Clasping buttress: one which encases the angle. Diagonal buttress: set diagonally to the angle. A flying buttress transmits the thrust to a heavy abutment by means of an arch or half-arch.

Byzantine
London
A style which originated at Byzantium (Constantinople), the Eastern capital of the Roman Empire, in the 5th century, spreading around the Mediterranean and, with Eastern (Orthodox) Christianity, from Sicily to Russia in later centuries. It developed the round arches, vaults and domes of Roman architecture but eschewed formalized classical detail in favour of lavish decoration and ornament of emblematic and symbolic significance. Introduced to late 19th- and early 20th-century Britain as an alternative to Gothic, usually for church architecture; often called Neo-Byzantine.
