I am foreborn of spud runts who fled the famines of Ireland in the 1830s, not a man or woman among them more than five foot two, leaving behind a life of beggarment and setting sail for what since Malory were called the Happy Isles to take up unadvertised positions as servants in the underclass of Newfoundland.

Having worked off their indenture, they who had been sea-fearing farmers became seafaring fishermen and learned some truck-augmenting trade or craft that they practised during the part of the year or day when they could not fish.

Their names.

In reverse order: Johnston. Johnson. Jonson. Jenson...MacKeown. "Mac" in Gaelic meaning "son" and Keown "John."

My father grew up in a house that was blessed with water from an iceberg. A picture of that iceberg hung on the walls in the front rooms of the many houses I grew up in. It was a blown-up photograph that yellowed gradually with age until we could barely make it out. My grandmother, Nan Johnston, said the proper name for the iceberg was Our Lady of the Fjords, but we called it the Virgin Berg.

In 1905, on June 24, the feast day of St. John the Baptist and the day in 1497 of John Cabot's landfall at Cape Bonavista and "discovery" of Newfoundland, an iceberg hundreds of feet high and bearing an undeniable likeness to the Blessed Virgin Mary appeared off St. John's harbour. As word of the apparition spread, thousands of people flocked to Signal Hill to get a glimpse of it. An ever-growing flotilla of fishing boats escorted it along the southern shore as it passed Petty Harbour, Bay Bulls, Tors Cove, Ferryland, where my father's grandparents and his father, Charlie, who was twelve, saw it from a rise of land known as the Gaze.

At first the islands blocked their view and all they could see was the profile of the Virgin. But when it cleared Bois Island, they saw the iceberg whole. It resembled Mary in everything but colour. Mary's colours were blue and white, but the Virgin Berg was uniformly white, a startling white in the sunlight against the blue-green backdrop of the sea. Mary's cowl and shawl and robes were all one colour, the same colour as her face and hands, each feature distinguishable by shape alone. Charlie imagined that, under the water, was the marble pedestal, with its network of veins and cracks. Mary rode without one on the water and there did not extend outwards from her base the usual lighter shade of sea-green sunken ice.

The ice was enfolded like layers of garment that bunched about her feet. Long drapings of ice hung from her arms, which were crossed below her neck, and her head was tilted down as in statues to meet in love and modesty the gaze of supplicants below.

Charlie's mother fell to her knees, and then his father fell to his. Though he wanted to run up the hill to get a better look at the Virgin as some friends of his were doing, his parents made him kneel beside them. His mother reached up and, putting her hand on his shoulder, pulled him down. A convoy of full-masted schooners trailed out behind the iceberg like the tail of some massive kite. It was surrounded at the base by smaller vessels, fishing boats, traps, skiffs, punts. His mother said the Hail Mary over and over and blessed herself repeatedly, while his father stared as though witnessing some end-of-the-world-heralding event, some sight foretold by prophets in the last book of the Bible. Charlie was terrified by the look on his father's face and had to fight back the urge to cry. Everywhere, at staggered heights on the Gaze, people knelt, some side-on to keep their balance, others to avert their eyes, as if to look for too long on such a sight would be a sacrilege.

A man none of them knew climbed the hill frantically, lugging his camera, which he assembled with shaking hands, trying to balance the tripod, propping up one leg of it with stones. He crouched under his blanket and held above his head a periscope-like box which, with a flash and a puff of foul-smelling yellow smoke, exploded, the mechanism confounded by the Virgin, Charlie thought, until days later when he saw the picture in the Daily News. Even then it seemed to him that the Virgin must have lent the man's machine the power to re-create in black and white her image on the paper, the same way she had willed the elements to fashion her image out of ice.

He had seen photographs before but had never watched as one was taken. She was the first object he had seen both in real life and in photographs. For the rest of his life, whenever he saw a photograph, he thought of her and the man he had been so surprised to see emerge unharmed from beneath his blanket.

How relieved he was when the Virgin Berg and her attending fleet sailed out of sight and his parents and the other grownups stood up and blessed themselves. Soon the miracle became mere talk, less and less miraculous the more they tried to describe what they had seen, as if, now that it was out of sight, they doubted that its shape had been quite as perfect as it seemed when it was looming there in front of them.

They heard later of things they could not see from shore, of the water that ran in rivers from the Virgin, from her head and from her shoulders, and that spouted from wound-like punctures in her body, cascading down upon the boats below, onto the fishermen and into the barrels and buckets they manoeuvred into place as best they could. Some fishermen stood, eyes closed and mouths wide open, beneath the little waterfalls, gulping and gagging on the ice-cold water, their hats removed, their hair and clothing drenched, hands uplifted.
