Somewhat Truth in Television; many pagan religions include a sickle-shaped work knife called a boline as part of the ritual tools, though it's not generally considered a weapon. The association of sickles with druids and druidic ceremonies in particular stems from the Roman historian Pliny the Elder's description of the ritual of oak and mistletoe, where druids would use golden sickles to harvest mistletoe as part of an elaborate religious ceremony.
I hereby consecrate these examples in the names of the Lord and Lady:
- Asterix: The page image features the druid Getafix, who uses a golden sickle to gather potion ingredients. This is apparently especially important for the gathering of mistletoe, the only non-secret ingredient of the druid's magic potion: mistletoe must be harvested with a golden sickle, or it loses all its magical powers. Getafix's sickle breaks in Asterix and the Golden Sickle, forcing Asterix and Obelix to go on a quest to find a new one in time for the upcoming gathering of druids, since Getafix couldn't bear the shame of being the only sickle-less druid present.
- In The Mists of Avalon, the priestesses receive Druidic Sickles as part of their initiation.
- Dungeons & Dragons:
- In AD&D, Druids use mistletoe as a component of casting their spells. They have to cut a full year's supply on Midsummer's Eve with a sickle made of silver or gold.
- In 3rd Edition, the Druid class has a very short list of weapon proficiencies, including the sickle alongside simple weapons like knives, staves and smaller spears. The only martial weapon with which they are proficient is the scimitar, which is vaguely sickle-like in shape.
- Lini, the iconic Druid from Pathfinder, wields a sickle. Particularly notable in light of her serving as the game's archetypal druid adventurer.
- Dawn of the Dragons: In Clash of the Dragons, the Druid's Sickle is a special weapon that can only be used by, unsurprisingly, druids. The art for the Druid class also shows the character in question holding a sickle in his hand.
"My sickle gathers herbs, the fruits of the soil. And it slits the throats of animals destined for my cooking pot. Both life and death live upon its edge."
- The Lone Druid of Dota 2 attacks by throwing sickles at his enemies.
- World of Warcraft: The iconic druidic artifact is the Scythe of Elune, a scythe made from the staff of the goddess Elune, the patron deity of the druids, and a fang of the wolf god Goldrinn, another deity worshipped by some druidic orders. It is also the artifact that lead to the creation of the worgen, a species strongly associated with druidism.
