The Hecale (Ancient Greek: Ἑκάλη, Hekalē) is a fragmentary Greek epyllion written by Callimachus during the third century BC. The eponymous heroine of the poem was an impoverished Attic widow with whom Theseus stayed on his way to subdue the Marathonian Bull. On his return from accomplishing this feat, Theseus found that his hostess had died, and, in return for her humble hospitality, the hero founded a deme named for her and established there a sanctuary of Zeus Hecaleus in her honor. Although poorly preserved by papyrus fragments and quotations in ancient authors, the broad outline of the Hecale is relatively certain, and the text stands as an important witness to the poorly understood genre of the Hellenistic epyllion. It was also extremely influential and was alluded to by later Hellenistic poets and, later, Roman writers such as Lucretius, Horace, Ovid and Apuleius.
The Rainer Fragments of the Hecale are one of most important sources of our knowledge of the Hecale which are preserved on a piece of a wooden tablet now in the papyri collection of the Archduke Rainer in the Royal Library at Vienna, which were first published by Prof. Theodor Gomperz in vol. vi. of the Mitteilungen aus d. Sammlung d. Papyr. Erzherzog Rainer, Vienna, May 1893. The character of the writing, according to Wessely, assigns the tablet to the 4th century a.d.
