all according to dad's everywhere having to stop and ask
- 00:32
for directions well one of the most popular medieval navigational
- 00:36
tools was called come out no it wasn't a camel
- 00:40
with a perfectly good sense of direction They were basically
- 00:42
simple wooden blocks with complex markings on them Those living
- 00:47
near the equator could use the markings and the stars
- 00:49
to determine their latitude Almost people gave them and enthusiastic

two thumbs up for not steering them into madagascar On
- 00:56
accident the leamer is freak out interrupt their beauty sleep
- 01:00
come owls were developed by arabs european traders almost exclusively
- 01:05
stuck to coastlines Arab sailors however sailed deep into the
- 01:09
indian ocean and down the dangerous coast of east africa
- 01:13
Well the kamal was an essential part of getting their

under the sea Right Well basket obama The portuguese explorer

was introduced to the come on while visiting india in

fourteen Ninety eight Well not long after europeans it after
- 01:39
the idea into an instrument called the crossed staff Ten
- 01:42
bucks says that they said it was their idea to
- 01:45
begin with One popular instrument for europe was the astro
- 01:48
lab Well for non equatorial places like medieval europe astro
- 01:53
lab was where it was at astro labs were circular
- 01:57
brass object designed to measure the angle between the horizon
- 02:01
and the son or any nice bright star They did
- 02:04
have problems though they weren't always accurate Like when our
- 02:07
gps tells us turn left right off of a bridge
- 02:11
And astra lobs were especially inaccurate on the rough seas
- 02:14
So great One thing worse than being on the high

seas in the storm is being completely lost while on
- 02:21
the high seas in the storm but hey you get
- 02:23
what you pay for Those things are probably way cheaper
- 02:26
than our gps We'll compasses back then were also a
- 02:29
thing The chinese had reliable magnetized compass is by one
- 02:33
thousand see eat but they rarely use them on ships
- 02:36
For some reason Go figure the venetians got more serious
- 02:40
about them in the thirteenth century with compasses only tell
- 02:44
us where north is That means we still have to
- 02:46
use other technology to figure out you know where the
- 02:49
heck we are And for those of us who weren't
- 02:52
in the scouts we'd also have to figure out how
- 02:55
to use a compass Because believe it or not they
