I know this may not be relevant to TMA but I expect Obelix inspired many a person into wondering what was it with those prehistoric stones in Brittany. As someone who had to buy religiously every new Asterik book/comic for her son back in time (and they were a great deal more interesting than some of the archaeology books I've read)......
Happy Birthday Asterix and Getafix the druid, and chucking menhir Obelix.
p.s. Moth and Jane's recent visit to Brittany is certainly inspirational and representational of the enormous stones Obelix tossed with such careless ease.
