Making a Roman Eagle or Aquila
Click on the photos to see an enlarged version
This beautiful Roman artefact is a "Signus Militaris" or Aquila, the standard or flag of Roman soldiers, cast in bronze.
It was found in the area of Salcuta village in Dolj County, about 20 km from the Roman site of Cioroiu Nou.
It is now the property of Oltenia Museum, and will be studied by specialists soon.

After donating to Oltenia Museum the real Golden Aquila, the Roman Eagle standard from ancient times, the Alexis Project decided to make a replica of the Eagle. As a first step, measurements were made of the real bronze Aquila, and good photographs of the original were made.
Lilianan Sipeanu, the Manager of the Cultural House of Scaiesti worked very hard to make an excellent replica of the eagle in clay. The next step is to make a cast of this clay model and put the cast on top of a Roman Flag.

It is then necessary to make a mold of the clay eagle. First, the eagle is supported by heavy steel nails in position, with the nails fixed into a foam block. These nails when removed will provide entry for the liquid casting material when the cast is made later.

The eagle is carefully laid in a suitable plastic container, and a very smooth plaster of paris mixture is poured around and over the eagle, filling the container to the brim.
When the plaster is at least partially set, a thin knife is used to mark the eventual breaks in the mold. The plaster is turned out of the plastic container, and the marks are continued down to the level of the clay eagle from the bottom as well as the top.

When the plaster is completely hard, a rectangular reservoir is carved into the top of the mold, then the mold is broken apart and the nails are removed. The clay is then very carefully completely removed from the inside of the mold, ready for the liquid casting material.

Now we are ready for the casting process. First some lead pipe is melted over the gas stove.

The mold is prepared by first clamping it together, then all the joints are sealed with plaster, leaving the sprues, or holes for allowing lead in and air out, clear.

Lead is poured into the rectangular reservoir on top of the mold, and down the sprues. Then the cast is left to cool down.

The plaster mold is removed, leaving the shiny silver coloured lead cast. Note that the hot lead melted the foam plastic on which the eagle had rested, and formed a cast of that as well.

The cast now stands alone. It remains to remove the sprue casts, as well as the thin flat casts of the gaps in the plaster mold, and clean up the cast.
