Map Features - scale line


Return to list of Features
In order by date from the Map group (maker year).
Typical illustrated examples are described, NOT ALL examples.
The mile on the scale line of early maps is not a statute mile but the map itself can be used to estimate the "Old English Mile" used.
NB absence of evidence is not evidence of absence
Waldseemuller 1513
 (scale line; scale)
Printed in the lower right border is a:-
Scala Miliario[ ] Italia
graduated in 10s and 100s labelled in 100 miles. The 700 miles = 120 mm giving a scale:-
148 italian miles to 1 inch
Lily 1546
 (scale line)
Printed lower right is a scale of:-
MILLIARIA
200 miles chequered in 5 mile intervals, labelled at 20 mile intervals; be careful how you read the scale, the figures belong at the end of the interval, not the middle where they are printed.
Mercator 1564
 (scale line; scale)
Printed lower centre is a scale line:-
Scala miliarum Anglicorum
50 miles graduated in miles, labelled in 10s. The map scale (from Shirley) is about:-
14 miles to 1 inch
The south coast of England is about 15% too long.
The museum label at Duisburg states a scale about:-
1 to 920000
14.5 miles to 1 inch
Lloyd 1573
 (scale line; scale)
Printed upper right is:-


Scala miliarum Anglicorum
with 80 miles, chequered at 5 mile intervals, labelled at 10 miles intervals. The length of the scale line is uncertain, the ends are slanted! Taking 80 miles = 97 mm gives a scale 1 to 1327294. The map scale is about:-
1 to 1300000
But a better estimate comes from considering the position of a few major towns, giving a map scale about:-
1 to 1500000
24 miles to 1 inch
Saxton 1575
 (scale line; scale; dividers)
There is a scale line of 10 miles, chequered in half miles, caption:-
Scala Miliarum


There is a pair of dividers above. The 10 miles = 83.2 mm, giving, wrongly assuming a statute mile for the map maker's mile, a map scale about:-
1 to 190000 ?
3 miles to 1 inch
A better estimate can be made from town positions, comparing known town-town distances. The map scale is about:-
1 to 240000
4 miles to 1 inch
The map maker's mile is an:-
Old English Mile = 1.22 statute miles
Saxton 1579
 (scale line; map maker; engraver)
Printed lower left in a slightly restrained strapwork cartouche is a:-


Scala Miliarium
The 50 miles is divided at 1/2 miles, labelled at 5 mile intervals. Above the scale is a splendid pair of dividers with a scroll draped on them:-


Christophorus Saxton descripsit.
In a cartouche below the scale is:-
Augustinus Ryther Anglus Sculpsit. Ano. Dni~. 1579.
Augustine Ryther was a Fleming emigrant to England, proud to call himself 'Anglus'. He engraved 5 of the county maps in Saxton's set of counties.
Waghenaer 1583
 (scale lines)
The map has three scale lines:-
English leagues 20 in a degree
with 7 numbered divisions,
Spanish leagues [17 1/2] in a degree
with 6 numbered divisions,
Dutch leagues [15] in a degree
with 5 numbered divisions. These are presented in a strapwork cartouche lower left.
(The size of the original map is given as 19.5 x 12.75 inches, sheet or map not stated, and I make no attempt to calculate a scale from the copied reproduction.)
Petri 1588
 (scale line)
Printed lower centre is a scale line of:-
Miliara Anglica
The 100 miles are chequered in 5 mile intervals, labelled at 10 mile intervals.
Adams 1590
 (scale line; scale; map maker; engraver)
Printed lower left in a strapwork cartouche, below one of the coats of arms, is:-
The Scale of Leagues, every league co~teining 3 miles Ro: Adamo Authore
The scale line is graduated in leagues, labelled 1,2..5, 10, 15, ...50. The 50 leagues = 91.1 mm. Making an [unwarranted] assumption that a league = 3 nautical miles of 6080 feet then the map scale is 1 to 3051345; the map scale is about:-
1 to 3000000
50 (land) miles to 1 inch
Printed below the scale line:-
Augustinus Ryther Sculpsit
Other estimates of the map scale can be got from measuring between some towns:-
London - Bristol = 105mm (174.1Km)
giving a scale 1 to 1658095, say 1 to 1600000
London - York = 99mm (280.6Km)
giving a scale 1 to 2834343, say 1 to 2800000
As is pretty clear from its appearance, the map is much too long E-W.
Mercator 1595
 (scale; scale lines)
The map has two scale lines:-


Miliaria Anglica magna
chequered at 2 mile intervals, 22 miles = 29.2mm is 1 to 1212519 assuming a statute mile, ie about:-
1 to 1200000
and:-
parva
chequered at 1 mile intervals, 20 miles = 24.1mm is 1 to 1335555, ie about:-
1 to 1300000
making the same bad assumption. The map scale is about:-
20 miles to 1 inch
Using the latitude scale, 2 degrees latitude = 129.6mm is 1 to 1731985, about:-
1 to 1700000
27 miles to 1 inch
Norden 1595 ms
 (scale line; index grid)
There is no small scale line on the map.
There is an overall grid of squares in the borders which are believed to be in miles, chequered at half mile intervals.
Norden 1595
 (scale line; scale; index grid)
Printed at the foot of the table of hundreds it says:-
The scale of miles goeth rounde about the Mapp


All four map borders are chequered to show miles, west-east and north-south; the origin of the scales is top left. Each two miles is labelled across top and bottom, 2, 4, 6, ... 48. The labelling on the sides runs down a, b, c, ... x (no 'i' or 'u'). Besides being scale lines the scales and the grid printed across the map in fine lines make an index grid. John Norden's provision of an index grid is an innovation in map making.
The scale can be estimated from the scale line:-
48 miles = 400.5 mm
Wrongly assuming a modern statute miles this gives a scale 1 to 192880; the map scale is about:-
1 to 190000
3 miles to 1 inch
A better estimate of scale has been estimated from the positions of towns, also providing a value of the 'old english mile' used in Norden in 1595. The map scale is about 1 to 241379, say:-
1 to 240000
4 miles to 1 inch
Norden uses an:-
Old English Mile = 1.24 statute miles
Keer 1604
 (scale line)
A strapwork cartouche lower centre has a scale of:-
Milliaria Anglicana
This has 60 miles chequered in 5 mile intervals, labelled at 10 miles intervals. Above is a pair of dividers.
Keer 1605
 (scale line; scale)
In the lower of the title cartouches is a scale line 10 miles, chequered in miles, labelled:-
Sala Miliarum


10 miles = 18.8mm, wrongly assuming a modern statute mile - the scale is thus 1 to 856034. The map scale is about:-
1 to 860000
14 miles to 1 inch
A better estimate of the scale is made from town positions, comparing to known town-town distances. The map scale is about:-
1 to 1100000
16.5 miles to 1 inch
The map maker's mile is an:-
Old English Mile = 1.25 statute miles
Norden 1607
 (scale line; scale)


The scale line of 10 miles is chequered in half miles. The 10 miles = 66.4 mm, giving a scale 1 to 243300, on the bad assumption of a modern statute mile. The map scale is about:-
1 to 240000
4 miles to 1 inch
An estimate of scale can be made from town positions, comparing known town-town distances. The map scale is about:-
1 to 380000
6 miles to 1 inch
The map maker's mile is an:-
Old English Mile = 1.24 statute miles
Speed 1611
 (scale line; scale; map maker)
Printed lower left is a scale line in a strapwork cartouche decorated with cherubs holding a globe and dividers, with a banner:-
Performed by John Speede
In the cartouche labelled:-
The Scale of Miles
are two scales. The upper is chequered in 5 miles intervals labelled in tens, for:-
Common :Mill.
which has 80 miles = 57.1 mm giving a scale 1 to 2254773, a map scale about:-
1 to 2300000
36 miles to 1 inch
These are the map maker's miles which seem to be about 1.4 statute mile, which had not become statute at that period. The map provides an estimate of the common Old English Mile = 1.4 statute mile, greater than the usual range of values for this obscure historical unit.
The lower scale is:-
By Degrees
which has 100 miles in the place of 80 common miles. This gives a scale about:-
1 to 2800000
44 miles to 1 inch
and I don't know how to imterpret this!
It would be possible to get a good estimate of the map's scale by measuring the positions of a couple of dozen towns and comparing their distances from each other with their known distances - a fair bit of work.
Bertius 1616
 (scale line; scale)
Printed lower right is a scale of:-


Miliaria Anglica
in a strapwork cartouche. This has 30 miles chequered in 2 mile intervals, labelled in 10 mile groups. The 30 miles = 17.1 mm giving a scale 1 to 2823410 on the bad assumption that the mile is a modern statute mile. The map scale is about:-
1 to 2800000
45 miles to 1 inch
Bill 1626
 (scale line; scale)


Printed below the title, upper left, is:-
A Scale of Miles
The scale has 10 miles, marked at 1 mile intervals, labelled at 5 and 10 miles. The 10 miles = 19.8 mm gives a scale 1 to 812800 on the improper assumption of a modern statute mile, the map scale is about:-
1 to 810000
13 miles to 1 inch
A better estimate of the map's scale can be got from the positions of a number of towns. Using DISTTAB.exe to do the sums this gives a scale 1 to 1057911; the map scale is about:-
1 to 1100000
16.5 miles to 1 inch
and the map's 'mile' is an:-
Old English Mile = 1.31 statute miles
Simmons 1635
 (scale line; scale; dividers)


A scale line of ten miles, chequered in miles, is given. This is fitted into the table neatly, so it is at a peculiar angle to the map; it is still useable.
Estimating from the scale line, 10 miles = 11 mm, and making the bad assumption that the mile is a modern statute mile, the map scale is roughly:-
1 to 1500000
23 miles to 1 inch.
A pair of compasses are drawn over the scale line. These are distorted; to make them fit the space one leg is much longer than the other.
Another estimate of the scale can be made from town positions, comparing known town-town distances. The map scale is about:-
1 to 1600000
25.5 miles to 1 inch
The map maker's mile is an:-
Old English Mile = 1.10 statute miles
As the map is so tiny, this is a poor estimate of the old english mile.
Dankerts 1640s-50s
 (scale lines; scale)
There are two scale lines printed lower right; french, german miles, eg:-
Miliaria Gallica Sive horae itineris 20 in uno Gradu.
chequered and labelled in minutes. The 'miles' are leagues. The 30 miles = 132.4 mm gives a scale 1 to 1259717, assuming a league of 3 nautical miles of 6080 feet. The chart scale is about:-
1 to 1260000
6 leagues to 1 inch
20 statute miles to 1 inch
Jacobsz 1643
 (scale lines; scale)
Printed lower left are three scale lines; dutch miles, spanish miles, and english and french miles. The english/french scale has:-
Engels. en Frans. mylen 20 in een Graadt
graduated in miles. This is a mistake; for miles read leagues. The 16 miles = 161.2 mm gives a scale 1 to 551817, assuming 'mile' to be a league of 3 nautical miles of 6080 feet. The chart scale is about:-
1 to 550000
2.5 leagues to 1 inch
9 statute miles to 1 inch
Hollar 1644
 (scale line; scale)
Printed below the title lower right is a scale of:-
English Miles
chequered in miles, labelled at 5 miles intervals. The 20 miles = 84.8 mm giving a scale 1 to 379401 wrongly assuming that the miles are statute miles. The map scale is (wrongly):-
1 to 380000
6 miles to 1 inch
A much more reliable estimate is got from measuring the positions of towns and comparing these to known positions.
The map scale is about 1 to 456826 +-8%. The map scale is about:-
1 to 460000
7 miles to 1 inch
The measurement provides an estimate of the miles used in the map, the Old English Mile:-
1 map mile = 1.21 statute miles
Blaeu 1645
 (scale line; scale)
The map has a scale line of 4 miles, chequered iin quarter miles:-


Mill. Angl. quoru~ 4 uni Germanico aequip.
The scale line 4 miles = 37.1mm, gives a scale 1 to 173589 wrongly assuming a modern mile this is about:-
1 to 170000 ?
3 miles to 1 inch
The map size is:-
wxh, plate: 516x420mm
A much better estimate is got by comparing the positions of a number of towns with their known positions (assumed from NGR values); the processing was done with a computer program, DISTTAB.exe. From this the map scale is 1 to 218129, ie about:-
1 to 220000
3.5 miles to 1 inch
and we get an estimate of Blaeu's map miles, an:-
Old English Mile = 1.26 statute mile
Jansson 1646
 (scale lines; scale)
Printed upper right is a scroll cartouche with two scale lines:-


Milliari Anglica.
Milliari Germanica.
english miles and german miles, the latter being 4 english miles each.
The english scale line is chequered and labelled at 1 mile intervals. 6 miles = 47.5mm (561 pixels at 300dpi) giving a map scale 1 to 203294 on the bad assumption of an english statute mile. The map scale is about:-
1 to 200000 ?
3 miles to 1 inch
A more reliable estimate of the scale is got by comparing the positions of a selection of places with their known positions. From this procedure the map scale is 1 to 249721, about:-
1 to 250000 ?
4 miles to 1 inch
The map's english mile is:-
old english mile = 1.23 statute miles
Goos 1665
 (scale lines; scale)
Printed lower right are three scale lines; dutch, spanish, english and french. For example:-
Eng: en Fr: mijlen 20 in een graad / Frensh and English miles 20 to a degree
graduated in 1s to 10, then in 5s, labelled in 5s. The 35 miles = 169.7 mm, assuming a 'mile' is a league of 3 nautical miles of 6080 feet, this gives a scale 1 to 1146637. The chart scale is about:-
1 to 1100000
5 leagues to 1 inch
18 statute miles to 1 inch
Carr 1668
 (scale line)
Printed with the coat of arms is a scale line.
Blome 1673
 (scale line; scale)
Printed lower centre is:-


A Scale of 10 Miles
chequered and labelled in miles. The 10 miles = 65.1mm gives a scale 1 to 247211 on the bad assumption of a statute mile. The map scale is about:-
1 to 250000
4 miles to 1 inch
A better estimate of the map scale, with a note about the Old English Mile, has been made.
Ogilby 1675
 (scale lines; scale)
Printed in a scroll cartouche lower left are three scale lines, headed:-
A Scale of Miles
Each is chequered in miles, marked at 5 miles and labelled at 10 mile intervals, and has 50 miles in the scale. They are labelled:-
Vulgar Computed Miles 23 in an Inch


Direct Horizontal Miles 26 in an Inch
Dimensurated Road Miles 29 in an I.
The direct horizontal miles would seem to be the map's 'proper' scale, its 50 miles = 48.7 mm gives a scale 1 to 1652304 ie 26.1 miles to 1 inch. John Ogilby declares, elsewhere, that his mile is 1760 yards, a statute mile. The map scale is about:-
1 to 1700000
26 miles to 1 inch
John Ogilby's vulgar miles are larger, 1.12 statute miles according to his scale line. This is perhaps his estimate of an Old English Mile?
The measured road miles provides an estimate of the twistiness of a road? A mile by road achieving only 0.9 miles directly.
The positions of places in Hampshire on the map can be compared to their known places, using DISTTAB.exe software, which gives a different estimate of the map scale, 1 to 1755918, 27 miles to 1 inch. It is unfair to measure such a small part of the map; the confidence in these measurements is small (+-18%).
Morden 1676
 (scale line)
The scale line is 10 miles, chequered in miles; 10 miles =10.4mm gives a scale about 1 to 1547446 assuming a modern statute mile. Ie the map scale is about:-
1 to 1550000
24 miles to 1 inch.
There is a pair of dividers above the scale line.
Another estimate of scale can be made from town positions, comparing known town-town distances. The map scale is about:-
1 to 1800000
27.5 miles to 1 inch
The map maker's mile is an:-
Old English Mile = 1.15 staute miles
but this is such a small map that this is not a good measure of the old english mile.
Morden 1676
 (scale line; scale)


The scale line of 10 miles is chequered at one mile intervals, labelled at 5 and 10 and:-
Miles
The length is 10.3mm, assuming a statute mile the scale is 1 to 1562470, ie a map scale about:-
1 to 1600000 ?
25 miles to 1 inch
whatever the miles might be.
The sheet has been trimmed recently, perhaps by a map dealer? It is not possible to tell if the Hampshire map was alone on a sheet or accompanied by another map - but, the trimming might have been occasioned by separating two maps from one sheet.
wxh, sheet = 6x8.5cm
wxh, map = 56x58mm, excluding the top and bottom caption areas.
Blome 1681
 (scale line; scale)
There is a scale line, chequered in miles:-


A Scale of 4 Miles
The 4 miles of the scale line are about 9 1/2 miles! A better estimate of the map scale is got by measuring town positions and comparing these to known positions, now. This was done with DISTTAB.exe, giving a map scale 7.73 statute miles to 1 inch, 1 to 489761. The scale is about:-
1 to 490000 ?
7.5 miles to 1 inch
The map's mile is 2.4 statute miles. It is more likely that the scale line is incorrectly labelled; it is an 8 mile scale not a 4 mile scale. Assuming this then the map mile is an:-
Old English Mile = 1.21 statute miles
van Keulen c1681
 (scale lines; scale)
Printed upper centre are four scale lines; dutch miles, english and french leagues, spanish leagues, and 'suetsche' miles. The english/french scale has:-
Lieues de France de 20 de Degre. - English Leagues 20 for Degree
chequered and labelled in leagues; the first league chequered in thirds, ie nautical miles. The 24 leagues = 186.8 mm giving a scale 1 to 714289 assuming a league of 3 nautical miles of 6080 feet. The chart scale is about:-
1 to 710000
3 leagues to 1 inch
11 statute miles to 1 inch
Lea 1687
 (scale lines; scale)
Printed lower right are three scale lines, labelled:-
MILES
Magna
Mediocra
Parva
each chequered in miles for 10 miles, then graduated at 5 miles intervals, labelled at 10 mile intervals.
The large miles have 30 miles = 50.6 mm giving a scale 1 to 1577788, a map scale about:-
1 to 1600000
25 miles to 1 inch
The middle miles have 35 miles = 52.1 mm giving a scale 1 to 1081133, a map scale about:-
1 to 1100000
17 miles to 1 inch
The small miles have 40 miles = 55.2 mm giving a scale 1 to 1166191, a map scale about:-
1200000
18 miles to 1 inch
Morden 1688
 (scale line; scale)
There is a scale of:-
English Leagues
chequered at 2 league intervals, labelled 2,4,6,8,10,20. The 20 leagues = 46.1 mm gives a scale 1 to 2411953; the map scale is about:-
1 to 2500000
38 miles to 1 inch
11 leagues to 1 inch
assuming a league = 3 nautical miles of 6080 feet.
Lea 1689

Collins 1693
 (scale; scale line)
Printed below the dedication on the left is:-


A Scale of Miles
The line is chequered and labelled in miles, 1..6; 6 sea miles = 106.9mm. Assuming these are sea miles, 6082.95ft at this latitude, the map scale is 1 to 104065; the map scale is about:-
1 to 100000
1 1/2 sea miles to 1 inch
Collins 1693
 (scale line)
The chart has a scale line of 6 miles = 107.6mm. Assuming a sea mile 6082.93ft the scale of the chart is 1 to 103387, ie scale about:-
1 to 100000
1.4 sea miles to 1 inch
1.6 miles to 1 inch
Seller 1694
 (scale line; scale)
A scale line:-


Scale of Miles
has ten miles, chequered at the first mile and at two mile intervals. 1 to miles is 26.4mm giving a scale 1 to 609600, wrongly assuming a modern statute mile. The map scale is about:-
1 to 610000
10 miles to 1 inch
A better estimate of scale can be made from town positions, comparing known town-town distances. Measured from another copy of the same map the map scale is about:-
1 to 830000
13 miles to 1 inch
The map maker's mile is an:-
Old English Mile = 1.26 statute miles
Morden 1695
 (scale lines; scale)


There are two scale lines, each 10 miles divided into miles. The two scales, from the scale lines, are 1 to 197708 and 1 to 216601 using the bad assumption of a modern statute mile. The map scale is about:-
1 to 200000 or 220000
3 or 3.5 miles to 1 inch
A better estimate of the scale can be made from town positions, comparing known town-town distances. The map scale is about:-
1 to 30000
5 miles to 1 inch
The map maker's miles are an:-

chequered in leagues, labelled at 5 league intervals. The 20 leagues = 129.4 mm gives a scale 1 to 858282, assuming a league of 3 nautical miles of 6080 feet. The chart scale is about:-
1 to 860000
4 leagues to 1 inch
13.5 statute mile to 1 inch

The map has a scale line:-
Scale of English Miles
a line with mile marks, laballed 1..5, 5 miles = 24.4 mm, giving a scale 1 to 329784, ie the map scale is about:-
1 to 330000
5 miles to 1 inch
Ramble 1845
 (scale line; scale)
Printed lower right is a:-


Scale of Miles
chequered at 2 miles intervals; on this 10 miles = 11.9mm, giving a scale 1 to 1352390, ie the map scale, perhaps E-W only, is about:-
1 to 1400000
21 miles to 1 inch
But, the map is distorted, stretched out in N-S direction. The latitude scale gives a quite different estimate of scale, 40 minutes latitude = 77.1mm, giving 1 to 962545, the map scale N-S is about:-
1 to 960000
15 miles to 1 inch

Brannon 1859
 (scale line; scale)
Printed lower left os a:-


Scale of 3 Miles to one Inch
graduated and labelled in miles from 0 to 9, and a leftward part graduated in quarter miles, labelled 1/2 and 1. The 9+1 miles = 82.1 mm giving a scale 1 to 196022 assuming a statute mile; the map scale is about:-
1 to 200000
3 miles to 1 inch
From measuring the position of the 21 towns in Hampshire and comparing them with their 'correct' positions, it is possible to get other estimates of the scale. This process uses DISTTAB.exe software. The map scale is about 1 to 193103, that is:-
1 to 190000
3 statute miles to 1 inch
or using the scale line, 1 to 196364, that is:-
1 to 190000
3.10 map miles to 1 inch
map mile = 0.98 statute mile
The correlation between town to town distances on the map to 'correct' distances is 1.00.

The 5+1 miles = 151.8 mm giving a scale 1 to 63610. In the right border a plainer vertical scale of miles, north-south, is 4+1 miles = 127.2 mm giving a scale 1 to 63260. The map scale is nominally:-
1 to 63360
1 inch to 1 mile
Printed above the bottom scale line:-


Scale of One Inch to One Statute Mile 1/63360
Apart from the inevitable stretch and shrink of paper with change of relative humidity these maps are reliably accurate in their scale. The map's projection has associated errors which are not significant in these small scale maps.
