255 From a letter to Mrs Eileen Elgar
[Some notes on a poem in The Adventures of Tom Bombadil.]
5 March 1964
The poem on Fastitocalon is not like Cat and Oliphaunt my own invention entirely but a reduced and rewritten form, to suit hobbit fancy, of an item in old 'bestiaries'. I think it was remarkable that you perceived the Greekness of the name through its corruptions. This I took in fact from a fragment of an Anglo-Saxon bestiary that has survived, thinking that it sounded comic and absurd enough to serve as a hobbit alteration of something more learned and elvish – according to [a] system whereby as English replaces the Shire-speech so Latin and Greek replace the High-elven tongue in names. The learned name in this case seems to have been Aspido-chelōne 'turtle with a round shield (of hide)'. Of that astitocalon is a corruption no worse than many of the time; but I am afraid the F was put on by the versifier simply to make the name alliterate, as was compulsory for poets in his day, with the other words in his line. Shocking, or charming freedom, according to taste.
He says: þam is noma cenned/fyrnstreama geflotan Fastitocalon, 'to him is a name appointed, to the floater in the ancient tides, Fastitocalon'. The notion of the treacherous island that is really a monster seems to derive from the East: the marine turtles enlarged by myth-making fancy; and I left it at that. But in Europe the monster becomes mixed up with whales, and already in the Anglo-Saxon version he is given whale characteristics, such as feeding by trawling with an open mouth. In moralized bestiaries he is, of course, an allegory of the Devil, and is so used by Milton.
