This ingenious inspiration actually came from the bicycle rain canopy of later generations,
This contraption ensured maximum safety from the skies,
Although there was no such thing as an air raid in this age, to achieve certain effects, arrows were always shot upwards from beneath the city walls,
As such, they would fall in parabolic trajectories,
And thus, a great number of arrows would only fall back towards the sky,
Meaning that the arrows dropping from above would be even more powerful,
And therefore, this canopy-like wooden shield provided significant protection.
Moreover, this device was cleverly designed, with wheels on the bottom that could easily move in any direction,
This also marked the first appearance of a primitive omnidirectional wheel,
