In this video:
The ancient Romans were a people famed for their architectural prowess, something no better demonstrated than by their ability to build almost perfectly straight and incredibly durable roads spanning expansive distances. For example, in Britain alone, the Romans built well over 50,000 miles of roads with the longest ruler-straight stretch spanning over 50 miles. They did all of this in an era without modern surveying tools, construction equipment, or even very accurate maps of precisely where their destination was for many of the areas. So how did they do it?

@NutsinBrazil Because the English wouldn't have known what a lyre was. Also, 'lyre' sounds like the English world 'liar' which means 'one who lies', and the structure of the saying would have required them to use 'lyred' which would not have made sense. A fiddle is a name for a violin, but it is also a verb which means 'to touch or fidget in a nervous way', a description of what playing a violin would look like. Hence you can have the saying in English as it is structured with the verb implying the instrument being played, even if there weren't any violins in Nero's time.

In Portuguese we say that "Nero played the lyre while Rome burned". I don't know why the English version is that he "fiddled".

Though I'm running across this a bit late, the odometer you refer to was invented by Archimedes. Before the Romans went to war with Sicily, they hired him to develop a way to measure a mile accurately. And as you said, Da Vinci used the description of the device to try to make one, but use the type of gears typical in the renaissance. The triangular toothed gears would have been easier for the ancients to make with a file.

The question shouldn't be "How did the Romans build strait roads?" The question should be "Why couldn't anyone else build a strait road?" I am perplexed personally, how there are so many people who don't understand basic mechanical concepts and keep insisting that everything that ancient people did were all so mysterious and impossible to understand. Everything from ancient pyramids to ancient Rome to the Incas and Aztecs and Mayans. Light travels in a mostly strait line so all you have to do is follow light to get a strait road. You should be able to keep any road strait at least on a mile by mile basis to within a few feet using nothing but your eye and a half way decent amount of sunlight barring obstructions that one might have to go around. All you do is eyeball it. You eyeball as far as you can and most people can eyeball a mile or more with 30 seconds of training. Then you go to about half way along that mile and you line up an additional half mile with the half mile remaining ahead of you. This will keep a road strait to within a few hundred feet every mile which while admittedly isn't perfect it is straiter than 90% of all the roads in the US today. Add in one solid marker and track the sun and you can get an even better strait line to within a few feet for every mile. Now you want something damned near perfect you have a line of men a few hundred feet apart from each other for the length of road in question. have every one of them have a marking pole at the ready. Then when the shadow of the sun hits the spot where the road begins then have each and every man in the line mark the road where the shadow hits. Again this isn't perfect and will if long enough result in a curve but for a north to south road it should be pretty strait if everyone is at the same altitude. One can use long poles to correct for altitude if one knows the altitude of each spot which the ancients in Greece had a pretty good handle on thanks to Hipparchus. In fact trigonometry has been used in European construction ever since. Even before Hipparchus came up with trigonometry ancient Greeks, Egyptians and others came up with work arounds.

Dude, Nero's servants STARTED THE FIRE so Nero could rebuild Roma in his own image. The crime solely belonged to him. The early Christian sources are 100% correct and they did not lie. Nero was a MONSTER and whoever excuses his crimes or covers up for him is also a MONSTER.

This video has a ton of WRONG INFO. Streets in the city had paved/stone surface,roads were build outside of the city,made of smooth gravel. This is very a common mistake. Roman horses had their feet naked,no horseshoe on Roman horses. Then you have a 5 metric tons (max payload) wooden wheels cart,very massive running all over the Empire. Roman roads are like modern highways,same principals all over the Empire,same methods. Wood wheels do not run over stones fine,like horses with no horseshoe,so no paved roads. Street(via)=stone road=gravel. Roman Roads are truly massive,by far much more impressive than any paved Roman street. Almost every people I know have the same wrong concept in their minds,even well educated people. This subject is well know from centuries,but We still think in stone paved street as Roman roads, those are city streets,thought to walk over it mostly. Most of the true Roman roads are in the middle of nowhere fossilized and buried underground,cos in many places they were unused by centuries. It is something relatively new the discovery of some of this roads,you need a plane and LIDAR images and very good historic clues to find them.

Technically 'decimated' means to remove 10% of 'something'. It came from an ancient Roman military disciplinary action. If a general et al, was not happy with his troops performance, 10% of them would be killed.

Always interesting looking back and observing. You can have a more objective and dispassionate view of things but it will lack something for the audience of course. Which is probably who the original writers were considering or selling to. I’m pretty sure we all knew those historians were looking at the event through a tainted lens however reputable they may have been. The details seems to support the premises of myth and biased against Nero, yet as the time equates with ego, cruel treatment of differing classes and his own apparent questionable mental health; probably he was not exactly fully responsible with his actions of the time. There could’ve been a simple plan put in place to have the fire started while he is away and he comes back to pass himself off as the hero while gaining access to property he needed for his new project? But what information would support that except what came to light years later? Conjecture is always fun, lol. Of course it does make sense the details of opening up his garden for the displaced and performing for them and that becoming the basis for his playing an instrument (that did not exist yet) and watching it burn (there always seems to be at least a little truth within the myth). Anyway, nice job but I guess we still don’t know “the rest of the story” just yet.

The Romans are a small blip in the history of Britain. Before them is a whole plethora of cultures and the impact that each had on the countryside and topography in general are all well documented. There is good reason to believe that many of the roads attributed to the Romans were already “set out” and being used by the long distant travellers of eras before. The method of laying a straight Walkway, as apposed to building a road, relied upon feelings that relate to water-dowsing, in as much as that the long distance walker was usually a holy-man/ Druid. It has long been established in this country that ley lines are the geodesic compass of these men, and that they traverse this country. Those that were sensitive to the transmissions/ vibrations from natural geological faults, could range the whole country over, with important buildings or markers being erected at important junctions of these ley lines. That the Romans built roads to convey whole armies and their associated wagonloads of (everything), then it is fair to say ‘that they would be cutting of their nose to spite their face’, to not use an already well established line-of-March, so to speak.

This video doesn't really answer the question -- the assertion is made that 'surveyors would set markers on points like hills', but the question is how that was done in such a way to ensure the road was straight. I haven't come across a good explanation for how that would be done.

I tried to find an answer for you but it seems that what I found is pretty much the same as what Simon said in the video. I did find one thing that I'm not sure was mentioned in the video, I may have totally missed Simon mentioning it. I'm gonna paste the answers that I found along with the links to where I got them at the bottom of this comment. "The simple answer is that they used a form of surveying tool called a groma. This basically consisted of two pieces of wood nailed together to form a square cross with right angles in all corners. Each piece of wood had lead weights attached to the end, and they determined they had a straight line when the lead weight from one piece of wood lined up with the one in front of it. Wood posts would be used to stake out the boundaries of the road in order to help maintain a straight line over an extended distance." - history.stackexchange.com/questions/8971/how-did-the-romans-build-straight-roads-that-stretched-very-long-distances "Of course, you would think certain natural features - steep hills and valleys - of the landscape could affect the straightness of the via munita. Not so, Roman roads went straight up the most precipitous of slopes without winding back and forth in hairpin bends like modern roads. This is because a marching man on foot can go straight up a steep hill and then rest to recover before moving on much quicker than if he wound around a gently rising slope." - www.historyextra.com/period/roman/why-did-romans-build-straight-roads-lines/ This is one of the tools that was uses along with the Groma "Chorobates The chorobates is described as a rod 20ft long with duplicate legs attached perpendicularly at each end. Diagonals connect the rods and legs. Both diagonal members have vertical lines scriven in them over which plumb bobs hang. When the instrument is in position and the plumb lines strike both the scribe lines the instrument is level. If the wind interferes the water level at the top of the horizontal is used. Vitruvius instructs the groove should be 5 ft long 1 digit wide and 1.5 digits deep." I couldn't get a link for that because it came from a PDF. But the title of the paper and the author is.
