Spears in Qing art. Source:
This (and the rest of the volumes) is the source.
(a) 18th century, Luoluo people in Yunnan. Spears about 8' long, heads might be single-edged. Steel/iron butt spikes.
(b) 1793, war against Gurkhas. Spears are about 10' long, heads are long, maybe 10" blades, parallel sides. Red tassels at base of head, no butt spikes.
(c) 1829, suppression of rebellion in Xinjiang. Spears as above.
(d) Some enlarged details of some paintings are shown, but the sources are not given. One series, which appear to be about the defeat of the Zunghars, has spears of about 10', red tassels, diamond-shaped heads. In other details, spears are shown with no tassels, a sleeve about the blade end of the haft, and butt spikes.
