Interdisciplinary l:.nquiry
Jln
by P. H. Blyth ABSTRACT Asiatic archers proved less successful against armoured troops' eluring the Persian invasion of Greece than •
used
their succe6sors in TIoman and Byzantine ti�es, who similar-looking bows.
Apparently,
quite small variations in
arT:lour or weapono could tip the balance,
but they can onl,. be
discerneel using the historical evidencc and the growing bod,. prin ciple s
of archsoologicRl material if the technological .
under-
governing the dcsign of ancient \-/capon6 and armour �re stood.
This study seeks to inve st ig a te an d app ly sOlDe of

Preface
In presenting a thesis for the Degree of Do�tor of Philosophy, the writer naturally expects his work to be •
ing
judged by the highest standards; however, in a wide-
enquiry, which must be completed in a limited time, it is not possible to profess expert knowledge in all departments. I would therefore ask the reader to regard this work as primarily that of an historian,
seeking new sources of
information in technical fields where he is necessarily an
amateur,
and to judge his success not so much by the
completeness of his knowledge there, but by the relevance of
his observations to the historical problem, and their
general +.ruth.
If the overall trend of the argllment, and
the detailed historical interpretation in the last two chapters, win acceptance, I hope that occasional crudi ties elsewhere may be either overlooked or corrected by others.

Dedication
To my colleagues in the Teaching profession, in the hope that it may help toward the improvement of specialist education.

A r.KNOWLETG F!rJ/E:NTS
This study would not have been possible without the foresight,
generosity,
and cooperation of many people and
It does not often happen that a
several institutions. man
in his forties, in the junior ranks of the Teaching
pr of es sio n, and with a sizeable fa�ily to support is given •
the leisure,
the facilities,
and the assistance to compose
o·
a work which lies so far beyond the confines of his previous knowledge and competence. they were amply met, commensurate,
The requirements were large,
and I hope that my gratitude is
and that the work will provide some repayment.
The enqui ry has been s.'pported from an early stage by the Leverhulme tru.st;
I am most grat�ful to the Trllstees
for enabling the University of Reading to provide a salary sufficient to ensure peace of mind in spite of inflation
and my family responsibilities, and for grants to cover travel and materials.
My
gl'at i tude is also due to the
Vice-Chancellor and Senate of the University for admitting me to a Research Fellowship and me�bership of the Academic Staff, with all the facilities that that implies, for the duration of my re s earch .
The concept of an interdisciplina;ry study using the �ethods of the engineer to contribute to Ancient History was due to Professor A.W.H.Adkins then Frofessor of Classics, and to Professor J.E.Gordon, Profes8vr of Ma terials Technology,
both of Reading University.
This
study was begun under their joint supeI'vision, and completed und�r that of Profesoor Gordon alone, after
Professor Adkins'
departure.
I
am
grateful to them both
for my introduction to the subject and for continual help
•
and encouragement, but particularly to Professor Gordon who has been my chief tutor in scientific matters and much •
else besides.
The choice of topic, however,
is my own,
and neither is in any way responsible for the views expressed.
•
For provision of laboratory and office facilities I vlish to thank Professor P.B.Fellgett,
and Professor '-I.Hirst,
successively heads of the Department of Engineering and Cybernetics, especially Professor Hirst for his personal int'arest in the project and the loan of the compressed air device mentioned in chapter 5.
•
For tuition and help
in engineering and other scientific matters, and also for companionship, encouragement,
discussion and suggestions
lowe a great debt to Professor W.D.Biggs,
and Drs.A.J.Pretlo7e,
C.R.Chaplin, J.F.V.Vincent, P.J.!iusgrove, R.S.Dobbs and
G.Jeronimidis.
My debt to Dr.Jeronimidis is parti cul arl y
great, since he· has not only coped endlessly with my mathematical .
shortcomings but also conducted research on my behalf in Rome, presented in Appendix 3.1.
•
In the depart:1ent of Classics,
I an
grateful to •
Mr.F.Robertson, successor to Professor Adkins ss head of department, and to Dr.J.G.T.e.nde1a, for facilities , dis cus sion, and the provision of contacts.
I also reme�ber with special
sratitude the late Dr.A.n.Ure, Curator of the University -
Classical museum.
Beoause of the respect and affection in
which she was held throughout the world of Classical Archaeology, the introductions to distinguished scholars with which she
comple,nented her advi,oo
were
always most warmly received.
For opport�nities to examine ar�our and archery equipment in this country I am grateful to Mr. Ij' ayne s , then Keeper of Greek and Roman Antiqui ties at the British Museum,
·ooth
for his personal assista.nce and that of his staff;
to the

We shcll therefore
briefly describe the Scythinn <�d Persian bows (2.,.1.1,
2.5.1.2) �nd then confine our �ttention to three points which ar c relevent to t he evidence on the nrrow al rea dy d iscussed . Thes(: �re;

and a comparison (2, .5 . 4) bet\o;een the energies so estirnDted •
�nd those produced by la t e r types of bow .
It is obse:J:·vcd
that the cstimctes gi ven for Scythion and P e rs inn orrows are lo w compa red with the energy of arrows shot from the English longbow Dnd of those froo the Turkish bow, and soae possible reasons are sug g est e d.

In 0.62 !liill plate the resistance of the plate dropped by more than 50% when the plate split. In plate it dropped by about 20%. The figure for 1!0 mni plate gives the actual r0sistance rocorded..

-
error whi ch i s both serious and ins tructive .
He s tates tha t a Tatar bow which he tested (pp 25-27 ) was a poor weapon b e cause the range of the arrow whi ch i t shot was only
100 yards ( 90 m) , and concludes that i ts graat -si ze , end tbat of the arrow whi ch i t shot , must have been intended •
intimidate an enemy than to damage him .
more to
However , calculating
the velo city of the arrow from the range , and the energy from the velo city and the we ight of the arrow , i t appears that the arrow had an energy of about 90 J , whi ch i s higher than all but the very highest estimates for the energy of arrows from the mediaeval long-bow.
I t i s thzrefore much more likely
to have been a very dange rous weapon for use at short range , and Pope has been mi sle d by hi s concentration on range .
