When, in A Midsummer Night’s Dream, Oberon sends Puck to fetch the magic flower, he gives him a deadline:

Fetch me this herb; and be thou here again
Ere the leviathan can swim a league.

I don’t know how fast the Leviathan could swim, so let’s talk about whales.

According to the New York State Department of Environmental Conservation, the fastest whales can reach speeds of up to 40 mph. If you Google “40 miles per hour in leagues per minute” it will convert the speed for you; it’s about 0.193 leagues per minute. So it would take about 5.18 minutes for the world’s fastest whale to swim a league, and I doubt it would take the Leviathan any longer.

Puck’s not ready to promise that. He responds:

I’ll put a girdle round about the earth
In forty minutes.

He’s going to need more time than Oberon asked, but to be fair, he’s going to take the long route.

Is it possible to do a complete circumnavigation of the Earth in 40 minutes? Puck’s got some powerful magic behind him, but that seems like a pretty fast journey. The Earth is almost 25,000 miles around. This claim needs a Shakespeare Follow-Up.

The 16th century voyages of Magellan and Drake would have been known to Shakespeare when he wrote the play. But these expeditions took years, and Puck didn’t have that kind of time. Over the next few centuries, many would make the trip, but it was always measured in years.

In 1873, Jules Verne wrote a fantasy novel called Around the World in Eighty Days, which documents a fictional attempt by Phileas Fogg to achieve the title journey in order to win a bet. Fogg travels by railroad and steamship, which gives him an advantage over his purely nautical predecessors. While they have to navigate around landmasses, he gets to travel a more direct route. Also, he’s a fictional character, but so is Puck. In the real world, the current record for sailing around the world belongs to French yachtsman Loïck Peyron. He ended his journey in January 2012 after 45 days, 13 hours, 42 minutes and 53 seconds. His prize? The Jules Verne Trophy.

Impressive as that is, Puck’s not going to make his deadline in a sailboat. What about hitching a ride on the Moon, a naturally orbiting satellite with close ties to the play? Well, as you might guess, the Moon takes about a month (29.5 days) to show its phase to the Earth. That’s faster than Peyron, but not fast enough for our time-pressed friend.

Shakespeare’s England wouldn’t have known any more of modern flight than Puck’s Athens, but we need to cut down our time. In 2010, Riccardo Mortara, Gabriel Mortara, and Flavien Guderzo set the record for a jet airplaine circumnavigation in 57 hours and 54 minutes, beating the Moon by a significant margin but still falling short of our goal. Being a fairy, Puck might have some connections to Santa Claus, who reportedly can make the worldwide journey in a single night. But to really pick up some speed, Puck should look into a spacecraft.

In 1961, Yuri Gagarin completed the first orbit of the Earth in 108 minutes. Now, we’re talking! There have been numerous orbits since that historic trip. I haven’t been able to find the fastest orbit, which is strange since you’d think that would be a big deal. I did find someone on a space message board who claims that Apollo 17 holds the current record at 87.82 minutes. I haven’t been able to find a source confirming that, but I haven’t been able to find a source contradicting it either. So given our current state of technology, the fastest estimate of a non-magical human circumnavigation given by even Internet hearsay is more than twice as long as Puck’s 40-minute promise.

So what happens in the play? After Puck leaves, Demetrius and Helena enter, have a scene together, and exit. Then, Puck returns with the flower. The length of the scene can certainly vary between productions, so to get a reasonable estimate, I consulted the relevant scene in two audio recordings from my collection. In the Arkangel version, Puck departs at 11:40 and returns at 15:40. He is away exactly 4 minutes. In the Naxos version, Puck is even faster. He’s gone from 9:11 to 12:54, for a total of 3 minutes and 43 seconds. We don’t know if he fulfills his ambition to put a girdle round about the earth, but it seems that he does indeed return ere the leviathan can swim a league.

Even a freewheeling sprite like Puck understands the importance of working on the boss’s timetable.
