Gold and silver on indigo: a late-Heian sutra volume and its lacquered storage at Cleveland

Cleveland holds two registers of late-Heian sumptuous-sutra production. Accession 1916.1060 is a single twelfth-century handscroll fragment of the Abhidharmakośa-bhāṣya, written in gold and silver ink on indigo-dyed paper. Accession 1969.130 is the other half of the apparatus: a lacquered wooden repository made for a Daihannya-kyō dedication, with eleven surviving companion handscrolls in gold ink on dyed paper. Together they record the text-and-container infrastructure of the twelfth-century aristocratic merit-copying programme.

What the indigo paper carries

The surviving handscroll is 26.4 cm tall and 670.6 cm long — a 6.7-metre fragment, not a single sheet, identified by the Cleveland catalog as the seventeenth section of the thirty-part Xuanzang translation of Vasubandhu’s Abhidharmakośa-bhāṣya. The first thing the scroll does, as the unrolling begins, is colour: a deep, dense blue that fills the field before the text resolves.

The ground is paper, dyed with ai (藍, Persicaria tinctoria, Japanese indigo) in the standard late-Heian process: multiple immersion baths in fermented indigo vat, alternated with rinsing and partial drying, until the fibre is saturated to a colour that reads almost black at low light and reveals its blue under sunlight or museum lamp. The result is a paper that was meant to read at two distances: from across a room, a dark uniform field; in the hand, a saturated blue that catches and holds the viewer at column-by-column reading distance.¹

Across that ground the text columns are ruled in faint lines and filled with vertical sutra-script characters in two metallic inks. Gold (kondei, 金泥) carries the principal text: the canonical run of the Abhidharmakośa-bhāṣya in Xuanzang’s translation. Silver (gindei, 銀泥) carries the secondary register, which may be chapter divisions, marginal annotations, or alternating column blocks, depending on the local convention of the scriptorium that produced the volume. The combined gold-and-silver-on-indigo programme is the high-prestige variant of the type; the more common late-Heian sumptuous-sutra programme uses gold alone (konkonji-kyō, 紺紙金字経, ‘indigo-paper gold-character sutra’), with silver reserved for the more elaborate court-and-temple commissions.²

Two technical points organize the surface. The pigments are not paint in the western sense; they are metallic powders (gold leaf and silver leaf, ground in animal-glue binder and applied with a brush) that sit on the paper rather than penetrating it. This is why the characters retain their crispness across nine hundred years: the metal is held at the surface and has not bled into the indigo ground.

The second point follows from the first. Silver oxidizes; gold does not. On most surviving gold-and-silver-on-indigo sheets, the silver characters have darkened to a near-black or grey-brown that no longer reads clearly against the indigo, while the gold characters stand out in their original brightness. The extent of silver tarnishing on Cleveland 1916.1060 cannot be confirmed from the catalog page’s published image alone, but the conservation expectation is set by the type.³

What the published image does not resolve at the museum’s strip-thumbnail crop is the frontispiece. The canonical late-Heian sumptuous sutra opens with a mikaeshi (見返し, ‘looking-back’, the inside-back of the protective cover that becomes the inside-front when the scroll is unrolled): a figural painting in gold and silver line on the same indigo ground, depicting the sutra’s principal narrative or doctrinal program.

For the Lotus Sutra, the mikaeshi typically depicts a chapter scene: Śākyamuni preaching on Vulture Peak, the Burning House parable, the Bodhisattva Avalokiteśvara delivering beings from peril. For the Abhidharmakośa, a philosophical commentary without a narrative arc, the mikaeshi convention is harder to predict; whether this surviving fascicle preserves a frontispiece, and what it depicts if so, is not visible at the published resolution and not stated in the catalog text.

What the standing repository carries

The companion piece is a different object class and a different problem. Cleveland accession 1969.130 is not a flat sutra box but a tall standing shrine-style repository (kyō-zushi register, 経厨子 / 経蔵 reading): 160 cm in overall height, with a domed-finial lid over a cylindrical body, swing-out front doors, and a tiered octagonal base.

The catalog identifies it as one of an originally-paired set; the second repository is lost. Cleveland holds the surviving repository plus eleven companion sutra-volume handscrolls from the dedication. The repository alone is separately accessioned as 1969.130.1; the individual sutra volumes are 1969.130.2.a through .l (or whichever sub-suffix the museum has assigned to the surviving eleven).

One representative volume, 1969.130.2.d (“Volume from the Great Perfection of Wisdom Sutra”), is recorded as a handscroll in ink and gold on dyed paper, the more common gold-only register of the type rather than the gold-and-silver of 1916.1060.⁴

The repository is the kind of object that organizes how one thinks about the sutra-copying programme. The Daihannya-kyō in the canonical Xuanzang translation runs to six hundred fascicles, the longest single text in the East Asian Buddhist canon and the standard scripture for issaikyō-class merit-copying programmes (一切経, ‘all the sutras’, the complete tripiṭaka).⁵

A complete copying programme produced six hundred handscrolls, each rolled around a wooden core with bone or lacquer end-knobs, and each bound between paired protective covers. To house six hundred volumes a single repository is insufficient; the canonical solution was paired storage at temple scale, and the surviving Cleveland repository is the surviving half of one such pair. The lost mate would have held the other portion of the set.

What is on the doors and back panel is the iconographic argument the object actually makes. The Cleveland catalog records both halves clearly.

On the doors: “Eight of the 16 benevolent but fierce looking deities who protect the text appear on the doors.” These are the Jūroku Zenjin (十六善神, ‘sixteen good gods’), the canonical guardian retinue of the Mahāprajñāpāramitā-sūtra in the East Asian Buddhist tradition. Each door panel of the Cleveland repository carries four protectors — eight in total, a half-set — and the lost mate-repository would have carried the other eight. The visual programme is the standard Daihannya tenmae (大般若転読, ritual recitation of the prajñāpāramitā) protective iconography.

On the back panel: “Two discs painted on the back have the sacred syllables representing the Buddha Shakyamuni and the Buddha Amida.” These are bīja (種字, shuji), Sanskrit seed-syllables encoding the deity in a single graph. Shakyamuni and Amida, paired, place the dedication doctrinally between historical-Buddha veneration and Pure Land aspiration: a hybrid configuration that is plausible for a late-twelfth-century commission contemporary with the Hōnen-Shinran formative period but pre-Jōdo-shū institutional consolidation.

The medium specification on Cleveland 1969.130 spells out the canonical Heian sumptuous-lacquer programme: black or red urushi ground (urushi, 漆), painted figural and floral decoration in ink and pigment, applied gold pigment and gold leaf, kirikane (截金, cut-gold linear ornament applied as fine strips of beaten gold leaf), and gilt-bronze metalwork (typically corner mounts, lockplates, and hinges).

On a 160-cm standing repository this surface programme is substantially larger than a small-format kyōbako would carry: the painted figural panels on the inside of the doors (each roughly 60–80 cm tall in proportion) become themselves devotional pictures rather than decorative ornament, and the seed-syllable discs on the back panel function liturgically as the focus of a closed-door reverence. The combination is a register one or two below the maki-e (蒔絵, sprinkled-metal-powder lacquer) cabinetry that the highest-prestige Heian aristocratic commissions used, but it sits comfortably within the upper tier of twelfth-century ritual-object production.⁶

What the eleven surviving volumes register is a programmatic survival in fragment. A late-twelfth-century Daihannya-kyō dedication produced six hundred volumes; eleven survive in Cleveland’s holding, kept with the surviving repository half. The other five hundred and eighty-nine volumes are dispersed, lost, or held elsewhere under separate accession numbers and untraced provenance — and the paired-mate repository has not been located in published institutional records.

The Cleveland eleven are an instructive small sample: enough to confirm that the dedication used the canonical Xuanzang text in gold-on-dyed-paper format, with the repository in the matching lacquer programme, but not enough to reconstruct the dedication’s commissioning patron, its temple destination, or its date within the late twelfth century beyond what the repository’s lacquer style and the Shakyamuni-Amida bīja pairing support. Tracking the lost mate-repository through other museum or temple holdings, if it survives, would substantially tighten the picture.

The institutional ground: aristocratic merit-copying programmes

The class of object both Cleveland accessions belong to is the dedicated sutra copy (hōkō-shakyō, 奉行写経, or more loosely kuyō-kyō, 供養経): a sutra produced not for everyday liturgical use but as the material vehicle of a merit-transfer dedication, commissioned by an aristocratic patron for a specific religious purpose and presented to a temple as the tangible offering.⁷ By the late Heian period, two principal dedication motives had stabilized.

The first was tsuizen-kuyō (追善供養, posthumous merit-transfer): a dedication for the benefit of a deceased family member, typically a parent, a spouse, or a child, in which the merit accrued by commissioning and producing the sutra was formally transferred to the deceased to assist their rebirth into a favorable destination. Genshin’s Ōjōyōshū (985) had codified the deathbed-and-postmortem ritual programme that aristocratic Heian families followed; commissioning a dedicated sutra in the year following a death was one of the standard merit-acts a senior family would undertake, alongside building or endowing a memorial chapel.⁸

The second was hōkō (奉行): a dedication on behalf of the living, often the patron themselves, intended to accumulate merit during the patron’s lifetime to ensure favorable conditions in the present life and a favorable rebirth. Both Fujiwara no Michinaga’s Hōjō-ji programme (1020) and Fujiwara no Kiyohira’s Chūson-ji issaikyō (begun 1117) belong to this class: a sustained, multi-decade commissioning programme in which the patron systematically produced sumptuous sutra copies as part of a broader Pure Land merit-construction programme tied to the patron’s own posthumous trajectory.⁹

The Cleveland materials sit somewhere within this dedication framework, but the specific patron, temple, and date for either accession have not been published. The 1969.130 Daihannya-kyō dedication is the clearer case in class terms: an issaikyō-tier commission of a six-hundred-fascicle text plus a matching prestige repository is a substantial undertaking, plausibly Fujiwara-network or senior-temple-affiliated, plausibly tied to a sustained merit-construction programme rather than a single posthumous offering.

The 1916.1060 Abhidharmakośa fragment is harder to place. The text is a doctrinal commentary central to the Hossō and Kusha schools rather than a Pure Land devotional text, and a sumptuous gold-and-silver copy of it is more plausibly tied to a Nara-temple or Hossō-affiliated commission than to a Fujiwara Pure Land programme. The published Cleveland record does not tighten the attribution.

Reading against the canonical comparanda

Two large-scale dated comparanda anchor the surviving Heian sumptuous-sutra corpus. Both are unavoidable when reading any unattributed twelfth-century gold-on-indigo fragment.

Chūson-ji (中尊寺) at Hiraizumi in Iwate Prefecture holds the principal surviving Heian issaikyō programme. Fujiwara no Kiyohira (1056–1128) commissioned a complete tripiṭaka in gold-on-indigo format from 1117, intending the set as the textual centerpiece of his northern political-and-religious complex; his son Motohira and grandson Hidehira continued the commission through the twelfth century, expanding the set into the thousands of fascicles. A substantial portion survives at Chūson-ji’s Konjiki-dō (金色堂) treasury and at affiliated institutions, designated National Treasure and the canonical reference point for any Heian gold-on-indigo sutra dating.¹⁰

The Chūson-ji set is overwhelmingly gold-only (konkonji-kyō); the gold-and-silver alternating-column variant is rarer in the set and reserved for higher-prestige presentation copies within the larger commission. The Cleveland 1916.1060 gold-and-silver register places it on the higher-prestige side of the type, though not necessarily within the Chūson-ji programme itself.

Itsukushima Shrine at Hatsukaichi in Hiroshima Prefecture holds the Heike Nōkyō (平家納経), the thirty-three-scroll Lotus Sutra dedication commissioned by Taira no Kiyomori (1118–1181) and his Heike-clan family members in 1164. Each of the thirty-three scrolls was assigned to a different Heike family member as commissioner, and each was produced by a different team of calligraphers, painters, and metalworkers, yielding a set in which no two scrolls follow the same visual programme.

The combined apparatus (gold and silver pigments, applied gold and silver leaf, kirikane, figural mikaeshi, gilt-bronze fittings, brocade covers) is the apex case of the late-Heian sumptuous-sutra dedication class.¹¹ The Heike Nōkyō is a calibration object: nothing in the surviving Heian corpus surpasses it in finish, and any twelfth-century sumptuous-sutra fragment is read against its register.

The Cleveland 1916.1060 fragment cannot be placed within either programme on the published evidence. It is twelfth-century, it is gold-and-silver-on-indigo, it carries the Abhidharmakośa-bhāṣya text, and the Worcester R. Warner Collection bequest in 1916 is its earliest documented owner. Pre-1916 provenance (the temple of origin, the patron, the dispersal route into the late-nineteenth or early-twentieth-century international market) is not in the published record.

The text itself argues against a Pure Land aristocratic commission: the Abhidharmakośa is a Hossō-school doctrinal text, more plausibly tied to a Nara temple commission than to a Heike or Fujiwara Pure Land programme. The 1969.130 Daihannya-kyō dedication is on the other side of the textual line, in standard issaikyō-class Mahāyāna scripture, but its lacquer repository’s late-twelfth-century date and high-prestige finish are equally unattributed.

What the photographs cannot resolve

Both Cleveland accessions sit in storage. The catalog records list both as not currently on view; high-resolution Cleveland-Open-Access imagery is the principal access route for a researcher today. That access has limits the printed record makes plain.

For 1916.1060, the published image resolves the column ground, the gold characters, and the indigo paper at a register sufficient to read the text technique. What it does not resolve is the silver oxidation extent (whether the silver register is still differentially legible against the gold or has darkened to near-uniform grey-brown), the paper’s surface texture (whether the indigo-dyeing has the characteristic uneven mottling of late-Heian ai-vat work or the more uniform machine-like dyeing of later Edo restorations), the column-ruling technique (whether ruled in gold on the indigo ground, in silver, or in a fugitive third pigment), and the original cover apparatus (the wooden core, the cover materials, the protective wrapper, all of which are unrecorded in the catalog).

For 1969.130, the parent record image (the open-doors-with-volumes-laid-out composite reproduced above) resolves the repository’s overall form, the doors-and-back iconographic programme at the level of identifying figural panels and bīja discs, and the eleven companion volumes’ indigo-cord-tied register.

What it does not resolve is the specific identification of which eight of the sixteen Jūroku Zenjin are present (the catalog says eight without naming them; the named-protector identifications would require either Cleveland’s internal documentation or operator examination at higher resolution), the precise kirikane patterning, the maki-e-or-not status of the gold areas (whether sprinkled-powder or applied-leaf or painted pigment), the metalwork’s alloy composition, or the back-panel bīja in their specific Siddhaṃ forms (the catalog gives the deity-identification, not the specific seed-syllable graphs used).

The eleven companion volumes are imaged in the same composite; the published reproduction does not separately resolve the mikaeshi, the cover apparatus, or any dedication colophon at the head or tail of an individual scroll.

The honest reading. The Cleveland materials are good evidence for the type-class and reasonable evidence for the late-twelfth-century dating window. They are not, on the published evidence, sufficient to attribute either accession to a specific dedication, commissioning patron, temple of origin, or workshop.

The 1969.130 repository’s Shakyamuni-Amida bīja pairing and Jūroku Zenjin doors give the object a specific iconographic identity that future research can build from; the 1916.1060 fragment’s identification as fascicle 17 of 30 in the Xuanzang Abhidharmakośa-bhāṣya translation similarly gives a textual specificity that any future search of Heian sutra-fragment holdings can use to test for matched fascicles in other collections.

Closing the broader attribution gap would require a Cleveland conservation report (technical analysis of the indigo-dye chemistry, the gold-and-silver pigment alloys, and the urushi composition), a search of the Worcester R. Warner Collection’s pre-1916 acquisition records, location of the lost paired-mate repository for 1969.130, and a comparative-style analysis against the dated comparanda at Chūson-ji, Itsukushima, and the better-documented late-Heian sutra-fragment holdings at Tōkyō National Museum, Nara National Museum, and the Kyoto National Museum. None of that work is in the published English-language record as of the access date.

What the materials do support, without the attribution apparatus, is a clearer view of the late-Heian sumptuous-sutra production system in its institutional shape: the indigo-paper-and-metallic-ink text technique on one side, the lacquered prestige-repository cabinetry on the other, both tied into the aristocratic and temple commissioning programmes that produced the canonical twelfth-century corpus. Cleveland 1916.1060 and 1969.130 are two pieces of that apparatus in a North American holding, and they read better together than either does alone.
