The stuff on the early period could still do with some work.
On
1600 TILL 1800 JANISSARY CORPS
This picture:
needs a caption as
a Janissary by Hans Weigel, 1577
The
long white ostrich feather plumes were not invented by Knotel, he based it on
a Janissary by Nicolas de Nicolay, 1577
The Janissary Corps Musketeers' buttoned kaftan is painted in various colours, yet was actually a uniform yellow or blue (as can be seen from these original pictures).
Knotel may have made up the stripes but
Ottoman miniatures show also green, red & black. I would have used 'solid colours' rather than "uniform" so as not to give the impression a unit all wore the same colour, unless he can prove they did in the 17th century.
Pictures from an
Album of Ottoman Soldiers dated 1805 which I wish he could have identified:
have a long s:
ſ in the captions.
Bimbascha should be Bimbascha not Bimbalcha.
Janitscharen should be Janitscharen not Janitjcharen.
On the same page there is a link to a Janissary on my
Melchior Lorck, 1570-83, site but no mention that
Melchior Lorck has a Janissary with an enormous plume
Figure A, as he notes in a footnote, appears in
The Costume of Turkey, Illustrated by a Series of Engravings, 1802 as "a Spahi, belonging to one of the Asiatic provinces", so he should do away with
Figure 'A': is identified specifically as a "SIPAHI TIMARIOTE" [1]. Which appears to identify him as a member of the Household cavalry.
I don't know much about 19th century Ottomans but on this page
THE FIRST MODERN OTTOMAN ARMY UNIFORMS 1800 TILL 1826 has this claim:
It should be noted, that a print illustration of 1808 Ottoman new army soldier clearly identifies a soldier (which can be dated to 1807-08 by the particular headgear he is wearing), as a "Soldier of the Bostandjees, or Corps from the Sultan's Gardeners" (New York Public Library's Digital Gallery, the Vinkhuizjen Collection). This primary evidence presents a very different picture of the origins of the soldiers in the new army, as part of the Sultan's personnel household.
The Vinkhuizjen Collection is not a primary source. Vinkhuizjen cut pictures out of books which were pasted in albums, losing most of the provenance and most of any text in these books. The dates Vinkhuizjen penciled on these are often the date of publication rather than the date the image represents or the date of the art it is based on. This can vary by decades and centuries.
On the
NAPOLEONIC OTTOMAN JANISSARY CORPS UNIFORMS page is this image:
which has been stitched together after Vinkhuizjen cut it into pieces (so he had more pictures).
More effort would be needed to find all Vinkhuizjen's sources.
There is no "print illustration of 1808 Ottoman new army soldier" with that date in the Vinkhuizjen Collection but this plate:
dated 1817 by Vinkhuizjen is the one referred to. Vinkhuizjen has cut the caption "Soldier of ditto" from the contents page of
McLean's The Military Costume of Turkey. Without the line that appeared above it the caption is useless.
This picture on the
fantasy Janissary costume page:
may have appeared in 1880-1900 illustrated encyclopaedias, as noted, but it is from
Elbicei Atika. Musée des Anciens Costumes Turcs de Constantinople, par Jean Brindesi, 1855. It also appeared on
a set of Turkish postcards made in the 1950s.
