Cartouches

Here are pictures of various cartouches I took during a recent trip to Egypt. Some of them can be identified unambiguously. Other are challenging, at least for me. Comments and suggestions are welcome. Let's start with an easy one from Kom Ombo.



Ptolemy, beloved by Ptah, forever alive.

The next one is easy too.

Psamtik

Here come a few from the spectacular and rarely visited Kerma museum .


Taharka


Taharka(praenomen): Khau Nefertamra



Tanutamani


Tanutamani(praenomen): Bakara

A good one from the Aswan Museum on Elephantine Island.



Left:Ibkhara (the heart of Ra rejoyces) setepenamon (chosen by amon). Right: Alexandros(!)

Now some challenge:


a. wnnefer kheper? Form of Oiris? ? Tiberius??


b. Left: Kysars (Caesar, so it's a Roman emperor) Right: heramys (Germanicus->Caligula?)


c. Awysrs (Kaisaris->Augustus), forever alive



The companion cartouche reads AVTOKRATOR, so it must be a Roman Emperor.

Tryphon's real name was ...

The Boston Museum of Fine Arts claims that this marvel is Roman:
No way. This is '400 Florentine, probably from Bertoldo di Giovanni's workshop (Donatello's influence is unmistakable here). A very talented and now very famous apprentice may have had a hand at the torch-carrying putto.

Fakes?

After the Franz Hals, the "St. Jerome" attributed to Parmigianino has been deemed a fake by Orion Analytical, a materials analysis firm which was  acquired by Sotheby’s in 2016 (1, 2) .
I am still skeptical. I would bet that the painting is authentic. Paraphrasing G.F. Hardy,  material analysts mess ups are more common than forgers of such talent. I use the word talent on purpose. It takes more than skill to create such a convincingly early-Italian Mannerist work. Still, it being a fake is a possibility, not least because of Giuliano Ruffini is keeping his cards very close to his chest. My guess however is that there may be something problematic in the provenance of the painting, rather than in its production. I have a vague memory of seeing a possibly similar work in the studio of P. Giovanni Felice Rossi, a long time ago.

Drew Peterson

This is a long shot.

Drew Peterson was convicted of murder on the basis of hearsay evidence, which was declared admissible on the basis of an expressly passed law.

Bar hearsay there is no evidence relating Peterson to the death of his third wife and
 there is no proof whatsoever that Peterson's fourth wife was killed.

I predict that Peterson's fourth wife will be found alive.

Measurement artifact

It is curious that the Higgs hid to the last, only to be finally spotted  at the uneasy junction of two radically different measurement procedures.

PS See here for an unrelated but interesting example of scientific statistical mess up.

Spread


Assuming that the current value of the cost of default equals the excess
price of assumedly risk-free 10y German bonds over the 10y bonds of other
euronations today we get

Portugal
Spread b.p. 1057
Default recovery rate % 35
Maturity years 10

Default prob. % 100.39
i.e. assuming a default recovery rate of 35%  the market are certain that
Portugal will default.

For Italy a 50% default recovery rate yields

Italy
Spread b.p. 370
Default recovery rate % 50
Maturity years 10

Default prob. % 61.85
which isn't exacly reassuring either.

Also the following is interesting:
Greece
 Spread b.p. 3100
Default recovery rate % 5
Maturity years 10

Default prob. % 100.52
The markets, who already know that Greece has defaulted, think that  the recovery rate will be just  5%.
