input: One hallmark of Aeschylean dramaturgy appears to have been his tendency to write connected trilogies, in which each play serves as a chapter in a continuous dramatic narrative. The Oresteia is the only extant example of this type of connected trilogy, but there is evidence that Aeschylus often wrote such trilogies. The comic satyr plays that follow his trilogies also drew upon stories derived from myths.  For example, the Oresteia's satyr play Proteus treated the story of Menelaus' detour in Egypt on his way home from the Trojan War. Based on the evidence provided by a catalogue of Aeschylean play titles, scholia, and play fragments recorded by later authors, it is assumed that three other of his extant plays were components of connected trilogies: Seven against Thebes being the final play in an Oedipus trilogy, and The Suppliants and Prometheus Bound each being the first play in a Danaid trilogy and Prometheus trilogy, respectively (see below). Scholars have moreover suggested several completely lost trilogies derived from known play titles. A number of these trilogies treated myths surrounding the Trojan War. One, collectively called the Achilleis, comprised the titles Myrmidons, Nereids and Phrygians (alternately, The Ransoming of Hector).  Another trilogy apparently recounts the entry of the Trojan ally Memnon into the war, and his death at the hands of Achilles (Memnon and The Weighing of Souls being two components of the trilogy); The Award of the Arms, The Phrygian Women, and The Salaminian Women suggest a trilogy about the madness and subsequent suicide of the Greek hero Ajax; Aeschylus also seems to have written about Odysseus' return to Ithaca after the war (including his killing of his wife Penelope's suitors and its consequences) in a trilogy consisting of The Soul-raisers, Penelope and The Bone-gatherers. Other suggested trilogies touched on the myth of Jason and the Argonauts (Argo, Lemnian Women, Hypsipyle); the life of Perseus (The Net-draggers, Polydektes, Phorkides); the birth and exploits of Dionysus (Semele, Bacchae, Pentheus); and the aftermath of the war portrayed in Seven against Thebes (Eleusinians, Argives (or Argive Women), Sons of the Seven).

input: From the 5th to the mid-9th centuries, the art of the Picts is primarily known through stone sculpture, and a smaller number of pieces of metalwork, often of very high quality; there are no known illuminated manuscripts. The Picts shared modern Scotland with a zone of Irish cultural influence on the west coast, including Iona, and the Anglo-Saxon kingdom of Northumbria to the south. After Christianization, Insular styles heavily influenced Pictish art, with interlace prominent in both metalwork and stones.  Pictish stones are assigned by scholars to 3 classes. Class I Pictish stones are unshaped standing stones incised with a series of about 35 symbols which include abstract designs (given descriptive names such as crescent and V-rod, double disc and Z-rod, 'flower' and so on by researchers); carvings of recognisable animals (bull, eagle, salmon, adder and others), as well as the Pictish Beast, and objects from daily life (a comb, a mirror). The symbols almost always occur in pairs, with in about one-third of cases the addition of the mirror, or mirror and comb, symbol, below the others. This is often taken to symbolise a woman. Apart from one or two outliers, these stones are found exclusively in north-east Scotland from the Firth of Forth to Shetland. Good examples include the Dunnichen and Aberlemno stones (Angus), and the Brandsbutt and Tillytarmont stones (Aberdeenshire).  Class II stones are shaped cross-slabs carved in relief, or in a combination of incision and relief, with a prominent cross on one, or in rare cases two, faces. The crosses are elaborately decorated with interlace, key-pattern or scrollwork, in the Insular style. On the secondary face of the stone, Pictish symbols appear, often themselves elaborately decorated, accompanied by figures of people (notably horsemen), animals both realistic and fantastic, and other scenes. Hunting scenes are common, Biblical motifs less so. The symbols often appear to 'label' one of the human figures. Scenes of battle or combat between men and fantastic beasts may be scenes from Pictish mythology. Good examples include slabs from Dunfallandy and Meigle (Perthshire), Aberlemno (Angus), Nigg, Shandwick and Hilton of Cadboll (Easter Ross).  Class III stones are in the Pictish style, but lack the characteristic symbols. Most are cross-slabs, though there are also recumbent stones with sockets for an inserted cross or small cross-slab (e.g. at Meigle, Perthshire). These stones may date largely to after the Scottish takeover of the Pictish kingdom in the mid 9th century. Examples include the sarcophagus and the large collection of cross-slabs at St Andrews (Fife).  The following museums have important collections of Pictish stones: Meigle (Perthshire), St Vigeans (Angus) and St Andrew's Cathedral (Fife) (all Historic Scotland), the Museum of Scotland, Edinburgh (which also exhibits almost all the major pieces of surviving Pictish metalwork), the Meffan Institute, Forfar (Angus), Inverness Museum, Groam House Museum, Rosemarkie and Tarbat Discovery Centre, Portmahomack (both Easter Ross) and Tankerness House Museum, Kirkwall, Orkney.
