 The fleet was only able to sail off after Agamemnon had sacrificed his eldest daughter Iphigenia.Strabo says that the harbour of Aulis could only hold fifty ships, and that therefore the Greek fleet must have assembled in the large port in the neighbourhood, called Βαθὺς λιμὴν.Aulis appears to have stood upon a rocky height, since it is called by Homer Αὐλὶς πετρήεσσα, and by Strabo πετρῶδες χωρίον.
