'The ground hereabouts appears solid, but beneath it lies a pool filled with water. For this reason the ground gives way beneath the weight of the stone and the walls cannot hold.'

'Liar!' shouted Joram. 'It is a trick to save his life!'

'The truth of what I say can be easily proven,' I replied calmly. 'Vortigern, send your men to dig a ditch and you will see I speak the truth.'

Pelleas, who had stood by me all this time, managed to look both relieved and worried by this turn of events. 'Are you certain, master?' he whispered, as Vortigern called for workmen to carry out my orders.

'I know what I am doing, Pelleas,' I told him. 'But watch, there is more to come.'

I pointed out to the workmen where to dig and they set about it at once. It took some time for the hole to reach the proper depth, and with each shovelblade full the druid's satisfaction increased. For it appeared there would be no water.

But when the hole reached man height, one of the workers with an iron pick swung down and struck a piece of rock. The rock broke and he pulled out his pick to swing again and all at once water began bubbling up into the hole. In the end, the men had to scramble out to keep from being drowned.

Vortigern's court looked on in wonder as the gushing water filled the hole to the very top.

'Well done, Myrddin!' cried Vortigern. He turned sharply to Joram and demanded, 'What do you have to say to that, traitor?'

Joram had nothing to say. He held his tongue and fumed darkly at me. His fellows, clustered around him, muttered oaths and incantations against me, but they had no power and their spells fell like spent arrows at their feet. I understood then how very low the art of the bard had fallen, and it saddened me.

Taliesin, forgive your weaker brothers if you can. Ignorance spreads to every quarter on the wind, and truth is spurned and reviled.

Vortigern asked me then to name my reward, and I answered, 'I will not take silver or gold from you, Vortigern.'

Take land then, friend,' he offered.

'Nor land,' I said. I wanted nothing from his hand. Indeed, how could I take from him a thing that was not his to give?

'Very well, let it be as you say. But I will have you share meat with me tonight. And,' his eyes gleamed wickedly, 'there will be an entertainment.'

I was given a tent in which to rest and refresh myself before supper. Pelleas and I retired and I slept, waking when a servant brought a basin for me to wash. Then we were led back to the hall and given seats at the high table next to Lord Vortigern. The druids were still there, still furious, their faces dark with rage and menace, but they were huddled next to the hearth and did not share Vortigern's table tonight.

'Welcome, friend Myrddin!' cried Vortigern when he saw me. The guest cup was pressed into my hand. 'Was Hael! Drink, friend! And fill your cup again!'

I drank and returned the cup. It was filled again, but I left it on the board and took my place beside the king. The meal was remarkable only for the quantity of food prepared. Vortigern and his retinue appeared to have endless appetites, but easily pleased palates. The fare was common – black bread, roasted meat – all cooked well enough, but ungarnished and unspiced.

Vortigern gave himself to his meal; I see him now, hunched over his plate, tearing meat from his knife with his teeth. Poor Vortigern, there was not a noble sinew in his body. How far he had overreached himself.

He did not speak during the meal, but when at last he wiped the grease from his lips with his sleeve, he turned to me. 'Now for a drink and some diversion, eh, Myrddin?'

Pelleas, who had served me through the meal so that he could remain by my side, did not like the sound of that. He gave me a warning look, but Vortigern had no mischief in mind for me.

The High King called for his chief bard and Joram shuffled forth warily. 'Do not think I have forgotten your treachery to me, druid,' said Vortigern, as the bard came to stand before him.

'If you would find treachery,' answered Joram sullenly, 'you have but to look no further than the one sitting at your right hand.'

'Enough of your slander!' the king snapped. 'I will hear no more from you.' He beckoned the captain of his bodyguard to him and declared before all the court, 'These men, who I entrusted with my life, have shown themselves false before me. They are worse than traitors. Draw your sword and kill them at once.' This was Vortigern all over – efficient, if ruthless, and eager to secure the friendship of powerful men who could help him. The soldier's steel came ringing from its sheath.

He hoped by this display to win me, for he turned to me and said, 'As these blind magicians were so eager for your blood, surely they will not mind my asking for theirs.'

There was nothing I could do for them; Vortigern was determined. But I wanted them to know, at last, who it was they had sought to destroy. 'If you please, Lord Vortigern, the reward you offered – I would claim it now.'

'By whatever god you worship, Myrddin, you shall have it. What do you propose?'

'A story,' I replied. 'Before they die, I would have them contemplate the power of a true bard.'

Vortigern had hoped for something more exotic, but he smiled graciously and ordered a harp to be brought to me. I took my place before the table and tuned the harp, as Vortigern's company gathered around me. I do not think that even then I knew precisely what I would say but, as I fingered the strings of the harp, searching for a melody, the words began forming on my tongue of their own accord and I knew that I had been led to this place and the words would be given in turn.

The harp nestled against my shoulder, I turned to Joram and said, 'As you show so little respect for the high bardic arts of old, I will tell you a true tale.' Lifting my voice to the hall, I said, 'Listen well, all of you.'

I gathered my cloak around me, closed my eyes and began to speak as one would speak to children. And this is the tale I told:

There was an eagle, and the father of eagles, who lived long, protecting his realm with beak and claw. One day a shrew came to Eagle and squatted beneath the oak where Eagle maintained his eyrie. And there he stayed until Eagle should speak to him.

'What do you want?' demanded Eagle. 'Tell me quickly, for I shall not suffer the like of you beneath my noble abode.'

'It is but a little thing,' replied Shrew. 'Only come down closer so that I may speak my matter plainly. For I grow dizzy shouting up at you like this.'

Eagle, being impatient to have an end to the matter, did as he was bade and flew down to meet Shrew. 'Well, here I am,' said Eagle. 'What do you want?'

'My voice is raw,' said Shrew, 'from all this shouting. Please come nearer.'

Eagle put his head near and, all at once, Shrew leapt upon his neck and bit it with his sharp teeth, so that Eagle was wounded grievously and died as his blood rushed out. Thereupon Shrew ran away so that no one ever saw him again.

When the other beasts and birds learned that Eagle had been wickedly killed, they were aggrieved and angry, for the exalted bird had been their king. They buried their lord and looked among themselves for a new king. 'Who can take Eagle's place?' they lamented. 'For none there is the like of our lord."

But the fox was crafty and cunning. Seeing his chance, up he jumped and said, 'Does not our lord leave heirs behind? Let his oldest son be our lord.'

'For a fox, you are a foolish one,' replied the otter. The young eagles are only nestlings. They cannot even fly.'

'But they will soon grow up. Meanwhile, let us elect someone to stand guard over them, until the eldest of the three has come of an age to take up the lordship of the forest.'

'Well said,' declared the ox. 'Who will do this thing which you suggest?'
