赫尼文(Henwen)，含意是“老白”(Old White)，威尔士传说中的一只母猪，根据威尔士三题诗(Welsh Triads)记载，它生下了“凯茜·帕鲁格”(Cath Palug)，《亚瑟王传奇》中被描绘成与凯爵士(Sir Kay)或亚瑟王对抗的可怕之猫。在三题诗《马恩岛三大猪倌》中, 这只母猪由其中一科尔(Coll)-科尔福尔威(Collfrewy)之子，达尔威·达尔班(Dallwyr Dallben)的猪倌所饲养。在变体《赫杰斯特红皮书》(Red Book of Hergest)和《莱德尔齐白皮书》(Book of Rhydderch)文中添加了达尔威以他的名字命名一座峡谷的内容，该峡谷就位于康沃尔郡。母猪即将分娩，这预示着会给马恩岛(the Isle of Britain)带来灾祸。为此，它受到驱逐直止在康沃尔的彭林·阿斯丁(Penrhyn Awstin )坠海。但最终，该母猪在格温特郡伊斯柯艾德(Iscoed)的塔罗吉河口(Aber Tarogi)重现于大地 。

Henwen, meaning "Old White", is in Welsh legend a sow (female pig) which according to the Welsh Triads gave birth to Cath Palug, a monstrous cat depicted as combating with either Cai (Sir Kay) or King Arthur of Arthurian Legends. According to the triad "Three Powerful Swinherds of the Isle of Britain", the sow was kept by one Coll, son of Collfrewy, a pigkeeper for Dallwyr Dallben (also spelt Dallweir). The variant Red Book of Hergest (RBH) and White Book of Rhydderch (WBR) texts add that the Dallwyr held a valley named after him, the Glen of Dallwyr in Cornwall. The sow was ready to give birth, but this boded ill for the Isle of Britain, according to prophecy, so she was chased until she plunged into the sea at Penrhyn Awstin in Cornwall. The sow eventually re-emerges on land at Aber Tarogi in Gwent Is-coed (a subdivision of Gwent).
