Also romanized as *cotyla*.

In ancient Greece, a unit of both liquid and dry capacity, varying with
period and location. For liquids, = 6 *kyathoi*,;
for dry materials, = ¼ *choinix*. About 240 to 300 milliliters.
Hultsch said the Attic *kotyle* was 273.6 mL, which has been generally accepted.

In addition to being a measure, “kotyle” also referred to an actual cup.

The *kotyle* was also said to have a weight of 60 drachms; taking the liquid as water makes the *kotyle* 32 cubic daktyloi.

Lang draws attention to the influence that Greek formulas for the volume of a cylinder, 11/14 times the square of the diameter times the height (from Heron), had on the dimensions of cylindrical standard measures: calculation was easier if the dimensions had 7 as a factor. In the case of the *kotyle*, 3½ *dactyloi* (that is, 7/2) in inner diameter times 3½ in height made 33 11/16 cubic *dactyloi* (by Heron's formula, or 33.67 by ours). The extra cubic *dactyloi* would have been taken up by the “handle” inside the cylinder.

In modern Greece, the royal * kotyle* = 10 liters.

In Egypt, ? – 3^{rd} century ce, a unit of capacity, the Maximian cotyla (κοτύλα Μαξιμιανὰς), between
about 528 and 600 milliliters, according to Mayerson. This is more than 2 times the usual size of the *kotyle*, but close to the size of the Roman *sextarius*. Mayerson speculates that it was a means by which the Egyptians transitioned from the Greek *kotyla* of Ptolemaic days to the Roman *sextarius*.

Cockle's article contains a copy (with translation) of a contract executed on 5 September 264 ce for manufacture of 15,300 pots, the capacity of which is specified in *Maximian kotylai*. (Cockle points out that the size of the *kotyle* given by Segré must be wrong.)

In Archiv f. Papyrusforschung 45.1 (1999), 96-127, we attempt
to demonstrate that from the 4th century A.D. onwards in Egypt the *chous*,
standing as a metrological unit in between the *kotyle* and the *metretes*
(144 *kotylai* = 12 *choes* = 1 *metretes*), disappears
completely from the Greek documents from Egypt (likewise, the *kotyle* and
the *metretes* also disappear).
