Chromatic Variation in Late Antique Rainbows

Modern Reception of Late Antique Egyptian Textiles

riographic project in a volume celebrating the work of Thomas F. Mathews, who, as my teacher and mentor, set me on the path of an intellectual adventure that never fails to surprise.1 At the center of this study is a set of Late Antique Egyptian textiles assembled in an album for Dikran Ga rabed Kelekian (1868–1951), an influential collector and art dealer who was a source of historic and archa...

Bone traumas in late antique populations from Croatia.

We present the results of the analyses of traumatic bone injuries in two Late Antique (3r to 5th century AD) skeletal samples from Croatia: Zadar--located on the eastern Adriatic coast, and a composite skeletal series from continental Croatia consisting of skeletons from Osijek, Vinkovci, Strbinci, and Zmajevac. The osteological series from continental Croatia are related to settlements located...

Ancient Letters. Classical and Late Antique Epistolography [book review]

Fountain rainbows.

We present the first measurements of radiance spectra of rainbows. The bows on two sunny days (3 and 6 June 2008) were produced by the fountain in the Parque de las Ciencias, Granada, Spain, that consists of a rectangular perimeter of 40 spray nozzles. Optical thickness of the spray from each nozzle was approximately 0.5. Spectral purity of the primary bow was highest for orange and blue, reach...

Rainbows in the Hypercube

Let Qn be a hypercube of dimension n, that is, a graph whose vertices are binary n-tuples and two vertices are adjacent iff the corresponding n-tuples differ in exactly one position. An edge coloring of a graph H is called rainbow if no two edges of H have the same color. Let f(G, H) be the largest number of colors such that there exists an edge coloring of G with f(G, H) colors such that no su...
