More Pointed Arches

Visiting England’s New Forest region recently reminded me of the old bridge at Fordingbridge:

The gothic arches of this bridge bear a striking resemblance to the Admiral’s Bridge at Palermo, featured in the previous post, which made me wonder if there was any possibility of a connection between the builders of the two structures. According to Wikipedia the original bridge was built before 1252, when a grant was rewarded for its repair. Other sources give the age as about 1200, but it seems at least possible that the original structure was constructed substantially earlier than this.

The arches visible at the face of the structure are a 19th Century addition, but these were constructed with a slightly larger span, leaving the original structure clearly visible:

Unlike the bridge in Palermo, the Fordingbridge structure is still in unrestricted use, and carrying modern heavy vehicles.

Searching for bridges of a similar age and style in the region I found the Ayleswade Bridge, which is recorded as being built in c 1244, also known as the Harnham Bridge:

It perhaps seems fanciful to suggest that there might be any connection between structures built in England and in Sicily, but at the time of the construction of the Palermo bridge both England and Sicily were under Norman rule:

An old bridge in Palermo and pointed arches

The Ponte dell’ Ammiraglio (Admiral’s Bridge) in Palermo, Sicily, built from 1125-1135 (or 1113, according to the Italian Wikipedia), is one of the oldest surviving post-Roman era arch bridges in Europe.  The bridge has been restored and surrounded by a new park, but also being surrounded by busy Sicilian roads, cut off from its original purpose, and outside the main tourist area, it is little visited.

There is also little information about this bridge on the Internet (at least in English), but I did find a lengthy discussion on the history of pointed arches, and where they came from, which is well worth a read at:

Nexus Network Journal (architecture and mathematics on-line)

Thanks to the comment from Pier below, a You tube video of an event on the bridge:

ExcelPython2, Alglib and Spline-Matrix Rel 2.03

Following a comment here: ExcelPython2, Alglib and Spline-Matrix update I have updated the VBA and Python code, and added a missing Python module to the download zip file.  See the earlier post for details of installation and use, or download the revised files from:

xl_Spline-Matrix2.zip

The revised spreadsheet should work with 32 bit Excel, provided the instructions for installing Python (including Numpy) and Alglib are followed.

Bruton Town – A very old story

Bruton Town is an English Folk song featured on The Pentangle’s first album (the first LP I ever bought).  It tells the story of a young woman whose lover is murdered by her two brothers, because they do not think him worthy of her.

According to this link the song:

 is a version of the story Isabella and the Pot of Basil, made famous by Boccaccio in The Decameron, but the ballad obviously draws on popular tradition since then. It is also known as The Bramble Briar, The Jealous Brothers, The Merchant’s Daughter, and The Murdered Servantman, and can be found in 100 English Songs, edited by Cecil Sharp who collected it in 1904.

… and the Boccaccio story, together with its link to a poem by John Keats may be found at:

Giovanni Boccaccio. The Decameron (ca. 1353)
