomes a poet."
