Ewer signed by Yunus ibn Yusuf al-Mawsili

A brass ewer hammered and inlaid with silver and gold, signed and dated by its maker, Yunus ibn Yusuf al-naqqash al-Mawsili, to 644 AH, 1246-47 CE. Its body carries the standard courtly repertoire of Jaziran luxury metalwork, hunters, musicians and an enthroned ruler, beneath a benedictory inscription to an unnamed sultan. Nothing else is known of Yunus ibn Yusuf beyond this one signature.

It surfaced in the Istanbul art market in the 1910s, reportedly from the collection of a former Ottoman Grand Vizier, and was bought from the dealer Dikran Kelekian by Henry Walters in 1917. It entered the Walters Art Museum through Walters' 1931 bequest of his entire collection to the City of Baltimore; the accession number it carries, 54.456, is an internal classification, not a year, and should not be read as one.

It belongs to the same broad group of al-Mawsili-signed metalwork as the British Museum's Blacas Ewer, made fourteen years earlier, but the two share only a toponymic professional name, not a documented workshop link; and it has no connection at all to the Hermitage's Bobrinski Bucket, a Herat object from an unrelated tradition eighty-three years older. Whether the wider al-Mawsili group represents one continuous Mosul workshop tradition or several independently trained craftsmen who shared a point of origin and a reputation remains an open question in the scholarship, and this ewer's single, workshop-less signature sits at the center of that question rather than resolving it.

What it is

A tall brass ewer, 44.5 centimetres high, hammered and raised into a faceted body with a flaring neck, then chased and engraved and inlaid with cut silver and gold against a ground darkened with a black organic resin so the metal inlay reads clearly against it. It is a water vessel built for a courtly household, not a devotional or funerary object, and its decoration is arranged in registers and medallions running around the neck and body in the standard format of Jaziran inlaid brass of its period.

What sets it apart from the great majority of objects in this class is a single detail cut into the metal at the base of the neck: a name, a trade description and a date. Most Islamic metalwork of this era carries no maker's name at all. This one does, and that is the reason it has a page in this archive rather than sitting anonymously among the hundreds of comparable undated brasses in museum storerooms.

How it was made

The body was raised from a single sheet of brass by hammering, then finished on a series of separate campaigns: chasing and engraving to cut the outlines of the inscription bands and figural medallions, followed by the inlay itself, silver and gold sheet and wire cut to shape and hammered into undercut channels, and finally a black resinous compound rubbed into the engraved ground around the inlay to darken it and throw the metal into contrast. This is the standard construction sequence for inlaid Mosul-tradition brass of the twelfth and thirteenth centuries, not a technique unique to this piece.

The combination of silver and gold inlay on the same vessel is worth noting in passing, since a considerable amount of surviving Jaziran brass of this date uses silver alone; where a source can be checked for the specific metals used on a given object, gold tends to be reserved for smaller accents rather than whole fields, and that appears to be the case here as well, though this record has not been able to confirm from the sources consulted exactly which elements of the decoration carry gold as against silver.

The signature

The inscription names the maker as Yunus ibn Yusuf and gives him the professional title al-naqqash, meaning the engraver or the decorator, the craftsman responsible for cutting and inlaying the ornament rather than necessarily the one who raised the brass body itself. He closes his name with the nisba al-Mawsili, of Mosul, tying his training or his working identity to that city, then the leading center of inlaid brass production in the Jazira.

Medieval Islamic artisans overwhelmingly worked anonymously. A signed, precisely dated object naming both a craftsman and his trade is therefore a documentary event in its own right, independent of the quality of the object it appears on, and it is the single fact this record can state about Yunus ibn Yusuf with total confidence.

The decoration program

The body carries a sequence of scalloped medallions set against a fretwork or vegetal ground, enclosing figural scenes: hunters mounted on horseback, musicians seated beneath a tree, and an enthroned ruler attended by figures around him. This is the standard courtly repertoire of thirteenth-century Jaziran inlaid metalwork, sometimes described in the wider literature on Ayyubid and Zangid luxury objects as a cycle of princely pleasures, hunting, music and audience together standing for the ordinary business of rulership rather than illustrating any specific narrative or text. That general framing is well established for this class of object; this record has not located a source that reads the specific medallions on this ewer as anything beyond that conventional courtly vocabulary, and no source consulted proposes a narrative subject, a named ruler portrait, or a text the imagery illustrates.

Running with the figural bands is the benedictory inscription addressed to an unnamed sultan. Dedicatory formulas of this kind were a standard feature of luxury metalwork made for or offered to a court, functioning as a generalized wish for the dominion, glory and long life of whoever received the object, whether or not that person is named elsewhere on the piece. Here, no personal name for the honorand survives in the material available to this record, which is recorded as an open question rather than filled with a guess.

The Mosul school, and what is actually settled about it

Modern scholarship groups a body of signed and dated inlaid brass from this period under the label Mosul school, after the city named in enough of the surviving signatures to make the association plausible. The evidentiary base is a set of signed objects spanning roughly the 1220s to the 1280s, several dated and several naming Mosul or the nisba al-Mawsili explicitly. A widely cited count places the number at 27 of 35 signed pieces of this broader corpus carrying the nisba al-Mawsili, with 8 of those 27 giving some further identifying detail beyond the toponymic alone.

What is not settled, and is a live methodological argument rather than a footnote, is whether that shared nisba is evidence of one continuous workshop tradition, in the sense of masters training pupils within a persisting Mosul-based lineage, or whether it instead records a wider and looser phenomenon: individually trained craftsmen who had passed through Mosul at some point, or simply advertised the city's reputation, and who otherwise worked independently, in different cities and different decades, for different patrons. Julian Raby's 2012 essay 'The Principle of Parsimony and the Problem of the Mosul School of Metalwork' takes up exactly this question, re-examining the corpus of signed pieces rather than accepting the school as a single settled unit; this record was able to confirm the essay's existence, title, venue and its general argument through reviews and library records, but was not able to read its full text directly, and its detailed reasoning is flagged here for verification against the original rather than restated as read. What can be said without that caveat is that the underlying uncertainty is real: a shared professional name proves shared origin or training far more securely than it proves a single ongoing workshop.

The historical context that makes this argument matter is the Mongol capture of Baghdad in 1258 and the subsequent pressure on Mosul itself, which scattered Jaziran-trained metalworkers into Syria and Egypt over the following decades, carrying the inlay technique and, in some cases, the nisba al-Mawsili with them long after they had left the city. Yunus ibn Yusuf's ewer, dated 1246-47, was made before that dispersal, in what turned out to be the last full generation of Jaziran production before the disruption. Whether he himself worked in Mosul, or elsewhere in the Jazira while still carrying the nisba, is not established by the object alone.

Distinguishing this ewer from the Blacas Ewer and the Bobrinski Bucket

This corpus already holds two other named, dated pieces of medieval inlaid metalwork, and neither should be confused with this one or with each other. The Blacas Ewer, now in the British Museum, is signed by Shuja ibn Man'a al-Mawsili and dated Rajab 629 AH, April or May 1232, fourteen years before this ewer and, so far as the object's own inscription goes, also made at Mosul. It is a different physical object in a different collection, and no source consulted for this record documents any personal or workshop connection between Shuja ibn Man'a and Yunus ibn Yusuf beyond the shared nisba al-Mawsili itself.

The Bobrinski Bucket, in the State Hermitage Museum, belongs to an entirely separate tradition and is not connected to either Mosul ewer by any named maker. Its own inscription dates it to Muharram 559 AH, December 1163, eighty-three years before this ewer, and names two different craftsmen: Muhammad ibn Abd al-Wahid, who cast it, and Mas'ud ibn Ahmad, who executed its silver and copper inlay. It was made in Herat, in present-day Afghanistan, some two thousand kilometres east of Mosul, and belongs to the Khurasan school of inlaid metalwork, a separately argued regional tradition; neither of its named craftsmen carries the nisba al-Mawsili, and nothing connects them to Yunus ibn Yusuf, to Shuja ibn Man'a, or to Mosul at all.

What links this ewer to the Blacas Ewer, and to a wider group of roughly two dozen other signed pieces, is the shared toponymic nisba al-Mawsili and, more loosely, a shared decorative vocabulary and construction technique current across the Jazira in this period. That is a real and citable connection. It is not the same claim as a documented master-apprentice relationship or a single continuous workshop, and this record does not make that stronger claim for Yunus ibn Yusuf, because no source consulted supports it.

Ownership across seven centuries: the long gap

Between the ewer's manufacture in 1246-47 and its documented appearance in the international art trade by the early twentieth century, no owner, location or transaction is recorded in any source consulted for this record. That is a gap of roughly six and a half centuries, and it is recorded here as a gap rather than bridged with a plausible-sounding guess about an Ottoman treasury, a Mamluk collection, or a private household, none of which this record can support with a source.

The ex-Grand Vizier and the Istanbul art market

The first point at which this ewer's ownership becomes documented, even partially, is through the dealer Dikran Kelekian's own account. Writing to Henry Walters around 1917 to encourage the purchase, Kelekian stated that he had bought the piece in Istanbul from a former Ottoman Grand Vizier, whom he described as having owned nearly all of a group of inlaid bronzes also acquired at various points by a Baron and by the American collector and Tiffany & Co. designer Edward C. Moore. This record was able to locate this account only through a secondary academic source quoting Kelekian's correspondence, itself accessed through search-indexed text rather than a directly readable full copy, and the transcription available to this record is imperfect: the Baron's name renders inconsistently across the copies located, and should be checked against the original letter, which is understood to be held among the Walters Art Museum's own curatorial or archival files.

One Ottoman statesman fits the description of a former Grand Vizier active in the relevant period: Gazi Ahmed Muhtar Pasha, who held the office of Grand Vizier in 1912. This record has not been able to confirm that he is the individual Kelekian meant, and treats the identification as a plausible but unverified inference rather than a documented fact.

Kelekian, Walters, and the art market of the 1910s

Dikran Garabed Kelekian, an Armenian dealer born in 1868, established an antiquities business in Istanbul with his brother Kevork around 1892 and went on to open galleries in New York, Paris, London and Cairo, dealing across Coptic, Islamic and classical material. He is documented as having played a substantial role in forming Henry Walters' Coptic, Early Christian and classical holdings, in addition to this piece, and served a client list that also included George Blumenthal of the Metropolitan Museum. He died in New York in January 1951.

Henry Walters bought the ewer from Kelekian in 1917 for his private Baltimore collection, one of a great many Islamic and late-antique metal vessels he acquired through Kelekian and other dealers across roughly three decades of collecting.

Entering the museum: 1917 to 1931

Henry Walters died on 30 November 1931, leaving his entire collection, roughly twenty-two to twenty-four thousand objects depending on the count used, together with the gallery building and an endowment, to the Mayor and City Council of Baltimore for the benefit of the public. The Walters Art Gallery, later the Walters Art Museum, opened to the public as an institution in November 1934, after the Maryland General Assembly incorporated its Trustees in 1933.

The Walters accession number carried by this object, 54.456, is not a year and should not be read as one. The museum's own online catalogue lists other ewers acquired by Henry Walters in different years, including one purchased in 1913 and one in 1929, that carry the same 54-prefixed classification series; the prefix identifies a type or department grouping internal to the Walters' own numbering system, not the year of acquisition. This record notes the correction because the resemblance between '54.456' and a mid-twentieth-century date is an easy and understandable misreading.

What is unresolved, and what is not

No source consulted for this record documents a theft, a wartime loss, an export dispute, or a restitution claim involving this ewer. It left Ottoman territory through an ordinary private sale between a dealer and a private American collector in 1917, decades before the 1970 UNESCO Convention on the means of prohibiting illicit transfer of cultural property, and before the modern state of Iraq, formed from former Ottoman provinces including Mosul in 1921, had any export-control regime of its own to be triggered. That absence of any recorded legal complication is itself a finding, not an oversight in this record's research.

What remains genuinely open is narrower and is recorded in full in the questions below: the identity of the sultan addressed in the benedictory inscription, the ewer's whereabouts for six and a half centuries, the precise identity of the ex-Grand Vizier who sold it into the trade, whether the vessel is complete or has lost or gained elements over time, and where Yunus ibn Yusuf himself sits, or does not sit, in relation to the other named al-Mawsili craftsmen.
