The Pillars of the Earth - Ken Follett [240]
Aliena and Richard were given a shovel each and told to dig foundations. The ground was damp but the sun was out and it would soon dry the surface. Aliena began to dig energetically. Even with fifty people working, it took a long time to make the holes noticeably deeper. Richard rested on his shovel rather frequently. One time Aliena said: “If you ever want to be a knight, dig!” But it made no difference.
She was thinner and stronger than she had been a year ago, thanks to tramping the roads and lifting heavy loads of raw wool, but now she found that digging could still make her back ache. She was grateful when Prior Philip rang a bell and declared a break. Monks brought hot bread from the kitchen and served weak beer. The sun was growing stronger, and some of the men stripped to the waist.
While they were resting, a group of strangers came through the gate. Aliena looked at them hopefully. There were just a handful of them, but perhaps they were the forerunners of a large crowd. They came over to the table where the bread and beer was being handed out, and Prior Philip welcomed them.
“Where are you from?” he asked as they gulped gratefully at their pots of beer.
“From Horsted,” one of them replied, wiping his mouth on his sleeve. That was promising: Horsted was a village of two or three hundred people a few miles west of Kingsbridge. They might hope for another hundred volunteers from there, with luck.
“And how many of you are coming, in all?” Philip asked. The man looked surprised at the question. “Just us four,” he replied.
During the next hour people trickled through the priory gate until, by midmorning, there were seventy or eighty volunteers at work, including the villagers. Then the flow stopped altogether.
It was not enough.
Philip stood at the east end, watching Tom build a wall. He had already constructed the bases of two buttresses up to the level of the third course of stones, and now he was building the wall between. It would probably never be finished, Philip thought despondently.
The first thing Tom did, when the laborers brought him a stone, was to take out an iron instrument shaped like the letter L and use it to check that the edges of the stone were square. Then he would shovel a layer of mortar on to the wall, furrow the mortar with the point of his trowel, put the new stone on, and scrape off the surplus mortar. In placing the stone he was guided by a taut string which was stretched between the two buttresses.
Philip noticed that the stone was almost as smooth on the top and bottom, where the mortar was, as on the side that would show. This surprised him, and he asked Tom the reason. “A stone must never touch the ones above or below,” Tom replied. “That’s what the mortar’s for.”
“Why must they not touch?”
“It causes cracks.” Tom stood upright to explain. “If you tread on a slate roof, your foot will go through it; but if you put a plank across the roof, you can walk on it without damaging the slates. The plank spreads the weight, and that’s what mortar does.”
Philip had never thought of that. Building was an intriguing business, especially with someone like Tom, who was able to explain what he was doing.
The roughest face of the stone was the back. Surely, Philip thought, that face would be visible from inside the church? Then he recalled that Tom was in fact building a double-skinned wall with a cavity between, so that the back of each stone would be hidden.
When Tom had laid the stone on the bed of mortar, he picked up his level. This was an iron triangle with a leather thong attached to its apex and
