hourglass shaped millstones

AbstractThe Eifel massif in West Germany has provided building stone from pre-Roman times to the present day and has been the source of highly-valued millstones throughout the whole of this period. The purpose of this paper is to deal with the production of millstones in this region in particular and to analyse the various forms of millstones and the methods used in their extraction.

The hourglass mills, which may nonetheless be seen within the bakeries at Pompeii, had been comprised of a strong bell-shaped stone over which a hole hourglass formed stone was positioned. The hourglass stone each functioned like a hopper that fed grain into the mill and was additionally turned across the base stone to grind the grain.

Millstones used in Cyprus between the Late Bronze Age and Roman periods (saddle querns, reciprocally operated hopper‐rubber mills, cylindrical rotary querns, and hour‐glass‐shaped Pompeian style mills) were frequently manufactured from igneous …

The millstones were made of lava stone (catillus), material that did not leave harmful residues in flour to the teeth. They had an hourglass shape and long arms of wood, and inside them was inserted a conical element of smaller size (meta). These machines were operated by slaves or donkeys, which imprinted them a rotary motion can grind the grain.

The larger animal or man driven millstones are still are illdefined. As we have previously - noted, it is generally assumed that the large "dome" or "bell-shaped" lower stones, rarely unearthed with their corresponding upper stones, were paired with Pompeian type (hour-glass shaped) upper stones.

Even some Pompeian-style millstones are known in this type of rock (Picavet 2011). For the Eifel area, the production of these hourglass-shaped millstones is also known (Gluhak & Hofmeister 2011; Jaccottey & Longepierre 2011; Hartoch et al. 2015: 32-44). Less diversity is noted in the production of arkosic sandstone, Tertiary puddingstone ...

Details of the complete millstones and those fragments that preserved some kind of shape are given in Table 1; the stone numbers are the same as those on Fig. 2. Three further fragments were found unstratified, either in recent stone dumps above the millstone floor or …

The machinery used to produce bread here consists of millstones, formed from igneous rock, which were turned by mules or donkeys, grinding grains that fell through an hourglass-shaped funnel and through the millstones. It has been suggested that whilst this appears a fairly primitive method, there may been improved techniques in operation ...

The hourglass mills, which can still be seen in the bakeries at Pompeii, were comprised of a solid bell-shaped stone over which a hollow hourglass shaped stone was placed. The hourglass stone both functioned like a hopper that fed grain into the mill and was also turned around the base stone to grind the grain. The worker (human or donkey ...

Rotary millstones hourglass-shaped are also known as Pompeianstyle millstones after the site where they occur so frequently and were first discovered (i.e. Pompeii-Naples; Peacock, 1989;Buffone et al., 2003). Other famous Italian archaeological sites where well-preserved examples have been discovered include Ostia Antica (Rome) and Aquileia ...

Roman rotary grain mills in the Mediterranean area are mainly of two styles: hourglass-shaped "Pompeian-style" mills and flatter, cylindrical millstones. Many of these millstones are made of igneous rocks imported to the sites where the mills are found, and they may therefore be important indicators of resource procurement and trade if the ...

Abstract. The main quarrying area of the Mulargia ignimbrite, used mainly to produce hourglass-shaped millstones during the Roman age, has been identified and sampled in order to update and complete the petrographic and geochemical database by employing standard analytical methods (optical microscopy and ICP-AES/MS spectrometry).

The millstones are made up of a tapered block (meta) fastened to a brick base, around which turned an hourglass-shaped element (catillus), tied with a bar to the mule that forced it to turn. The grain was poured into the catillus and ground as the two blocks rubbed together.

hourglass-shaped upper portion)—one meta (C7; Fig. 2 b) and two catilli (C3 and C6) of rotary millstones of Roman period. The first was found on the acropolis of Cyrene and is still in

Donkeys and horses provided the power, turning the millstones at low rotational speeds. Stones with a steep grinding plane allowed gravity to carry the grain from the inside of the stone, where it was fed in, to the stone's outside edge, where the flour emerged. These hourglass-shaped stones were common throughout the Roman Empire and ranged ...

Millstones used in Cyprus between the Late Bronze Age and Roman periods (saddle querns, reciprocally operated hopper‐rubber mills, cylindrical rotary querns, and hour‐glass‐shaped Pompeian style mills) were frequently manufactured from igneous rocks including vesicular lavas clearly imported to the island. Potential sources include volcanics of mainland Greece, the Aegean, Anatolia ...

There are two main types: the manual round mill and the hourglass grinder, also called the Pompeian type for the significant presence of millstones of this type in the ancient city of Pompeii . The hourglass grinder is comprised of a lower conical stone called a meta and an upper one shaped like an open hourglass, or catillus ( Figure 1 f).

The wheat is ground with large lava millstones, five fine examples of which are seen in the bakery. These are formed by two elements: a lower cone-shaped part (meta) and an upper hourglass-shaped part (catillus). The grain is poured into the catillus that turns when pulled by slaves or animals and grinding the grain and then dropping it below.
