soon applied to warfare, and by the time of the mid 14th century there were many types of rocket launchers available. Fishing reel: In literary records, the earliest evidence of the fishing reel comes from a 4th-century AD work entitled Lives of Famous Immortals. The earliest known depiction of a fishing reel comes from a Southern Song (1127–1279) painting done in 1195 by Song dynasty painter Ma Yuan (c. 1160–1225) called "Angler on a Wintry Lake," showing a man sitting on a small sampan boat while casting out his fishing line. Another fishing reel was featured in a painting by the Yuan dynasty painter Wu Zhen (1280–1354). The book Tianzhu lingqian (Holy Lections from Indian Sources), printed between 1208 and 1224, features two different woodblock print illustrations of fishing reels being used. An Armenian parchment Gospel of the 13th century shows a reel (though not as clearly depicted as the Chinese ones). The Sancai Tuhui, a Chinese encyclopedia published in 1609, features the next known picture of a fishing reel and vividly shows the windlass pulley of the device. These five pictures mentioned are the only ones which feature fishing reels before the year 1651 (when the first English illustration was made); after that year they became commonly depicted in world art. Flamethrower, double piston and gunpowder-activated: Although the single piston flamethrower was first developed in the Byzantine Empire during the 7th century, the 10th-century Chinese flamethrower, or Pen Huo Qi, boasted a continuous stream of flame by employing double piston syringes (which had been known since the Han Dynasty) spouting Greek fire which had been imported from China's maritime trade contacts in the Middle East. It was first used in battle 932 during the Five Dynasties and Ten Kingdoms period (907–960), and the earliest illustration is found in the early Song Dynasty military manuscript Wujing Zongyao of 1044, which also described the device in full. Unlike the Greek model which employed a furnace, the Pen Huo Qi was ignited by an incendiary gunpowder fuse. Flare: The earliest recorded use of gunpowder for signalling purposes was the 'signal bomb' used by the Song Dynasty Chinese as the Mongol-led Yuan Dynasty besieged Yangzhou in 1276. These soft-shelled bombs, timed to explode in mid-air, were used to send messages to a detachment of troops far in the distance. Another mention of the signal bomb appears in a text dating from 1293 requesting
