If you are at all serious about Welsh mythology, you will want Rachel Bromwich’s Triodd Ynys Prydein. Bromwich has a super introduction, all the triads, in English and Welsh, and extensive notes on names. Her notes alone are worth the money.

The Welsh name for Snowdon, Yr Wyddfa, means grave and is pronounced like "er with-va".The story goes in a legend that the giant Rhita Gawr, the king of Wales, was buried under a cairn of stones on the summit of the mountain, following a battle with King Arthur.It is said that the giant defeated 30 kings of Britain, taking their beards to create a cloak of the beards, reaching from his shoulder to the floor.

The Mabinogion, translated by Sioned DaviesIn You Goddess! we use “supernatural female” as a definition of goddess and this allows us to include the story of Blodeuwedd, who was created out of flowers by a wizard as a wife for his friend, but who kicks over the traces and finds her own partner. Bloeuwedd appears in this medieval collection of Welsh stories. The first English translation was published in the 19th century by the linguist, go-getter and driver of the Welsh renaissance, Lady Charlotte Guest. This 2007 translation by Sioned Davies is a fantastic contemporary version. In the past Blodeuwedd has been taken as a cautionary tale about adultery, but to modern readers she appears as a floral rebel breaking free from male control. Sadly things don’t end well for her and her metamorphosis from vegetable to human ends with her wizard enemy turning her into an owl. She lives on as the inspiration for Alan Garner’s The Owl Service.
