` Which ? The stone one with the line from Xenophon ? ' said Puck , in quite a new voice . ` No ! What do I know of Xenophon ? That was Pertinax -- after he had shot his first mountain-hare with an arrow -- by chance ! Mine I made of round pebbles , in memory of my first bear . It took me one happy day to build . ' Parnesius faced the children quickly . ` And that was how we lived on the Wall for two years -- a little scuffling with the Picts , and a great deal of hunting with old Allo in the Pict country . He called us his children sometimes , and we were fond of him and his barbarians , though we never let them paint us Pict fashion . The marks endure till you die . ' ` How 's it done ? ' said Dan . ` Anything like tattooing ? ' ` They prick the skin till the blood runs , and rub in coloured juices . Allo was painted blue , green , and red from his forehead to his ankles . He said it was part of his religion . He told us about his religion -LRB- Pertinax was always interested in such things -RRB- , and as we came to know him well , he told us what was happening in Britain behind the Wall . Many things took place behind us in those days .
And by the Light of the Sun , ' said XXXXX , earnestly , ` there was not much that those little people did not know !
