The UCL Institute of Archaeology Air Survey Photographs: an archaeological reference collection of Royal Air Force aerial imagery from 1918–1939

This blog was first featured on the EAMENA blog on September 4, 2017. It is replicated here by the author. The digitised collection is available for browsing through an Album on our Flickr. The collection material is accessible through contact with the UCL Institution of Archaeology Collections Manager Ian Carroll: i.carroll@ucl.ac.uk.

The UCL Institute of Archaeology Collections Air Survey photographs comprise a series of glass plate negatives, cellulose negatives, safety negatives, and prints of Royal Air Force (RAF) aerial photographs taken between 1918 and 1939. The photographs are predominantly of Iraq, the former Transjordan, Egypt, and Sudan (see distribution map). Recently, EAMENA put out a call for information regarding collections of aerial photography. One of the reasons for this is that the aerial photography conducted by the Royal Air Force in the Mandate territories was not comprehensively archived, and some of it was destroyed once it had served its immediate use. What has survived is fragmented, so we are trying to find and piece together those fragments because these images are an amazing resource for discovery, monitoring and analysis of archaeological sites. The UCL collection is one of the larger collections of RAF imagery from the Middle East, and its survival for use in archaeological research was no accident.

This collection originated from a deposit made by O.G.S. Crawford to The British Museum of "obsolete" photographs collected from the RAF during a tour of Iraq, Transjordan, and Egypt in 1928, made at his own expense. In a presentation to the Royal Geographic Society (RGS) and published in The Geographical Journal in 1929, Crawford describes how he enlisted the help of the Air Ministry to photograph sites of archaeological interest, and stated that "these, and also many existing but obsolete negatives abroad, should be handed over to the Director of the British Museum, to form the nucleus of a national collection." The exact contents of this original deposit, however, are not entirely clear from the written record. Crawford stated to the RGS a number of 1,700 negatives; the British Museum Trustee Minutes of 8th June 1929 state 1,150 glass plate negatives and nine rolls of film. This original deposit is likely to be those items now in the UCL Collection, numbered AP1–1356, or possibly all the way to AP1405 (note that there are no items between AP1101–1202 due to misnumbering). As stated, these are predominantly glass plate negatives (most likely gelatin dry plate). It is important to note that many of these are re-photographs of prints or mosaics, which was possibly a mechanism used by the RAF for copying developed material. The original rolls of film have been copied to safety negative film.

Crawford arranged with the Air Ministry for further photography of archaeological sites to be contributed, and the collection continued to grow from these subsequent deposits. The British Museum Trustee Minutes note at least two deposits of this nature: one in 1931 (Trustee Minutes 12th December 1931) and another in 1938 (Trustee Minutes 14th May 1938). These are predominantly 5 x 5 inch cellulose negatives, and some rolls of film (that have been copied to safety negatives). The UCL collection also includes photographs taken as part of Sir Aurel Stein's aerial survey of Iraq with the help of the RAF in 1938 and 1939, so at least one further deposit must have been made, but whether this came from the Air Ministry or from Stein himself has not yet been confirmed. Prints of the majority of this Stein survey material are at The British Academy Archive, though there is some variation in annotation (ASA/3 - see our previous blog, and the Flickr photoset by APAAME). This collection of aerial photographs was originally going to be transferred from the Department of Western Asiatic Antiquities at the British Museum to the Ordnance Survey, where a plan for an aerial photographic library was underway (Trustee's Minutes 12th October 1940, 11th October 1941), but this never came to pass. Instead it was agreed that the collection should be transferred to the Library of the Institute of Archaeology (The National Archives, OS1/384, letter marked '58A', dated 31 May 1949) at Crawford's suggestion (Trustee's Minutes 9 July 1949) to continue as a collection for archaeological reference and something that would be of interest to students. It is now part of the UCL Institute of Archaeology Collections.
Aerial photographs AP816-920, 922-950 of the site of Ur. Background imagery: Google Earth.
The photographs are vertical, oblique, and photo-mosaics. Many of the vertical images comprise series of overlapping photographs. These include such major sites as Ur (AP702–726, 742–886, 888–896, 908–915, 951, 953–955), Mosul (AP451–477), Sulaymaniya (AP678–699), Tell Afar (AP13–27), Erbil (AP319–356), Ctesiphon/Seleukia (AP108–173), Azraq (AP972–1021), Abydos (AP1241–1283), and Giza (AP1615–1622, 1623a).

Photo-mosaics produced from the aerial photography taken by 14 Squadron are particularly common for former Transjordan, including a continuous photo mosaic over four frames of the River Jordan (AP1086–1089), and for the area of Petra and Beidha (AP1286–1289). In only a few instances are the individual frames and the photo mosaic both included in the collection, for example, for Qasr Uweinid (AP1036–1038 and AP1040). This is useful because the creation of a photo-mosaic introduced further distortions into the imagery.

Qasr Uweinid individual frames AP1036-1038 (above), and their mosaic AP1040 (below). Background imagery: Google Earth.

The collection captures some sites in the process of excavation, such as Ur and Khorsobad, and also includes a small number of ground photographs of these two sites (AP645–665 and AP1806–1812, respectively), as well as a single ground shot of Nineveh (AP1805).

The majority of sites captured in Egypt and Sudan follow the Nile, including an extensive collection of photographs of the well-known site of Giza, as well as other pyramids further south. An exception is a small series capturing archaeological sites in the vicinity of the northern section of the Suez Canal and the Sinai Peninsula (AP1591–1614).

This collection was digitised by the APAAME project in 2016 in agreement with the UCL Institute of Archaeology, and in co-operation with the EAMENA project. Where known, images have been geo-located, and this process is on-going. Interestingly, one image, AP357, seems, due to the architectural style visible in the photo, to not be of a site located in the Middle East or North Africa region at all and remains a mystery. Geo-location is assisted by the annotations on the (deteriorating) photograph envelopes; where this type of information was available, this has been included in the image caption on the APAAME Flickr page. These annotations are particularly rich for the original deposit by Crawford, where the majority of glass plates are enclosed in RAF aerial photograph annotated envelopes (or replacement 'Antiquity' or 'Ordnance Survey' stationery), and are secured in wooden glass plate cases.

Only the negatives were digitized. Some interruptions in the sequence of photographs suggest some items are missing, while others have been broken (where possible the latter have been included in the scanning process). There are also prints in the collection, but these have not yet been fully investigated. All enquiries regarding access to the collection and reproduction of the images must be directed to the Collections Manager, Ian Carroll: i.carroll@ucl.ac.uk. We thank Ian Carroll and UCL Institute of Archaeology for their co-operation and assistance during the lengthy digitisation process. Thanks also go to Francesca Hillier (The British Museum Archive), Patricia Usick (The British Museum Egyptian Department), and Angela Grimshaw (The British Museum Middle East Department), who have assisted in our enquiries regarding the provenance of this collection.

The digitised collection can be browsed on the APAAME Flickr page.

Photographs: Deir Ain Abata Project

Dr. Konstantinos Dino Politis has made available to APAAME his collection of slides and negatives taken in the course of aerial reconnaissance in Jordan over a period from the early 1990s until the early 2000s. The collection includes informal photography taken from commercial flights flying in and out of Amman as well as professional aerial photography taken by Dr. Politis and his team from a helicopter in the course of their research. A starring feature of this collection is the site of Deir Ain Abata, a site found and excavated by Dr. Politis.

Deir Ain Abata was discovered during an archaeological survey in 1986 near the modern town of Safi in Jordan, located just east of the southern Dead Sea basin. Under threat from erosion from its location on a steep slope and its vicinity to the expanding town of Safi, it was decided the site would be excavated and conserved. The site consists of a large reservoir, a triple apsed basilica church with mosaics, a cave on the north aisle of the basilica, a refectory, and a 'Pilgrim's Hostel' north of the refectory. 1991 excavations exposed the church, the western front of which was at peril of continuing to collapse down the face of the mountain. Conservation work was undertaken in 1994 to stabilise the structure. An inscription revealed that the basilica had been renovated in 691AD - during the Umayyad period. The cave was presumed by the Byzantine Christians to be associated with the Old Testament story of Lot, though why this cave was chosen over the many others in its vicinity is unknown to us. Evidence in the cave showed that it had been in use since the Middle Bronze Age II.
You can read more about the site in Dr. Politis' article The Monastery of Aghios Lot at Deir 'Ain 'Abata in Jordan here: http://www.hsnes.org/pdf/Lot%20monastery%20article.pdf

Other Dead Sea and Jordan Valley sites feature prominently in the collection- such as Bab edh-Drah, Khirbet Qazone, Tall Numeira, Bethany on-Jordan, Wadi Kharrar and Tell es-Sa'idiyeh. The collection compliments that of AAJ's aerial reconnaissance in that it contains photographs from before AAJ began its annual program in 1997, as well as photographing sites unknown to or visited at other times by AAJ.

The scanning was undertaken on an EPSON Perfection V700 Photo flatbed scanner at 3000 dpi. Due to the age and condition of the slides, results varied - especially in colour output, but unfortunately also in the sharpness of the image. Where possible colour was corrected, and site coordinates and identification, date and photographer identified and placed in the image metadata, but this was not always possible. We have retained any written information from the slides in the image description.

You can find the collection of photographs here: The Konstantinos D Politis Collection
If you have any additional information regarding one of the photographs please do not hesitate to leave a comment on the Flickr photo page. Image requests can be made by contacting Dr. Politis. Copyright is retained by the image photographers.

Slides of Syria

As the year comes to a close, it is inevitable that we reflect on what we have done and what has been happening in the world.

I have been scanning slides from the late 1970s… a lot of slides, of archaeological sites in the Middle East. Most were taken by David K at a time when sites were often in better condition or not yet overgrown by developing villages and towns, so archaeological artefacts in their own right.

While scanning these slides I continually came across evidence of the beautiful archaeological record of Syria, and in the news I daily come across reports of conflict that increasingly and unavoidably is affecting these archaeological sites, whether they are caught in the crossfire or directly targeted by looting.

So, I thought it best to share some of these digitised slides with you and take you to sites that we may not be able to protect now, or visit in the near future, but of which we can hope to preserve evidence and knowledge.

(In no particular order... Please click on an image to enlarge it.)
Basilica, Deir Semaan.
South west church, Deir Semaan.










Deir Semaan (Saint Symeon Monastery or Telanissos) is one of many ruined villages, known collectively as the 'Dead Cities' on the limestone massif west of Aleppo in Syria’s north. These late Roman villages are extraordinarily well preserved, buildings sometimes surviving to two and three stories high, and allowing a superb insight into late Roman town life. These magnificent ruins however have suffered in the crossfire, and also through looting. This short article on the research of Emma Cunliffe, Durham University, includes a witness’s video recording damage to one of these sites, and reports have emerged that the Monastery of Saint Symeon has been damaged by shelling. Link.

Palmyra is one of the best-known ancient sites in Syria. The city flourished due to its profitable position between the west and east, and became a major Roman city in the 2nd and 3rd centuries AD. Built around an oasis in the middle of the desert, the grandeur and preservation of the site is all the more marked due to its isolation, and it has been a favourite of tourists since the 19th century. A report on the Global Heritage Fund blog details how the site has become caught in the crossfire and is a target for looting. http://globalheritagefund.org/onthewire/blog/palmyras_ruins.
West wall of Halebiyeh looking east from the citadel towards the Euphrates River.
Halebiyeh, or Zenobia, is located on the banks of the Euphrates. The walls extending out from the Citadel of an immense Late Roman fortress city are the most prominent feature of this beautifully preserved site. The astonishing scale and quality of preservation can be gauged by noting David’s white LWB Landover (inside of the city wall in the centre of picture) (cf. D. L. Kennedy and D. N. Riley, Rome’s Desert Frontier from the Air, London (Batsford)).

Section C3 of Dura Europos.
Palmyra gate, Dura Europos.










Dura Europos, also on the banks of the Euphrates River, was preserved in sand until its excavation during the interwar period, prompted by the discovery of remarkably preserved frescos. Even more important was the discovery of a huge cache of papyri which included the largest single collection of papyri for the Roman army anywhere in the Empire, including Egypt.
The Tetrapylon at Damascus, located at one end of Souk al-Hamidiyeh to the west of the Umayyad Mosque in the city centre.
Damascus is the ancient and modern capital of the region and where the archaeological record is hidden in side streets, built into houses, and walked through as part of daily life in a thriving city. As fighting intensifies closer to the ancient city (BBC news article: http://www.bbc.co.uk/news/magazine-20659573) how will the ancient walled city and 1400 year old Umayyad Mosque built over the immense church of St John fare if it breaks through to the heart? The once lively Souks and are now devoid of tourists and suffer from intensifying security raids. One hopes the beautiful Souk al-Hamidiyeh and the numerous early medieval houses tucked in side streets will not suffer the same fate as the ancient heritage listed market place of the city of Aleppo, the Souk al-Madina, which was irreparably damaged in September– see http://www.reuters.com/article/2012/09/30/us-syria-crisis-idUSBRE88J0X720120930
General view (north) of Bostra.
Bostra is in the south of Syria in a region known as the Hauran – a fertile semi-arid landscape on the edge of ancient lava-flows. It was the northern-most city of the Nabataean kingdom that stretched down through its capital at Petra into north-western Saudi Arabia. Nabataea was incorporated into the Roman Empire with Bostra as the capital of the new province of Arabia under Trajan in AD 106. The site is perhaps best known for its Roman theatre built from black basalt rock, but the ruins of the ancient city are also well preserved amongst the streets of the modern town, with towers in some cases standing over two stories high. The town has been damaged by shelling this year.

I would like to thank David for looking over this blog, and for his continual remarks and encouragement while I develop the APAAME digital collection. Any remaining errors are wholly my own.

Digitising our Collection - Slides

The Aerial Archaeology in Jordan project has been in action since 1997, but before that David Kennedy was visiting sites in the Near East for his own enjoyment and research. Most of the images he took on the ground were processed into slides.

Slides are a thing of the past, and not the best way to store your negatives, and it is now one of our projects to digitise this collection and add it to our online archive.

The slides I have been starting on are photographs from Syria, taken in the 1970s, and have not been stored in optimal conditions. The 35mm negatives are mounted between thin glass within a slide frame, and then stored in slide sheets in a filing cabinet. Most slides have developed a sticky, oily residue from the interaction with non-archival plastic slide sheets, small spots of mildew have started to appear on the slides, and the colour of the slides has started to degrade, developing a magenta tinge. In some cases, the glass mounting has shattered, scratching the negative.

A preliminary cleaning of the slides to remove what we could of the oily residue could not clean the frame well enough to remove all traces of the residue, and this did not tackle the minor mildew problems. With advice from the State Library of WA Conservator, we will be using a 50:50 solution of Ethanol Absolute and Deionised Distilled Water to clean the slide frames and glass mounting. This same solution can be applied carefully to those negatives that have been effected by mildew - but we must be careful not to let the solution interact with the emulsion side which could cause permanent damage to the slide. The ethanol solution will evaporate quickly and leaves no residue.

Once the slides have been cleaned and scanned - we hope that we will be able to edit the images individually to correct any permanent scars such as scratches, or any traces of dust that may have come through during the scanning process. Colour correction will be used to minimise the effects of the magenta tinge.

We shall let you know of our progress. Any advice is most welcome.
