of the tomb are visible in the walls. From Mausolus, we have the word ‘mausoleum’, meaning an ornate tomb.
5. The Statue of Zeus at Olympia is also lost to the modern world. Only images on coins and descriptions survive to tell us why the statue was considered so astonishing in the fifth century BC.
Olympia was the site of the ancient Olympic games – giving us the word. The site was sacred to Zeus, and Phidias of Athens was commissioned to carve the statue. The statue was of wood layered in gold for the cloth and ivory sheets for the flesh. In his right hand stood the winged figure of the goddess Victory (Nike), made of ivory and gold. In his left, he held a sceptre made of gold, with an eagle perched on the end.
The Roman emperor Caligula tried to transfer the statue to Rome in the first century AD, but the scaffolding collapsed under the weight and the attempt was abandoned. Later on, the statue was moved to Constantinople and remained there until it was destroyed by fire in the fifth century.
6. The Colossus of Rhodes in Greece is perhaps the most famous of the seven ancient wonders. It was a statue of Helios, over a hundred feet (30 m) high.
It did not actually stand across the harbour, but instead rested on a promontory, looking out over the Aegean Sea. The base was white marble and the statue was built slowly upwards, strengthened with iron and stone as the bronze pieces were added. It took twelve years and was finished around 280 BC, quickly becoming famous. An earthquake proved disastrous for the statue fifty years later. It broke at the knee and crashed to the earth to lie there for eight hundred years before invading Arabs sold it.
7. The Pharos Lighthouse at Alexandria was built by the architect Sostratus of Cnidus for the Greco-Egyptian king Ptolemy Philadelphus (285–247 BC).
Ptolemy’s ancestor had been one of Alexander the Great’s generals. His most famous descendant is Cleopatra who was the first of her Greek line actually to speak Egyptian. When Julius Caesar arrived in Alexandria, he would have passed by the great lighthouse on Pharos island. Its light was said to be visible for 35 miles (55 km) out to sea. Its exact height is unknown, but to have shed visible light to that distance, it must have been between 400 and 600 feet high (121–182 m).
It was so famous that, even today, the word for lighthouse in Spanish and Italian is ‘faro’. French also uses the same root, with ‘phare’.
As you can see, even the greatest wonders can be lost or broken by the passage of millennia. Perhaps the true wonder is the fact that we build them, reaching always for something greater than ourselves.
The Five Knots Every Boy Should Know
BEING ABLE TO TIE KNOTS in rope is extremely useful. It is amazing how many people only know a reef and a granny knot. Rather than naming hundreds, we’ve narrowed it down to five extremely useful examples.
However, they take endless practice. I learned a bowline on a sailing ship in the Pacific. For three weeks, I used an old bit of rope on every watch, night and day. On my return to England, I attempted to demonstrate the knot – and found it had vanished from memory. To be fair, it didn’t take long to recall, but knots should be practised every now and then, so they will be there when you need them. There are hundreds of good books available, including expert levels of splicing and decorative knots. These are the standard basics – useful to all.
1. THE REEF KNOT
This knot is used to reef sails – that is, to reduce the amount of sail area when the wind is getting stronger. If you look at a dinghy sail, you’ll notice cords hanging from the material. As the sail is folded on the boom, the cords are tied together using reef knots. It is symmetrical and pleasing to the eye.
The rule to remember is: left over right, right over left.
2. THE FIGURE OF EIGHT
This is a “stopper’ – it goes at the end of a rope and prevents the rope passing through a hole. A double figure of eight is sometimes used to give the rope end weight for throwing. It’s called a figure of eight because it looks like the number eight.
3. THE BOWLINE (PRONOUNCED BOW-LIN)
This is a fantastically useful, solid knot. It is used whenever a loop on the end of a rope is needed – for a post, a ring, or anything else really.
1 Make a loop towards yourself, leaving enough free at the end to go around your post, tree or similar object
2 Now – imagine the loop is a rabbit hole and the tip is the rabbit. The other end of the rope is the tree. Feed the tip up through the hole – the rabbit coming up.
3 Pass the rabbit round the back of the tree.
4 Pass the rabbit back down the hole – back into the original loop.
5 Pull tight carefully.
NOTE: You can make a simple lasso by making a bowline and passing the other end of the rope through the loop. The bowline does not slip, so is useful for making a loop to lower someone, or to throw to a drowning person.
4. SHEET BEND
This is a useful knot for joining two ropes together. Reef knots fail completely when joining ropes of different diameters – but a sheet bend works very well.
5. A CLOVE HITCH – FOR HITCHING TWO THINGS TOGETHER VERY QUICKLY
This is a short-term knot – the sort of thing you see used by cowboys in westerns to hitch their horses. Its main benefit is that it’s very fast to make. Basically, it’s wrapping a rope around a post and tucking an end into a loop. Practise this one over and over until you can do it quickly.
These five knots will be useful in a huge variety of situations, from building a treehouse to camping, to sailing, to tying up your horse outside a saloon. They will not come easily. They take practice and patience. Knowing this will not impress girls, but it could save your life – or your horse.
