Dating a Brick Gate: Sebka, a Coin, and a Council's Branding
A town council in Córdoba province is restoring a fragmentary brick gate and wants a period label for EU funding. Surviving elements: a horseshoe arch with alfiz; a panel of sebka above the arch; stone imposts; no muqarnas; no epigraphic band; a small ribbed dome inside. A foundation trench produced a coin minted between 1195 and 1212, sealed below the first course. A later repair contains carved yesería in a Nasrid manner. One consultant dates the gate to the Almohad period (late 12th–early 13th century); another argues for the Nasrid period (14th century) because of the sebka. The council prefers 'Almohad' for its tourist branding. There is no money for excavation and the report is due in three weeks. You must separate construction phases, rank the evidence, and avoid overclaiming.
1. Rank the evidence and decide whether the gate should be labelled Almohad or Nasrid. Show your reasoning.

The original gate is best labelled Almohad, 13th century, with a later Nasrid or Mudéjar repair - but with a qualifier.
- Sealed coin of 1195–1212 below the first course (strongest): a terminus post quem. The gate cannot have been built before 1212, which rules out an early Almohad date but not a later Almohad or a Nasrid one.
- Structural typology - brick, horseshoe arch, alfiz, ribbed dome (moderate): compatible with Almohad practice and with later Mudéjar/Nasrid work; not exclusive.
- Sebka (weak for dating): it originated under the Almohads and continued under the Nasrids. The second consultant is treating a long-lived ornament as a period marker.
- Absence of muqarnas and epigraphic band (weak): negative evidence is unreliable in a fragmentary gate; such elements may have been lost.
- Yesería repair (separate phase): it dates a later intervention, not the original construction.
The coin plus the structural package supports a 13th-century Almohad phase. The sebka does not justify a 14th-century date. The report should distinguish original fabric, later repair and modern restoration.
2. Write an 80-word panel for the EU funding application that separates phases and avoids overclaiming.

Draft: 'The gate was built after 1212, when a coin of 1195–1212 was sealed beneath its first course. Its brickwork, horseshoe arch, alfiz and ribbed dome fit Almohad practice of the 13th century. The sebka panel is not a Nasrid signature: it originated under the Almohads and continued later. Carved yesería belongs to a later repair. We therefore present an Almohad gate with a Nasrid/Mudéjar phase, and avoid dating it by ornament alone.'
The text names the decisive evidence, gives a date range rather than a false precision, separates the phases, and corrects the consultant's reasoning without personalising the dispute. It also protects the council: if a future excavation revises the date, the panel has already stated the basis for the current interpretation.
3. What single piece of evidence would most change your dating, and why?
Read the worked answer
A securely dated foundation inscription or a radiocarbon date from a sealed mortar sample taken from the original core of the gate would change the dating more than any further stylistic comparison. The coin gives only a terminus post quem; an inscription or a dated mortar sample would give a direct construction date, or at least a tighter bracket. Excavation of the foundation with stratified ceramics would do the same. A documentary reference to the gate's construction, or a dated parallel in a nearby building with an intact foundation, would also help. By contrast, more examples of sebka would not settle the question, because the motif spans both periods. The point is to replace a stylistic argument with an independent chronological control.
